Believe it or not I am thinking of developing a project on an SX48. I have a need for multiple UARTs at high baud rates, and you just can't do that on a PIC. The only dual UART PICs are high pin count monsters, and that isn't very appealing either. PICs, of course, don't have the speed to do it by bit-banging, but the SX certainly does. So, just what do I need to: 1: Do in-circuit programming 2: Do in-circuit debugging 3: Develop in assembly language Finally, are there any assembler choices that would allow me to use mChip style assembly mnemonics to develop for the SX?
