Maybe somebody have library for CH201 ultrasonic sensor?

Hi @RGudo.1​ ,

since the CH201 ultrasonic sensor is from TDK-Invensense, I would suggest you to check their site (for example the documentation page) ;)

Hi @RGudo.1​ ​, did you manage to get communication with the CH201 sensor? We have taken over the functions from the chirp sources, but I see my I2C gets stuck (infinite clock stretching) when accessing the sensor in programming mode. Since the chirp example is really low level in the I2C interface I wonder if you succeeded using the STM HAL functions for I2C?
