ESP32-S2 - ULP & i2c communication
Hi! I'm interested in communication over i2c from ESP32- S2 ULP RISC coprocessor. Can I use ANY GPIO for i2c communication? Or I must use only certain pins. I heard that ESP32 ULP coprocessor had some certain pins for i2c communication and it isn't possible to use any GPIO. Thank you very much, David.
