Epdiy wiki

At the moment the only existing documentation is on epdiy.readthedocs.io Please have a nice read over there. I will research on how to make a sync (if possible) between readthedocs and this github Wiki.

• If possible the sync should only overwrite pages with the same name
• Letting us generate special pages with more in deep technical info or test for Boards, Displays, etc.

epdiy V7

Branch: s3_lcd Color experimentation: s3_color_research

How to build the Firmware

Make sure to let idf know you will use the S3 target MCU. IDF required version: 5. For Linus I add this after setting the IDF_PATH in .profile

alias prep_idf="source $IDF_PATH/export.sh"

Then you can simple type prep_idf in the console so it calls automatically export.sh and then you can simply type idf.py to access the IDF toolchain.

idf.py set-target esp32s3

Configure the menuconfig selecting the right epdiy driver Board (V7) and the epaper you are testing

idf.py menuconfig

While there, make sure you enable PSRAM (Octal for this board)

Component config --> ESP PSRAM --> Enable SPI-connected RAM --> Config --> QUAD/OCT

Additionally: Set RAM clock speed (80MHz clock speed)
