Sample Code to control LED/Motor using Web Serial

[beniroquai]

It would be nice have a simple installation-free online tool that connects to the ESP board and sends some commands to test LED/Motors, etc.

The sample code can be found here.

It gets rendered here: https://youseetoo.github.io/indexWebSerialTest.html

It uses the following JS library: https://github.com/makeabilitylab/p5js/

So far: It's connecting, but I guess something with line-break or Baudrate is not setup properly.

@renerichter, would you mind helping here? :)

Hey @frauzufall, as discussed earlier today: I'll just link you here.
This repository is the current firmware for the UC2 microscopes. We have the "flashing" website => youseetoo.github.io
which makes use of the webserial protocol. I have started creating a super simple example page as mentioned earlier:

I think people in general are overwhelmed to install 100 python dependencies. So using the browser instead would be wonderful. (almost installation free) + we can use the webcam interface to readout the videos :-)

A long-term dream would be a platform that entirely runs in the browser, but perhaps we could start with small steps and just turn on/off an LED.

The general structure of the commands is somewhat documented here:
https://github.com/youseetoo/uc2-esp32/blob/mergeBD/main/json_api_BD.txt#L102 (e.g. for sending an "act" command to the ledarray). The whole concept is inspired by the REST API.
If you have a spare ESP32 microcontroller, you could try flashing the firmware and try the javascript code to see what happens. :-)

The python library is currently hosted here: https://github.com/openUC2/UC2-REST/tree/master/uc2rest

Would be great if you can have a quick look. My guessing: A Baudrate/line ending problem in the serial connection or something like that.

@renerichter perhaps you are keen on optimizing/beautifying the sample page? ;-)
