Hi everyone,
Could I use the DMA controller to perform a reading on a MASTER SPI?
Setting the source address of the DMA channel and TD as the pointer to the RX data buffer of the spi, I do a reading of the buffer contents, while I need to perform a new reading.
There is a way to do this ?
Thanks in advance for any suggestion

I think you can have a try, and see the CE62153(psoc3/psoc5-16bit ADC data buffer using a dma) and AN52705(getting start with DMA) for reference!
May you succeed!

I have attached an old SPI-DMA project. This was originally available on cypress website. You might have to upgrade the components to the latest revision for them to work.

And of course to understand DMA you can use the App notes that have been referenced above.
