TLDR
- CapTech Workshop. Was great!
- Acted upon a split between a FPGA long-term approach, and a non-FPGA one. I remembered those good old times when this was a possibility.
- Damn it. What if I could dig into this? Not µC, rather an extension for an existing computer.. or mini computer.
- Saw some ideas on the Arduino's side. Separate ADC.
Resources
- Is Pi powerful enough for an oscilloscope project?
- Raspberry Pi as an Oscilloscope @ 10 MSPS

BBB
- How to use it?
  - http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/05/22/bbb--working-with-the-pru-icssprussv2
  - For low-speed comms, conventional I2C or similar protocols can be used, and there is no need to use a PRU. For high-speed comms the PRU may be extremely useful because it can service the hardware with no interruptions due to Linux context switching, and no overhead is experienced by the main ARM processor. Here are some examples that should be feasible; basically quite a few possibilities, such as
  - - interfacing to a fast ADC (e.g. analog capture) ,
- https://theembeddedkitchen.net/beaglelogic-building-a-logic-analyzer-with-the-prus-part-1/449 BBB is a 100MHz logic analyzer on a BeagleBoneBlack
- Demo over the http://beaglelogic.github.io/webapp/
- http://r.git.net/beagleboard/2013-10/msg00204.html
  - Can the PRU be used to interface the Beaglebone to external ADC? I need to capture 500 micro-seconds of data at a 5 MHz rate.
  - -> It depends on the interface to the ADC. There is a parallel capture interface that will easily run that fast, and you may be able to use the bit-shift interface to do serial or something like SPI if the PRU's capability lines up with what your ADC wants to see.
- http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/08/04/bbb--high-speed-data-acquisition-and-web-based-ui
  - In its current state, it grabs analog data from an ADC, and dumps it into memory on the BBB, ready to be displayed or further processed. It could be used for gathering analog information from sensors, CCDs or other data acquisition use-cases. To be reasonably useful, the desire was for it to support 20Mbytes/sec of data or more. It does achieve this, but it is for further study to find higher speed methods.*
  - This is not such a bad idea, because in future the ADC could be swapped out to a (say) 10-bit ADC with no code change on the PRU.*
  - Once the data has been captured (2000 samples in this example), the command byte is acknowledged, so that the Linux hosted application can know that the PRU has completed. The PRU now sits and waits for a new instruction from the Linux hosted application. -> works for us - fixed depth = fixed # of samples
- Buffer to be used : detailed at http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/08/04/bbb--high-speed-data-acquisition-and-web-based-ui
  - ''These were extremely important for two reasons. One reason is that the pins to the BBB that I wished to use need to be isolated during power-up, because they are used for selecting the boot method. If there was any unusual level on the pins upon power-up then the BBB will not boot from the eMMC. So, a tri-state buffer is needed. The other reason is that there is a fair bit of capacitance and it is highly likely that the ADC may not be able to directly drive the pins at high speed. I actually came across this problem while trying to connect a camera to the BBB. I struggled for days without realising that the camera could not support the load. So, the buffers are likely to be essential for most designs using the pins that were selected. I used a 74LVC244A device as a buffer. Note that the clock also needs a buffer, unless significant jitter is acceptable. No tri-state is required here, so I used a MC74VHC1GT50.

Orange Pi Plus 2 : A nasty little thing
BBB as always coming mostly from element14 Some limits - not exploiting all ? http://exploringbeaglebone.com/chapter13/#The_ADS7883_Single-Channel_12-bit_ADC_1MSps_max SPI speed with BBB : http://fr.mathworks.com/help/supportpkg/beagleboneio/ug/use-the-beaglebone-black-spi-interface-to-connect-to-a-device.html (up to 32MHz) - which is
16 bits : is it possible to set all 16 pins on pru0 as inputs? I saw you mentioned something about disabling the microSD functionality on the BB to get access to all 16 pins, but I wasn't exactly sure how. -- heartofasquid I thought the PRUs had a 16bit parallel capture mode or are all the pins not available on the BBB? (need to consult the docs) section 4.5.2.2.3.2 of the tech ref spruh73c.pdf One thought I had was to use both PRUs to capture alternate bytes/words but that was just a thought, again are all the pins available? I'd made a mistake, it looks like all of PRU0's GPI pins may be available, if we are happy to lose the microSD (no big loss - there are other ways to get data in/out of the BBB). So, we can theoretically get high-res captures up to about 15bits, if we need 1 pin for the clock.

