      Thank you @ajb2k3 for the tip. That worked! I contacted the M5Stack technical support and not long after my firmware was included in the M5Burner.

      For those who are interested, the code at the end of this tutorial works well. The tutorial is about strings, but works in exactly the same way for base64-encoded jpg images. All you have to do after decoding the string (containing the base64-encoded jpg image) is to write it to SPIFFS and then call M5.Lcd.drawJpgFile(SPIFFS, jpgFileName, 0, 0);

      Currently there is no support for png images in the micropython port that form the firmware of the m5Stack range. BMP is its raw uncompressed state is a simple file to translate along with base level jpg (not JPEG!) Until such time that a codec exist for micropython, we are all stuck with converting graphics into base level formats.

      @m5er That is part of the problem, the ULP is not well documented and everyone is struggling with it

      Hello @AndyT hmm, strange, if anything I'd expected the M5Stack Gray to work with low brightness level and the M5Stack Black to not behave due to the fact that the M5Stack Gray has additional hardware (e.g. IMU) consuming power to keep the device powered on. That said, I suspect the IP5306 switching off due to too light load. Try to add the following statement before going into deep sleep. It should prevent the IP5306 from shutting down under light load. M5.Power.setPowerBoostKeepOn(true); Happy Stacking! Felix
