Development hardware

[KRavEN]

I have my reefangel running on my tank and I want to work on some custom code for it. I don't want to test/develop on my RA unit because it's busy doing it's job. I would think it should possible to piece together a hardware development kit out of standard arduino hardware. I have a mega1280 and nokia lcd shield I was using for krusduino before I went with the reefangel. Would there be any big changes to the libraries to support a standard mega1280 or mega2560 board? Has this been asked and answered before but I'm just not finding it searching the forums and google?

Yes, you can do that.
You may need to remap the pins on the libraries though.

Sounds like fun

I've been digging through the libraries today. I see a lot of "#if defined(__AVR_ATmega2560__)" statements. I'm betting I just need to add OR __AVR_ATmega1280__. AFAIK the only difference is one has 128k flash and the other 256k. They're pin compatible even.

For the NokiaLCD, using software SPI makes it much easier. I had modified the nokia 3310 library a while back to get the hardware spi working on the mega and that was a bit of a pain.

Any additional tips? I'm thinking now that I should have opened this thread under the hardware or libraries forum.

Correct. They are the same thing and pin compatible.
The hardware spi would have made the LCD run a little faster, but software spi works fine too.

Now if there were an easy way to convert from 128x128 display setup to 84x48 nokia 3310 display I already have I wouldn't need to buy a 6100 breakout board.

I think the initialization code is different, but other that that you should be able to draw your own screen
