Problem configuring Waveshare E-Paper ESP32 Driver Board

Postby OldSchool73 » Tue May 12, 2020 12:23 pm

Hi

I bought a Waveshare E-Paper ESP32 Driver Board (https://www.waveshare.com/wiki/E-Paper_ ... iver_Board) together with a Waveshare 2.13 inch display. The board works nicely with the example Arduino code from Waveshare.

However I wanted to use esp-idf with the epaper.h library, but I can't get it to work.
I can compile and flash my program, but it seems that BUSY_PIN is always low => busy. Therefore the program loops in an endless loop.

I'm not sure if the GPIOs I got from the Arduino config and from the manual are correct.

Here is my Config:
#define MOSI_PIN 14
#define MISO_PIN 19 // guess not used
#define SCK_PIN 13
#define BUSY_PIN 25
#define DC_PIN 27
#define RST_PIN 26
#define CS_PIN 15

Does anyone have the board running? If so, what library do you use and how have you configured the SPI PINs?

Thanks in advance
Tobias