https://www.adafruit.com/products/2478 : 240by 320 screen, touch, sd
- The display can be used in two modes: 8 bit or SPI. For the fisrt you'll need 12 lines total. Second mode requires only 5 pins total but is slower than first.
- In addition, 4 pins are required for the touch screen (2 digital, 2 analog)
- Tuto : https://learn.adafruit.com/adafruit-2-4-color-tft-touchscreen-breakout

Need for a filter to get be sure , there's a low frequency component that remains: to remove- and to center around 0V ?

Let's cut it to 500kHz ?

For headers, we have
- 12 input pins on P8 for PRU1 and 1 input pin for PRU1 on P9, these have been assigned for 12bitADC+Clock and the rest,
- SPI for DAC,
- Buffer enable and motor control have been assigned to PRU0.
For the controls in prototyping:
- SW1 controls the gain range for TGC
- SW2 controls the input range of the ADC,

Nice reading =)

Basecamp outlines their goals -- which they say have always been the same -- on their website:
- Have fun
- Do exceptional work
- Build the best product in the business
- Experiment
- Pay attention to the details
- Treat people right
- Tell the truth
- Have a positive impact on the world around us
- Give back
- Keep learning.
"We’re also big believers in business 101. We don’t spend more than we earn, we don’t waste money on things that don’t matter, we don’t give away everything for free and hope we’ll figure it out before we run out of cash. We’re in business to stay in business, and we have 15 profitable years in a row to back it up."

Some reads on PRUs:

2016-04-11 Microcontrollers choices

Choice of a uC: "le boulot des microcontrollers, ce qui me gene sur l'espruino c'est le manque de sortie wifi - si on veut sortir des donnees en wireless." Deux choix se profilent

WICED : STM32F205RG 120MHz ARM Cortex M3 MCU : 17 timers et 3 × 12-bit, 0.5 μs ADCs with up to 24 channels and up to 6 MSPS in triple interleaved mode, 8- to 14-bit parallel camera interface (48 Mbyte/s max.)
Le WifiMCU : EMW3165 : M4: STM32F411CE @100MHz, DSP+FPU, 1×12-bit, 2.4 MSPS A/D converter -- Ce qui me fait peur est un WifiMCU de base en LUA, a voir comment repasser sur du plus bas niveau. L'avantage par contre c'est qu'il est dispo chez hackspark, et coute 18€ au lieu des 35$ du WICED =)

Remarques : Avec le M3 tu perds les instructions DSP et un FPU optionnel (cf https://en.wikipedia.org/wiki/ARM_Cortex-M). Par contre je ne sais pas si c'est correctement exploite, ni si on en a vraiment besoin.

Il y a aussi le Module Particle "Photon" http://www.lextronic.fr/P37394-module-particle-photon.html (M3 120 MHz et wifi) ou l'Arietta http://www.lextronic.fr/P32050-module-microcontrole-arietta-g25.html

Playing a bit with ADL5511 : there's an EREF
We use offset remover (suiveur + gain de 2.5), and second op will do amplification, cause envelope output swing is saturated at 1.2-1.3V, We can use 2..2,5 gain to deliver nice and neat 2,6 ..3V input swing for ADC.

2016-04-20 Modules

Previous Generation

Murgen : the annalist.. already done, a former project !

Current batch

Goblin: the analog heart, was drafted as well during Murgen.
Tobo: the HV/pulser, based on a drafted close to Murgen.
One-Eye: MicroControler - Arduinos
Mogaba: Alimentation

Second generation of fun! Learning microcontrolers and advanced simulations

2016-04-25 Working IRL and motivation

http://bengarvey.com/2016/04/24/real-work/ How many times today did a customer notice something you did?
http://www.stubbornella.org/content/2013/02/26/why-i-run-my-business-like-an-open-source-project/
http://www.atlasobscura.com/articles/the-rise-of-illegal-pirate-libraries?utm_source=facebook.com&utm_medium=atlas-page

I define Real Work as

Work that creates an immediate and positive change in your product/service
Work that is a direct constraint to the completion of A
Work you have been uniquely hired to do.

