The ESP32 appears to use esp32-hal-i2c.h for the error codes, but the Cubcell appears to use all sorts of weird things for i2c. There is something custom for every sensor? Do I need something custom for the cryptochip? see; https://github.com/bshambaugh/heltecesp32andCubeCell_Wire/

How do I set the I2c speed?
I solved the problem. I it is described here: http://community.heltec.cn/t/debugging-faulty-cubecell-i2c-connection-to-cryptographic-authentication-chip-atecc508a/2300
