USART DMA use with H/W flow control

Hi All,

I would like to use DMA to service a UART that I am implementing (RX and TX). My project has 2 bi-directional data ports (including the UART) which have different data rates (up to 512kbps). I have to use hardware flow control on the UART (both RX and TX). Is this possible with the DMA method?

I have read through AN3109 and looked at the attached example code, but all examples have the hardware flow control set to "..._NONE".

Thanks in advance,

Charlie
