@m5stack Thank you for the answer! The example for the IMU works. The SD(esp32) example does not work on my M5Stack. So far I haven't found a way to save the data (using the command M5.IMU.getAccelData(&accX,&accY,&accZ);) to an SD card. Do I have to convert my data into a string to save it in a txt file or can I save the data directly as float variables? I also wanted to know if there is a command to display the acceleration data directly as a graph on the M5Stack display (and not just the value)?
