AM6422: ADC DMA

wanglili 王
Intellectual 330 points
Part Number: AM6422

Tool/software:

Hello，

  We now want to use the R5F core of AM6422, use the ADC inside the SOC to sample, collect through DMA, generate a DMA interrupt after a certain time, and then process the sampled data in the sampling buffer. The sampling interrupt time can be set according to actual requirements, so Can this be achieved? The SDK we are currently using is 8.6. If so, are there any relevant reference cases for us to use?

  At the same time, we also want to use another scenario. How to trigger R5F to work and sleep in low power mode? Do you have relevant information that can be used as a reference in this regard?

    Hello wanglili,

    I am helping for ADC query on this  thread and please raise new thread for low power modes queries since I am not aware of this topic and other experts comment on this low power modes support.

    Exactly the below example is matches your requirement and use it in your application .

    Please let me know if you face any issues .
