I have finished writing the required code and have converted it to a hex file but now I have come across a second problem.
As I don't have a programmer for the module I can't find a way to write the hex file to the flash memory in the module.
I have an atmega16(might need an atmega32 or higher but its pretty much the same thing) but no hardware description or schematics that might help in programming the flash using the atmega16. If you could give me some pointers I'd be very grateful.
I've tried looking for other options but somehow they've eluded me completely.
Another option if possible is that I could use the rs232 combined with an interface (a level shifter and charge pump) to transfer the hex file directly from my computer to the module, provided there is a software which can do just that.
Is this or the previous thing possible, if yes I would really appreciate all the help I can get.
