LP-AM243: DMA with the ADC

Dylan Tarter
Intellectual 320 points
Part Number: LP-AM243


Was an example of the DMA added to the MCU+SDK library? I haven't found it yet but I may have an outdated version. I am looking to add DMA for the on chip ADC so it can have a DMA buffer of ADC read values.

    Hi Dylan,

    There is a DMA ADC example in MCU+ SDK for AM243x 08.02.00.28 (it was temporarily removed from TI web site last week, will be restored in this week):

    mcu_plus_sdk_am243x_08_02_00_28\examples\drivers\udma\udma_adc_read (Also available in 08.01.00.36)

    And there are a few DMA with peripheral examples: 

    mcu_plus_sdk_am243x_08_02_00_28\examples\drivers\uart\uart_echo_dma and

    mcu_plus_sdk_am243x_08_02_00_28\examples\drivers\mcspi\mcspi_loopback_dma

    mcu_plus_sdk_am243x_08_02_00_28\examples\drivers\ospi\ospi_flash_dma (Also available in 08.01.00.36)

    Best regards,

    Ming
