Has anybody used Memory DMA for reading data form Parallel ADC ?
Please share the Schemetic and Pseudo code ....
In order to perform Memory-to-Memory DMA (MDMA) operations for reading data from parallel ADC, you need to map that ADC in processor's memory space. We have one EE-Note (EE-321), which talks about interfacing AD7656 SAR ADC to BF537 through Async memory interface (EBIU) of processor. You can find it here:
This material you can use for your reference.
Unfortunately I am not ADC expert; so I am not sure if MDMA transfers can be used to read from this ADC. You can select the ADC which supports continuous MDMA transfers. You can take help from Data converter community for ADC related help:
You can find a simple MDMA code here, which you can modify as per your requirement:
