I2C Scanner working on Cameras Grove Connector.
-
I managed to get the i2c scanner to work on the cameras grove connecter but still fighting to find the sensors.
Add the following to the bottom of Boards.txt in the Arduino>hardware>expressiv>esp32

and change
static const uint8_t SDA = 21;
static const uint8_t SCL = 22;to
static const uint8_t SDA = 12;
static const uint8_t SCL = 13;recompile and upload and it should now detect any i2c devices connected to the grove connector.
