Hi,
Below is a led flasher .hex code to test your board with, it runs fine on my 2550 chip.
PortA are inputs, B and C are all outputs and it uses it own internal oscillator to flash all of PortB at 1 second intervals, so no need to worry about your crystal connections.
You can use a led on the output/s via a 330r resistor or simply measure the pins with a voltmeter to prove your chip works.
The Config parameters are built in to the code, but if you have to manually enter them on your programmer these are essential changes/basics, though these are in Assembler layout.
CONFIG FOSC=INTOSCIO_EC, WDT=OFF, PWRT=ON, BOR=OFF, MCLRE=OFF, LPT1OSC=OFF, XINST=OFF
CONFIG LVP=OFF, VREGEN=OFF, PBADEN=OFF, DEBUG=OFF
Important mod you need to do on your board, any chip you use should alway have a 100nf capacitor across its + and - pins .
Particularly important on the Pic and place it as close to the chips pins as possible.
