Hey all, new to the forum, I picked up a due and a 5" tft lcd display and I'm almost immediately running into a problem.
by itself, the Due seems to work fine, I can upload sketches, everything works fine.
if I connect the display, the computer can't detect the DUE, no Arduino found on COM3 messages. I can unplug the LCD,and then download a sketch, then plug the LCD in and hit reset and everything works. however if I hit reset again it appears that the sketch gets erased. I have to download again
I'm digging.. and I think I've found something, but need some guidance here: per the Due spec: Programming port: To use this port, select "Arduino Due (Programming Port)" as your board in the Arduino IDE. Connect the Due's programming port (the one closest to the DC power jack) to your computer. The programming port uses the 16U2 as a USB-to-serial chip connected to the first UART of the SAM3X (RX0 and TX0)"
well, the LCD display also uses RX0 and TX0 and I think what is happening is I might be hitting a situation where I'm getting the soft erase caused by the LCD resetting. I also think the fact that both are using RX0 and TX0 are causing me the upload issues.
any ideas? I'm going to dig some more but I'm wondering how hard it is to move the LCD to RX1 and TX1 aside from changing the pins which would be trivial....
