I am brand new to all of this, so I apologize upfront if this is a really basic question. I wired a USB FTDI cable to my atmega2560 board and I can't upload sketches. It keeps timing out. When I connect RX, TX and GRD at 115200 baud rate, I can see messages from the board. As soon as I connect the RST (and the CTS) cable, I stop getting messages. As I understand it, I need RST in order to upload sketches. Here is how I currently have it wired:
5v (left disconnected)
Here is the cable:
The board is powered separately, so I figured that I shouldn't connect the 5v wire. Since I don't have a CTS pin, I connected CTS to GRD (I read this tip in a forum thread). It seems like no matter what I do, I can't get proper communication after introducing the RTS wire.
I searched these forums for a few hours with no luck. Any help is appreciated.
