(Incidentally, the Serial Port menu is greyed out). All of the issues I've seen posted on these forums regarding serial communication seem to have already gotten past this step (they've been able to actually get some kind of communication between the Pi and Gertduino) so I couldn't find much to help me troubleshoot. I have edited the two files (cmdline.txt and innitlab) as described here. However, I'm not familiar with Python so I'd prefer to use the Arduino IDE to communicate over serial rather than a Python script, at least for now.Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?
Do I need some sort of additional driver to be able to connect via RS232? I did see that normally with an Arduino connected via USB you have to install certain drivers, but since the Gertduino doesn't use the same FTDI chip (and it uses RS232 rather than USB) I couldn't find any suitable drivers from some quick searches.
Also, once the 328 is programmed, do I still need the jumpers in place as described in the Manual on page 6 for GPIO programming if all I'm doing is reading and sending data over RS232? I'm currently using the provided jumpers (along with two male-male jumper wires) to cross-over the RX-TX pins.
Finally, is there any easier/"better" way to receive/send packets of data from the Arduino, whether it be with the Arduino IDE or avrdude or whatever else? Thanks!
