from what I see, when HAL_GetTick() is called, it always return zero...

but on // I don't understand what cause the encoder not to success the readRegister(ENCODER_ANGLE_REV_REG)

only on s42bv2 hardware (works on s57bv2)

Hmm... try building the firmware with the 72 MHz system clock. See if that fixes the issue. Sometimes the 128 MHz clock is actually too fast for the silicon of the STM32... it was never meant to be able to clock that fast. It actually tells you not to, but I haven't had any issues so far and it has a major speed improvement over 72 MHz.

Sorry for the delay in responding, I just returned from Spain
