Does anyone know of a standard example piece of PRU code that acts as an I2C slave?
I'm wondering if there exists some standard piece of PRU code that acts as an I2C slave? I'm working on the DA810, which apparently uses the PRU as an I2C slave driver (dMAX) but no source is provided.
Of course the source for the dMAX code on the DA810 would completely solve my problem if anyone has that!
I'm looking for this as I want to improve the handling of an error condition. The I2C clock can get stuck low if the DSP does not service the PRU in time.
