With pslab-python 2.6.0b0, firmware can be flashed using the command pslab flash --port <portname> <path_to_hexfile>
No need to specify baudrate :)

Please test the RTC and SD card before mass production.

I removed one MCP4822 and sent the updated PCB to manufacturer, use one MCP4822 for both voltage source and current source. I asked for quote for MCP6S21, none of the suppliers give reasonable price.

Forgot to mention during the meeting, but in fossasia/pslab-firmware#133 I also remove the Unified Host Bootloader Application, since we don't need it anymore now that mcbootflash is complete.
Alexander Bessman
@bessman
Repository split is done! Bootloader now lives at https://github.com/fossasia/pslab-bootloader, and https://github.com/fossasia/pslab-firmware contains only the application-layer firmware.
I would like rename the default branch of https://github.com/fossasia/pslab-firmware from 'bootloader' to 'main', but have insufficient permission level to do that @mariobehling
I would also like to unprotect the old 'master' branch and rename it 'legacy', as well as protect the new (renamed) 'main' branch.

Oh, and a heads up to the other firmware devs: Since the cmake-microchip submodule has moved, you may need to reinitialize it. @CloudyPadmal @RafaelLeeImg

@CloudyPadmal
Perfect! Thank you @bessman !!
I was thinking now that there's a separate repository for bootloader and it's pretty much complete, shall we make a release in the repo?
Alexander Bessman
@bessman
Good idea. Should we call it v1.0?
Padmal
@CloudyPadmal
Yes, sounds good!

I tested the SDCard and it can be read and written.

Hey guys, quick question please. I have been to every site listed on the pslab.io website looking for a place to order the Pocket Science Lab Board. Every one says it is out of stock. Any idea when it will come available again? This stuff is right up my alley and I'm so glad to have stumbled across it on Github. Great work!

Hi, I want to contribute to pslab. Help me how I get to start with it. I have knowledge of Python, Django, Django rest framework, ML, and Deep Learning. :)

Hi @anurag629 - there is an introduction to PSLab here in the docs: https://docs.pslab.io/introduction.html

TIL: https://pid.codes they give free USB VIDs/PIDs to open source projects from a pool they managed to allocate
I have a RISC-V dev board here based on the CH32V307, capable of USB, where I can just set the VID/PID as I like.
(vendor/product ID)
ended up there looking at github.com/hydrausb3

@Shawn-Armstrong

Hello,

I see that you're developing the next version of your PSLab board. Is there anyway I might be able to purchase an older one or perhaps when I can expect to see an alternative sold?

RafaelLeeImg
@RafaelLeeImg
I made a pull request. There are too many modifications, details are in the log. PCB modifications other than the final version are not included in the commits. I removed them due to the size expansion of the repository.

@mariobehling
@RafaelLeeImg Any idea how to get the automatic build passing?
Padmal
@CloudyPadmal
I checked the errors thrown by DRC and ERC, they are not critical errors. They are just trivial errors such as missing noconnects, different pin definitions (output pin connect to output pin) etc.
Mario Behling
@mariobehling
Ok, good. How much time before the PR can be finalized? Could you help to fix this PR?
@vgfsrhkbgd:matrix.org @bessman Do you want to add the points you found in the prototype in this PR or in a separate issue? CloudyPadmal/pslab-hardware#8

Hi, I see for some time that the PSLab boards are out of stock. When do they become available again?
Marco A. Gutierrez
@marcoag
@bessman are there any python examples for the pslab-python library? It would be good if we have some for tomorrow's workshop
Mario Behling
@mariobehling
Ok, just talked to Marco. For example:
  • A Python script that reads turns on an LED
and does some stuff like turn on and off
Alexander Bessman
@vgfsrhkbgd:matrix.org
[m]
Well, every function and class have documentation with a simple usage example. Beyond that, there are no organized examples.
Mario Behling
@mariobehling
Ok, Marco sees the headers, but he is not clear yet about more. He checked the servo headers and wants to try.
Is there more sample code for humidity (HL 83 rain sensor)
Alexander Bessman
@vgfsrhkbgd:matrix.org
[m]
Turning on an LED could be done using the current source pin (PC, I think is the label). But it's not powerful enough to drive a bright LED.
I think the HL83 is one of the old sensors which hasn't been updated for the new API. Really old parts of the codebase is often undocumented.
Mario Behling
@mariobehling
He would love to have a .py file
