epdiy-esp32-epub-reader's Issues

SD card issue on S3

Still could not make it work with the SD card.

Maybe also bad hardware since I got the cheapest microSD from Aliexpress...

IO PINS:

 ; setup the pins for the SDCard
 -DSD_CARD_PIN_NUM_CLK=GPIO_NUM_18
 -DSD_CARD_PIN_NUM_MOSI=GPIO_NUM_16
 -DSD_CARD_PIN_NUM_MISO=GPIO_NUM_14
 -DSD_CARD_PIN_NUM_CS=GPIO_NUM_9

Error in Serial

Adding new board Cinwrite S3 with IT8951 epaper controller

Thanks to @jason
Let's use this Issue to communicate forward!

Next blocker for this: Either separate the IT8951 from epdiy since @atomic14 used this library as a base to keep the framebuffer. But EPDiy in this version does not support ESP32S3.

My wish will be to erradicate epdiy completely for IT8951 displays and instead use Lovyan GFX that supports IT8951. But that would be a complete revamp of the engine. And a cowboy should go slow and easy peasy to avoid falling of the horse ๐Ÿ‡