2016-04-26 Motivation

"I am not a visionary, I'm an engineer," Torvalds says. "I'm perfectly happy with all the people who are walking around and just staring at the clouds ... but I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in."

Received tobo !! yeayyy
Playing with Doj and assembling the board (tobo, goblin, oneeye and mogaba). Should be enough to get first images.
power seems OK, first pulses look nice
Todo: test with my transducer for Cletus, and with ATL3
Thanks to Virginie for her support on debugging Doj !!

2016-08-09 Moving forward

Roughly, all the modules are fine. Emulator is done and tested. Some tests today:

Test Analog Processing + ATL3
- -> https://github.com/kelu124/echomods/blob/master/goblin/2016-08-09.md
Test Emulateur de signal + Analog processing
- -> https://github.com/kelu124/echomods/blob/master/silent/Readme.md

What the next steps are :

High priority:

Use PRUDAQ
- Clip the signal between 0 and 2V
Get image from the retroATL3

Medium Priority:

Bitbang Goblin's SPI directly
Resume documentation

Low Priority:

EMW3165 to move forward
Cletus for Servo + Piezo (and mech parts) - using SmartMaterials piezos

2016-08-10 Simple things

Clipped the signal
Documentation ongoing

2016-08-30 Some good news

Got some feedback of PRUDAQ's people on the doc, thanks to them for this contribution!
Zach's been back. Let's see what can be done.
Prof Charles is going to be in Paris: let's meet!
Been invited to speak at Hackaday's show for its prize on Nov 5th
Trying to get the latest HV7360 from MC.. seems difficult to say the least

2016-08-31 Habitat numerique

Thinking about the use of the "Logiciel and Objets libres, animer une communaute autour d'un projet ouvert"
Interesting : STBone - BeagleBone form-factor STM32F427 board
Doing some thinking about the servo part -- should be integrating a feather + screen to help debug the output =)

2016-12-26 Raw ideas

Max RPi speed : http://d-fence.sytes.net/raspberry-pis-gpio-speed/ @done --> do it with the Rpi0
- http://codeandlife.com/2015/03/25/raspberry-pi-2-vs-1-gpio-benchmark/
- Using the same experimental setup, the Raspberry Pi 2 is about 2 to three times faster. The fastest is still the C native library, topping out at just under 42 MHz.
Thinking of 20E-214 and moving to Alibaba for wireless probes. Will F.'s support reach?
Using Vitamins for the gyro's probe. What name still for it? Longinus?

2016-12-29 Moving forward

Getting to think of the 20E-214 ones =)
Chat with 1Tech, and the guy Patrice. Motivating.
Trying to get some stuff from the arduino, namely to get it work as a server. Far from being finished, on it.

2017-01-02 Merry new year

20E214
- Getting a propal from PR
- Fouad offering to test the 7.5MHz linear

“We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.”

Presentation to ESPGG, participated to.
Hardware:
- went to solder some stuff at HD
- UltrasHound -- moving forward
- Beaglebone PRUDAQ image added.
Added some details (better raw image quality) to the SigProc 101 jupyter notebook.
Interesting paper on Theory of Change.
Peter confirms the probe is on its way.

Thinking about an update for a neat, silkcreened, well designed motherboard. Would be excellent for Altay, Felix and maybe
Been doing some progress about the HV - working with Lorena to get one on board. I'll have 2 pulsers, will ask for 3. In total I'll still be able to send to (Afreen/Felix/Altay) + one for the GroupGet friends. Would leave me with one.
Afreen still working on the feather, after contacting the PRUDAQ guys.
Get Felix on Slack?
Call scheduled with Fouad on tuesday
Making progress on 20e214 - control of the probe OK. Display remaining, then CSV saving.
Taking more time about the Slack bot: lower priority
Update by Tobey: he found a way to compare PDFs.

