Two I2C channels using the ESP32

Postby lenhalio » Mon Jun 10, 2019 2:18 pm

Is it possible to create two separate I2C channels using the ESP32 module?

There are two I2C controllers on board of the ESP32, each of which can be set to master mode or slave mode.

These answers are easy to find if you read the docs!

Excellent.....that is what I had hoped for but some posts indicated that there was only one I2C controller per ESP32. Thank you.
