@CyReVolt:matrix.org Sure, I will ask. Thanks

The Glasgow is very much like PSLab, but based on an FPGA.

Where would you see a difference to what a future PSLab FPGA could offer compared to the Glasgow board?

CyReVolt
@CyReVolt:matrix.org

I don't see one. The main value I see in PSLab is the apps with the full stack. The key step for someone to get started - in my view - is to learn how wiring things up leads to getting something to show up in the apps. It's that moment when someone realizes "I put this together and understood what it means". And because they have the app, they can focus entirely on the mechanical and analog world. Does that make sense? :-)
And I just got some values out of the TCD1304, I think. I have no idea what they mean though. They range around 3740-3750 or something like that.

Can someone with the required rights please make a new branch off the master branch, so that I can open the logic analyzer draft PR against it?
CyReVolt
@CyReVolt:matrix.org
[m]
Just rebase and open the PR against the current one onto upstream kartikaysharma01 (Kartikay Sharma) - it makes no difference
your branch only needs to be applicable to upstream master
CyReVolt
@CyReVolt:matrix.org
[m]
So what I mean is that git is distributed; PRs are just a GitHub thing. I.e., what matters is the patchset, which is what goes to upstream.

Regarding FPGAs, again:
Esden and others are working on an FPGA demoscene platforn; see https://twitter.com/esden/status/1419894580166598657?s=19 or join on Twitch, where they stream live :)

From the current chat at gamozo's stream:

It will be a lot of fun. The RISC-V based retro inspired console that drr developed is a great IP to run on this platform. As well as the Doom implementation and a few more things.

Kartikay Sharma
@kartikaysharma01
The android and desktop versions of the logic analyzer seem very different. Is the android app out of date? Mario once did mention that the android app is more mature. I was just wondering if I should go through the android code too. Will that be necessary?
Kartikay Sharma
@kartikaysharma01
Also, we allow just two channels as a list for the logic analyzer. I believe the reason behind that is because we can map just 2 channels.

I have seen the PSLab v{5,6} schematics doc for refactoring UART in pslab-python and I need some clarification for proceeding further.

  1. PSLab v5 uses only one UART port, which is shared for USB, WIFI, BT and External. Right?
  2. Since all of these shares the same port, only one can be used at a time.
  3. UART pass through has no use in v5.
  4. Since WIFI, BT uses the same port as USB, we can send commands and get result directly via wifi or BT. Right?
  5. PSLab v6 uses two UART port, one dedicated for USB and another for WIFI, BT, External.
  6. What is the use of UART pass-through? Is it only used to send commands and get results via wifi or BT, since both are in separate UART port?

Thankyou.

As the final GSoC evaluations start on 16th, is there a preferred platform for the final report? I personally would prefer Github Gist.

Regarding UART set_mode and set_baud:

Currently i am trying to implement it in firmware for uart2. In this i searched for possibility of setting baudrate, stop_bits, bits and parity. without re-initialize the UART but no success.

Also for set_mode do we include whole mode register(UxMODE) of uart OR setting stop_bits, bits and parity is enough?

quite nice: https://jyetech.com/
And I've looked into current Electron tooling. The basic choice was between boilerplate code and electron-forge, a full-blown utility that I went with. I'll see how it goes.
IPC is the most cumbersome part. That is the next step (and mostly depends on the current Electron version).

@bessman is this what you heard about? Cordova can target both Android and Electron.

Hey everyone, I hope you're all fine. I'm on my way to Berlin now and going to stay until Thursday, in Mitte.

There are some trivial changes needed for pslab-android app layout files. May be we can use Hacktoberfest contributions to sort it out quickly.
