Looks like the most recent update on my Chromebook to Chrome stable version 83 has finally enabled pass through of the serial ports to crostini. I have only tried it on my nodemcu esp32. Once you connect it, you get a popup asking if you want to pass to Linux. It then shows up as /dev/ttyUSB0 inside...

On my esp32 running MicroPython v1.12-421-g4371c971e, randint works.

I think that list is in order of need and should be followed as much as possible. Once you guys have a more defined pla...

I'm curious about this behavior. I have hooked up a precision voltage reference AD584 chip set to output 2.5 V. This is connected to one of the adc inputs of the ESP32 (set to 12 bit width and atten_11db). Taking adc data every 1 second which is published via MQTT (using the mqtt_as) to a broker. A ...

They provide Windows GUI and other software and also Linux drivers. But most can be used directly via Python ...

I too have been looking for a solution using a Chromebook using crostini/Linux. Unfortunately it is not possible as of right now as USB support for such serial devices is not present in chrome. Maybe it will change in the future.

For Arduino, there appears to be some sort of web app and ide.

Not sure about bs4 but a quick Google search shows that there are available APIs for weather data, for example, openweathermap Haven't used them but using requests module they should return json that should be figurable with the micropython json module.

Thanks very much. I will check this out.

Can you add the --chip=esp32 to the erase_flash option? These are the commands I . usually use: esptool.py --chip esp32 --port /dev/ttyUSB0 erase_flash esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z 0x1000 esp32-20190125-v1.10.bin It is possible that the download of the fir...
