Hi

KL25 CW UART TX DMA is supported in the uTasker project : http://www.utasker.com/forum/index.php?topic=1721.0

However DMA at the receiver is not included since the KL DMA doesn't support free-runnning circular buffers - that is, it is not as useful as the DMA controller in the K devices.

Regards

Mark
