Firmware...

I have my gen7 board completely built and working so far, and I believe I just burned the bootloader to it. I'm having trouble with the firmware now, however.

I tried Teacup, but I'm not sure I understand the instructions. I downloaded the .zip of all the teacup files, extracted them, then downloaded the config.h.FiveD_on_Arduino file, but am not sure what to do.

I followed the Teacup instructions and copied config.h.FiveD_on_Arduino to the config.h file (CP config.h.FiveD_on_Arduino config.h), then opened the Teacup Firmware file with the Arduino IDE (It wanted to be put in it's own renamed folder, so I had to move everything else into this folder or the file would be blank when opened).

I tried to compile and upload, but I got an error compiling:

In file included from clock.c:7:
/pinio.h:42:20: error: macro "power_off" passed 1 arguments, but takes just 0

Am I even trying to do this right? Is there any official gen7 firmware that I can just open with the Arduino IDE and upload to my board?

No, there is no firmware specific for Gen7. Teacup and FiveD should work with the pin assignments adjusted.

config.h.FiveD_on_Arduino is out of date, unfortunately. Try the one I attach here, it should be at least sufficient to compile and move the motors.

I think it works...

I copied the contents of the file you provided and replaced the contents of config.h.dist using a text editor (This is correct, yes?).

I got an error compiling stating that the config.h file could not be found, so I put the file you provided into the teacup_firmware directory, and it appeared to compile correctly....going to upload shortly...

Edit: Ah, I'm stupid (And sleepy). The config.h file is what is actually used, the rest are presets that need to be copied to config.h

So everything I just did was correct... (right?).

As soon as I can get the drivers for my ftdi to usb breakout board, I'll try uploading to the ATmega.

Oh, another thing I'm unsure about (sorry). The bootloader I uploaded to the board was the "Gen7 with 644p and 20mhz".

But in the Makefile, it states

# CPU clock rate
F_CPU = 16000000L
# F_CPU = 8000000L

Should I change F_CPU = 16000000L to 20000000L? Or is changing anything else unnecessary as long as I have "Gen7 with 644p and 20mhz" selected under the arduino IDE?

Arduino IDE ignores the Makefile, so it doesn't matter what you set there when using the IDE. If you upload with "make program", you should indeed set F_CPU to 20000000L.

Actually, this number should match your crystal. Component Kits delivered by me come with a 20 MHz one, many others use the more standard 16 MHz version.
