There is an I2C interface available on the Colibri module.

Toradex provides an simple Library to access the I2C unit.

In the standard image, this interface is also used by the RTCSync tool. To avoid conflicts in the I2C register accesses, the RTCSync can be disabled or a mutex can be used.

Disable RTCSync

RTCSync can be disabled by renaming the key value in registry.

Using a mutex

The name of the mutex used for I2C accesses is "I2C".
