• The SD card module works on ESP32. Great!

    Does Espruino support SPIFFS file system now on ESP8266/ESP32 ?

  • No, that has not been implemented.

  • Please can you post your wiring and script you used, as @jumjum was trying to get that to work and did not have success.

    Hi, do you mean codes using SD card on ESP32? or SPIFFS file system?

  • @user73896
    I mean the javascript you used to get the spi SD card working, and the wiring and pins you used - perhaps even a photo!
