I have a LED matrix with 140 LEDs that I would like to control using Flash (Firmata+AS3Glue) and the Arduino Mega. I initially tested a small matrix using the Duemilanove, and it worked perfectly. However, as soon as I tried plugging in the Arduino Mega in its place, it wouldn't work at all.
I did some researching, and apparently Firmata does not fully support the Arduino Mega. I saw a few posts where people mentioned the Firmata from the Maxuino website works, but I could not get it to compile due to this error:
'TOTAL_PINS' was not declared in this scope (line 34)
I am considering using a language other than Flash, or something other than Firmata to get around this problem, but I have not found any alternatives.
I need to have a graphical user interface, where the users select through the software which LEDs they want to turn on/off. With that in mind, I have no choice but to use a high level language to communicate with the Arduino, be it through Firmata or any other option.
If anyone has any suggestions or ideas, it would be greatly appreciated. Thanks.
