Howdy, I have a fair bit of experience in microchip assembly, having just completed an engineering thesis based on a PIC18F452, but I have a new project which will require a lot more sophistication than can easily be achieved using assembly alone. My question, which is probably a recurrent one on this list, is which of the several C compilers should I be looking at. My criteria are inter-operability with mplab, quality and quantity of libraries and of course cost. Any advice would be greatly appreciated.
