vPIC

A work in progress Microchip PIC microcontroller emulator.

Currently emulates the 12F508, all 33 instructions decoded, almost all instructions are emulated but there several important features missing!

Here it is running:

MOVLW 1
MOVWF 10
MOVWF 11
MOVF 10, W
ADDWF 11, W
MOVWF 12
MOVF 11, W
MOVWF 10
MOVF 12, W
GOTO 1

After 87 cycles the state is (generating the fibbonachi sequence)
