Forgot to add this - Flowcode uses macros to turn your flowcharts (built in a GUI very much like a schematic design tool) into C. The C is then compiled to the HEX, which you then program using your preffered tool. I've just used it to build a SMART battery charger and calibrator, where I needed to do alot of I2C communications. Finished the first versions in two days.

Flowcode for PICs is the best! You can write code for them using simple flowcharts.
