TMS570LS3137: I2C and DMA

Part Number: TMS570LS3137

Hi

Is there an example on how to use and set up i2c with DMA ? 

I would appreciate your help.

Greetings.

  • Hello,

    Using DMA for I2C data transfers is not different than using DMA for SPI or SCI transfers. 

    A transmit event is generated after a START condition in master transmitter mode. The DMA receives data and transmits data based on receive event and transmit event. The read and write events have the same timing as I2CRRDY (I2CRINT) and I2CXRDY (I2CXINT), respectively.

    I don't have example for I2C with DMA.
