Web6 mei 2024 · I'm suspecting that it might be an issue of clock timing, since the STM32 is running at 72MHz and I assume capable of faster throughput than the 16MHz arduino. Then again, if I understand it correctly I2C conforms to a standard 'high' speed of 400kHz to allow compatibility across many devices.
