MicroPython Forum

Hi Peter, I actually already found your tutorial and also this one . I have tested some exemples. I must say that I'm impressed by: 1 - The possibility to run simultaneous tasks, the computing power of so cheap hardware (almost computer no more microcontroller!) 2 - The quality and of your doc Again...

Thanks for clarification @pythoncoder

Ok it makes sens the built-in modules aren't in the Micropython-lib but they are well documented in the doc so it's fine. And the modules in the lib are current.
And unfortunately I've hit uasyncio...

So I now feel on a stable base! Thanks again

Hello, I wonder how Micropython-lib is accurate/up-to-date/organised related to the documentation For instance: I flashed the latest stable v1.13 on a ESP8266. From REPL I can do import umqtt.simple (or umqtt.robust) and use it as expected. However if I want to read the code of that module to unders...

Hi!
Not sure if this help but a few years ago I used pymodbus on Raspberry pi it was not very difficult and worked well, it's Python not microPython but may help
Also there is this micropython-modbus for ESP32 (never tested) https://github.com/techbase123/micropython-modbus

Hi! Actually very interesting discussion. @dhylands you are right the proper way to access the module global variable "bar" is: "my_module.bar" this avoids confusion, keeping in mind that the main programme global variable "bar" is another variable. @pythoncoder Yes this is a Python strength: the gu...

Hello, We know that using global variables isn't a good practice. But it's sometimes convenient and Python permits it. However I was recently surprised to find that global variables are global to a module not across all modules. Reading the doc teachs me this is normal behavior. So that's ok when yo...

Hi!
MicroPython for ESP32 only allows ADC1 as mentioned here: On the ESP32 ADC functionality is available on Pins 32-39
Adafruit ESP32 Huzzah exposes ADC2 but also pins 32 & 33 for ADC1https://learn.adafruit.com/adafruit-huz ... er/pinouts It should be possible to use one of these.

Hi @pythoncoder thank you very much for your support. It works! :-) It took me sometime because I’m not comfortable enough with python class definition ( self and super() are still a bit obscure, but I learn!). I had to change some minor things in this DummyDisplay class and this took me time and tr...

Hello, @pythoncoder: I’d like to have bigger fonts so I’ve check your micropython-font-to-py repo as you suggested here above. But so far I had no success. I understand as per your documentation that when using the writer as in: wri = Writer(device, font) the device must inherit from framebuf But in...

Hi! @devnull: You can try this code, it's adapted from my 104x212 to your 200x200, maybe I've done some typo. I cannot test it since I don't have a 200x200 e-paper display. If yours is black only remove all lines with reference to red. It may give you a path to follow even if doesn't work out of the...
