Hi everyone. I'm a novice so have patience with me. I have a stm32f103c8 (blue phill) card connected to 8 HC-SR04 ultrasonic sensors. I use the STM32Cube IDE. I already have the program ready to read the distances in all the ultrasonic sensors. Now I need to be able to communicate the STM32 card by i2c as a slave to a Raspberry Pi 3B + to send the information of the 8 sensors and I would like to know how to do it. I appreciate that you can guide me in this regard. Thank you. (My local language is Spanish so I use google translator to write the query, I apologize if you cannot understand my query well).
