Hi,
I bought a WeActStudio 2.13" Epaper and I connected to an ESP32 following the example reported in GitHub. It works fine and displays data collected from temp and hum sensors and a timestap from RTC DS3231, both connected through I2C.
After some minutes of deepsleep the ESP32 awakes and the display refreshes.
I've tried to add a SDCard module that is connected through SPI and after many trials I succeded in getting the SDcard work BUT the display doesn't refresh.
In serial monitor the values for Power-On, Full-Update and Pover-Off are completely different from those that appear when the Epaper works AND the SDCard is not connected.
The SDCard works with these connections: MOSI to pin 23 (shared with SDA of Epaper), MISO to pin 19, SCK to pin 18 (shared with SCL of E-paper), CS to pin 16 (defined in the code) .
I'd be very grateful if you could help me to use both the Epaper and the SDcard
