UART Tx with DMA

Hi, I'm developing an application requiring uart0 tx/rx with DMA.

Starting from example "low_power_dma_uart_demo" I was able to configure DMA (channel0) and UART0 and the receiving was ok (I don't need Low Power mode, so I've changed some setting with respect to the given example.

I'm not able, at the moment, to set the trasmission with DMA. Which are the steps to do? Do I have to use a new channel (channel 1 for example) and configure it for TX? I tried but without results.

Some hints? Examples? Thank you.