2017-03-01 RPi0

See this log

2017-03-02 RPi0 bis

Given RPi0 capabilities in terms of GPIOs - why not push it to 20Msps, 8 bits, for the cape?

2017-03-05 Grmbl netty

Netty isn't nice... but just got my article accepted by JOH !

2017-03-19 Finish Doj

Working on Doj and releasing the KiCad definitive code - available on OSHPark.
PCB of the RPi0 high-speed ADC is ongoing !
Getting the last touches to the JOH article.

2017-03-20 Doj ... unfinished

Indeed. Forgot to add a ADC input directly from a strip, two strips for PulseOn and PulseOff, and a way to control the servo from the Pi.
Also starting the new season of the HackadayPrize =)
Still some issues with bomanz (on HAD) PCB. Some pads suck. I guess I'll order the board from OSHPark along with Doj's and solder all these tiny stuff. Not so many actually.

2017-03-21 Moving forward

Posted the Chinese probe project on Hackaday. Will play with the probe using a RPi framework. Should do the trick =)
Following up on 6Msps upgrade, mother board seem OK, silkscreen to do, then Pi1 and Pi2 to follow.

Still about the RPi0 high-speed ADC : if I can't get above 10Msps due to a memory copy time, I may be able to double the speed by having 2 ADCs interleaved... it's to test!
Some answers for the CMUT stuff.. let's see if it's going somewhere !
ATL probes connectors are LEMO 18 or 19 pin.

2017-05-22 Testing Doj v2

Got the PCBs and tested them. Yeayyy, they work! Slight hiccup with the ADC, nothing dramatic though =) Actually, two pins have a double use along with the ADC pins. Dumb me :p

2017-05-29 Testing Doj v2

Pushing some pics of the devkit 2.0 - note that this config allows pulse transmit. Pulse from the pulser, receiving through the analog front end.. and acquisition managed by the adc and raspberry.
Note to self: this config requires a "good" usb power supply. It succeded with a 5V 750mA power supply - but failed from USB.

2017-07-28 Thinking of an end

Got some amazing responses to the post on HN, held the 1st pos for an hour +, got over 200 ups, that's quite enough =) I guess I'm coming close to an end on this project, and my target would be to try and have a presentable project before Year 2. The five key milestones:

Outreach: I have sold 10 kits so far, have ordered 5 sets more to a CN PCBA. Will sell those - and let people choose what they want when they'll want to play with those. I guess I'll have the community Milestone reached when someone provide a significant improvement / publishes thanks to this kit. Status: 50%. Bonus point if a unreached continent so far is involved.
- ENDOFYEAR: 15 kits sold, CN not good, MF ongoing (20171217)
Money: thanks to the small margin on kits, and hackaday prizes, i'm quite cash neutral as of today. Having the 5 kits sold would permit financing the acquisition of the unmantled CN probe. Status: 100% Bonus: trade the chinese probe on leboncoin / ebay. Status: 0%
- ENDOFYEAR: still waiting (20171217)
Product: I wanted to have a ultrasound hat done. I now have this ADC pHAT done, which can be perfected, but it's quite a win, so a simple 80V monopolar ultrasound board (independant from the motor / multiplexer) could be reached by Nov. Status: 0% Update: could be good to use the probe head to do a full portable probe =)
- ENDOFYEAR: Ongoing with Matty (20171217)
Documentation: There are a couple of notes here, I'd love to see all of those gathered / processed / put into a braindump. Gitbook is good enough, but lack structure for raw knowledge dump. TODOS include:
- Listing all docs under YYYYMMDD
- ENDOFYEAR: Quite happy, having added experiments (20171217)
Future I'd be keen on having a 8 to 16 elements module prepared, just so to prepare the next gen and passing over of the project. Jan and Ivan to support. Status: 0% Muxing using ATTINY85 ?
- ENDOFYEAR: Shifting to chaotic masks ;) (20171217)

Nice to have:

A slack bot? It would be fun to have a supporting bot to answer queries, like "where are the elements benchmarked, how do you process dicom, ..."

