I have some problems using UART-DMA. I am communicating two boards by PC through the same RS485 line.
1) In this case can I vary the number of bytes while transmitting and receiving? If so please exlpain how it can be done.
2) DMA is disabled after an interrupt. can we use DMA without re-enabling it everytime like UART interrupt which automatically interrupts the controller when one byte is received..?
