Ok the problem is that I want to do is Enable UART1_RTS. But I do not know how to configure it to On when I write something using RS23s. After UART I have RS232 to RS485 converter. And I need this pin to Enable the sending.

Hi David,

You can find an example for configuration of the UART1 in the TRM - chapter 7.5.4 - "Pad Configuration Programming Points" at the link:

Hi,

Sorry but the link is for "AM/DM37x Multimedia Device" I don't know if it is the same for ARM 8 am3517. And chapter 7.5.4 in this document is "7.5.4 DSI Protocol Engine Basic Programming Model"

Thank you