2017-08-05 Moving forward towards the board

Added something about the S3 probe
@done Adding the descs for modules and power needs
@done Removing double Autogen tags
@done Main readme as TPL
@cancelled DICOM rest of images
@todo test some compressed sensing using golay codes on a single element piezo

Commands
- modprobe foo parameter=value
- modinfo ambassador for params

Sometimes a kernel modules allows setting a parameter at run time. In this case you'll find the parameter under /sys/module/modulename/parameters/, with writable file permissions. The debug parameter of the ambassador module is an example of such a parameter. Set a value to this parameter with a simple echo command:

echo -n 1 > /sys/module/ambassador/parameters/debug

FPGA

Open-source: ICE40 & RPi
Perfs: SRAM + HX4K at least: IceZero ? Take the design, throw in 8Mb instead of 4Mb
- IceZero board design can be reused
Silkscreening:
- Keeping a clear markup of the different functions
ADC: 10 bit, 65Msps
- 10 bits measures (or pseudo-12 with decimation ? by x3)
- 6 bits remaining by acq: 2 top tour, Pon, Poff, 2 IOs
Interact
- 2 buttons
  - Manual Trig
  - Select mode
- 4 LEDs
  - Single mode
  - Loop mode
  - Acq (ready: on, data in: flashing)
Modes:
- Single capture
  - 200us long captures at 65Msps : 208kbits
  - Capacity of close to 35+ captures if needed in RAM
- Loop
  - 130us acq at 24 Msps over 16 bits: 57.6 kbits
  - That's more than 130 lines over a 8000000 bit SRAM
Transfer back to RPi through SPI
Variables (to be stored as a header of the file sent back)
- Pon length

- N acq -- number of acquisition
- Implicit:
  - ADC bits used

@done Brainstorm for @senjak information design:
- Main branch (on GH) - sync'ed from matty folder
  - Presentation (on dmn.org as a static page)
  - Sources
    - Upverter
    - FPGA
    - RPi
  - Experiment examples

2018-01-28 Updating Senjak

Fun with TTGO - interesting full setup with https://fr.aliexpress.com/item/TTGO-TS-v1-0-v1-2-esp32-1-44-1-8-TFT-MicroSD-fente-pour-carte/32847643640.html
Removed MattySenjak clock, expecting new
Bought some ESP32 to play with
Preparing OSHW ?

2018-02-01 Un0rick clock oki

Clock is soldered again!

2018-02-02 Flashing Un0rick oki

Done! With the code, it works. I just need to rmmod ftdi_sio and usbserial =)

2018-02-03 Un0rick and RPi

Still some issues having SPI work.. let's try through RPi. Been adding the the jupyter to the board.
Why not have the CS0 on IO4, taht's

2018-02-13 Un0rick moving good

work making progress -- DAC working for the gain, Pon and Poff work, setting up the registers work..
Need to get something else than 0xAA on reading though =)
un0rick.cc booked -- will be home page / gh-page.
@done un0rick site to have plenty of stuff
- shop for stuff (or paypal ?)
- doc for documentation (from a gitbook)
  - Generated from echomods
  - includes list of datasets
  - includes article
- data for datasets
- git links to github
  - gh-page is homepage
    - Just a landing page

  - all of this in a self contained PDF containing
    - pitch
    - scientific article
    - poc-style
    - some goodies
BTW, un0rick light could be good! (UP5K, HV7361+MD0100!, no RAM, just pulser, few buttons, ... :) ) -- to be discussed / price checked.

2018-02-18 un0rick deadend

https://kelu124.gitbooks.io/echomods/content/Chapter3/matty.html Nothing works yet on the MOSI line... strange to read those. Version from 11/02 works still. To be explored!

