More information
If I use M5Unified.h and then a begin of M5.begin(), the data is all zeros. If I take out the begin, then the data is correct. There must be something in the M5Unified that is restarting the Wire or taking over the I2C bus.
How can I correct this. It is a show stopper. If I can find a solution, then I will have to discard the M5Stack basic and go to a regular ESP32.
