Need a PIC18 chip with more memory, I'm using the PIC18F4685 with 96Kbytes of program memory.
Still not working. Might be software or hardware, I'll need to check it on a digital oscilloscope.
Correct clock rate (less than 400KHz).

Will be useful for future projects, however the included processor, the PIC18F4550 does not have enough memory for the filesystem library from Microchip.
