I'm using UART2/baud=115K+ with a DMA channel(2&3) as interrupts can be turned off for some period of time ~1mS.
I'm expecting an async packet in over UART2, variable size say 60-512bytes,
Is there a way of creating a packet timeout - no characters have arrived on UART2 for 50char timings.?
KL25P80M48SF0RM describes 4 standard DMAs and looking to see if I can possibly connect a timer in parallel and generate an INT when no char received,
Are there any AppNotes for connecting KL25 UART to DMA?
