im using this DC Motor Driver HAT https://wiki.dfrobot.com/DC_Motor_Drive ... KU_DFR0592

I want to track the exact rotations. (Preferably via the tick count of the encoder than via the I2C RPM value.) ;)

1. Is there any undocumented register to get the encoder tick count?

2. Are there any source for the STM32 to modify the standard firmware?

Thanks in advanced.
