I used ASF to set up a project where I use the FreeRTOS USART library.
However, I don't see any way to set it up to use RS-485.
I believe I'm supposed to use the API freertos_usart_serial_init(), which takes a parameter of type freertos_peripheral_options_t.
Within those options, there is a field for operation mode, and the options are:
I believe you could set it up as RS232 (that's what the SAM driver does), but later on you need to set the RS_485 flag.
Should I just go around the driver to set that 485 flag?
