Expand description

Set a hardware peripheral as the source for a DMA transfer

hardware_source is expected to be a pointer to a peripheral register that can provide DMA data. This function configures the DMA channel always read from this register.

Safety

Caller must ensure that hardware_source is valid for the lifetime of the transfer, and valid for all subsequent transfers performed by this DMA channel with this address.