On the good side, I had time to test the new Elmo v2 and Alt.tbo v2 boards:
- Comparing new and old pulsers
- With a new driver for the pulser and ADC

2018-02-25 un0rick moving again good

Getting first images ! Yeayyy =)
So now, getting to:
- @done Create matty module
- @done Publish first drafts on un0rick GH / GH-pages / gitbook
- @done create un0rick page on echomods gitbook

2018-03-16 Bard probe 1

Worked on a bard probe with matty
An interesting patent is here -- found working on the patent parsin' graph tool
- The more I glance at it, the more fascinated I become...
- There is no motor! Just electromagnets =)
  - Then no need for a stepper motor
  - it may be the case that
- The signal coming back is an already processed signal!
  - It means the pulse should come from another part of the board... ie another pair of cables.
    - Black and white? -> 5 ohm between this pair.. why not?
  - What about the other logics?
Next steps: trying and get the reference manual
Get full echographs boxes on ebay =)
- Plug plugs on headers while running

2018-03-20 Updates

Getting a Bard Site Rite III in the mail soon ? ;)
Probable supplier for mechanical probe in the pipe too !

2018-06-25 Or not

Article: Impressive Development of a Low-Cost Medical Ultrasound Scanner Using a Monostatic Synthetic Aperture
- I'm a noob at this, but it seems that MFFS uses fixed focus piezos, but MSAS does focusing in the software (hence synthetic aperture) using a piezo of known size. That's an interesting alternative to focused piezos.
- Some other interesting insights, like using "Quality Assurance for UltraSound (QA4US) software" for image quality assessment, or also the architecture they used (an ARM, 14-bit ADC at 12Msps), or even the fact that the piezo is in direct contact with the skin, or a motor using a Voice Coil Motor.
- @todo add the MSAS principles to the un0rick article
Module
- define PI2 or get_rpi_version

2019-08-30 FFT and ice40

Summer time and deconnection !
some progress on lit3
- getting help form @ico_TC : https://twitter.com/ico_TC/status/1165699274652475392
- going back to UW, checking with Farad too.
- Need to stop bleeding resources ;)
- Need to fix thermometer
Gathering some signal processing on fpgas
- https://github.com/mattvenn/fpga-fft/blob/serial/docs/fpga_usage.md

2019-10-26 Some lit3 progress

Good progress, stupid capa was in the way on ADC clock. Now acquisitions seem more okay:
- here some good experiment
@todos updates on new pHAT
- remove this capa, remove i2c pullups for the thermometers (that was cost 5$ ! :/ )
- connecter le ice40 au i2c rpi
- pouvoir connecter des ios sur l'uart du rpi
- router les gpio daughter existantes plutôt sur les pins pcm du rpi pour un jour essayer de sortir des données en i2s (GPIO26, 20, 21, 18)
- du coup, mettre possiblement les Pulse controls sur des GPIOs non spécifiques comme GPIO05, 06, 13, 19.
- Niveau header RPi, on peut connecter les SPI_EXT MISO / CS du coup.
- Use 5 first bytes of a read to store the bin number / board ID ?
Need to make progress on this RTL-SDR for ultrasound ;)
@todo find the right jekyll theme to leave gitbook
- see https://help.github.com/en/github/working-with-github-pages/adding-a-theme-to-your-github-pages-site-using-jekyll
- https://pmarsceill.github.io/just-the-docs/ seem to fit the bill =)

2019-10-27 Again lit3 progress

Dynamic DAC seems better - however some IOs are off.
CLosely here, and then some: hardware finetuning (TMP and ADC C at minimum)

2019-11-24 10km Paris Centre

Ran again 10km
lit3rick on final form to be delivered by 2/12.
Andrew for some symbiflow support ? DFT + i2s ?
Got the sw45b probe off. Interesting designs.
@todo hack the diasonics heads.
Ported the pyUn0 for un0rick to python3 .. yeay. Thanks to Fab's pull request.
Awesome SAO: https://hackaday.io/project/164346-andxor-dc27-badge/log/165849-dc27-doom-sao-hurt-me-plenty

2019-12-06 St Niklaus

lit3 received, doesn't burn. yet. icoprog can flash the flash. but fpga won't boot from it.
Connections seem OK
- icebreaker-sch.pdf says the connections are fine
possibly need to make clean icoprog
or to swap IOs for programming, while
beware, for flash programming, SPI_SS needs to be kept floating high. Floating.
@todo keep an eye on "BRUEL KJAER ULTRASOUND" =)

2019-12-12 Article ongoing
