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...

Hello, @pythoncoder: after several tests I cannot have the blit method doing a rotation. Even if the method accepts framebuffer of different formats, the problem seems to be, as you mentionned, the transposition of the coordinates. I tried many different combinations but none give the expected resul...

Hello I did it! It works :-) The method is a bit like you said @pythoncoder. I declare and use a framebuffer in landscape mode: format MONO_VLSB I write text in it, I can also use other framebuffer methods (line, rectangle, etc..) And when ready move it to another buffer to send to the e-paper. And ...

Hi Peter, thank you for taking the time to answer. You are right the set_rotate method belongs to EPD class and won't rotate a buffer filled with framebuffer methods. Unfortunately there is no framebuffer rotate method, but there is a framebuffer method to write text, and there is no EPD method to w...

Hello, after 3 days struggling with that I come here to ask for help, if possible. I have a Waveshare ESP32 driver board + 2.13inch e-paper display (B model: 3 colors) I have successfully flashed Micropython : MicroPython v1.10-54-g43a894fb4 on 2019-02-07; ESP32 module with ESP32 I use mcauser Micro...

Hello, I'm playing with the ESP8266 uart and doing some communication tests with an arduino. The hardware is ok the communication works fine (of course I use a 2k2 + 1k voltage divider for Arduino 5V to ESP 3.3V) Correct me if I'm wrong but I notice that in the documentation here: https://docs.micro...

Hi if you write from machine import Pin then you only import Pin from the machine module if after that you write pin = machine.Pin(2) then of course uPython doesn't know the module machine and gives this error try to change to pin = Pin(2) another method: import the full machine module and use it im...
