This is one of my many Electronics Projects. This project is currently work in progress.
Most people write their microcontroller code using an assembler. I am a little different in that I write my code using a higher level programming language (in this case STIPPLE.) Basically, I have a libary of procedures, where each procedure corresponds to an opcode. I write a program that executes these procedures and the output of the program is both an assembler output listing and the final raw bytes to be programmed into the microcontroller.
Eventually, I intend to get around to implementing an emulator as well.
The source files are available.
