I am doing a project with Arduino Due processor, the Atmel SAM3X8E, I will use the 100 lead version to do my own board.
For the serial comunication I will use both native USB port and programming port, for the programming port I will use the FTDI FT232RL. I have no problems with the native USB connections.
I am having troubles trying to figure out the necessaries connections between the FTDI and the processor.
Do I need the CTS, RTS and DTR pins from the FTDI to connect to the processor? Or only the DTR for reset while downloading code from the Arduino IDE?
Hope someone can help me, because I dont´t see anyone using the FTDI FT232RL with this processor.
