Hello,
I'm trying to implement serial interface with the lowest possible processor load.
Should I use DMA or Interrupts. If interrupts are the option, how do I implement handler on data receive event if there's no IRQ handler available for the user in UART DAVE APP.
There's only event on successful receive declared number of bytes, but how would I know, how many bytes to receive? I don't want to check if there's data in buffer in a loop, like it's in all exaples.
