Sharp Memory Display ESP32C3 RISC-V Compatibility

[dgiampetruzzi]

Hi, thank you for this amazing project. I need an information. I would like to use the ESP32C3 to control the Sharp Memory Display. I know I could not use ULP to trigger VCOM (I would use an external RTC for this function). In general, is the library to drive this display compatible with the ESP32C3? Thank you!

Hi, the underlying library is Adafruit GFX (https://github.com/adafruit/Adafruit-GFX-Library). I have not used a ESP32C3 before so I can't guarantee that it works. But it seems likely as the only necessary peripheral is SPI. The only way to find out is to try it. :) Using an RTC for the 1Hz signal is a good idea. Does the ESP32C3 not have a ULP at all?
