RS485 SAM4S

Tue Jul 21, 2015 4:17 pm

Anyone familar with the RS485 interface on the SAM4S.
The receiving works perfectly but when i want to transmit something the D- line always remains at zero. The RTS line is (how it is also written in the data sheet) during the transmission high. The CTS pin is set high during the transmission. Still doesnt work. Thanks in advance
