I am trying to set up SPI as a master using DMA. Which once should I use, DMA_LDD or DMATransfer_LDD? I have an external device sending a block of data. That device does not send data until I send an initiating command (SPI or GPIO).

 

I have PEx v10.2 with update.

 

I also see that starting with PEx v10.3 there is a new LDD Component, "DMAChannel_LDD". What functionality does that new device provide over DMA_LDD and DMATransfer_LDD? This is not mentioned in the release notes.
