Do you have PortB set as output? You need TrisB.3 = 0 in your code.

well I didnt, but even with that code at the top it does not work

What config settings did you use?

What PBP version do you have?

PM or MPASM assembler?

How is your led connected, and what resistor value are you using for it ?

If i remember right it is connected to the positive end, then the negative end is grounded, and there is no resistor. But I know that the configuration is correct

Technically, you're supposed to put a current-limitting resistor along with an average LED with 5 VDC; most use 330ohms. Does the LED still work on 5 VDC and a resistor? Confirming it isn't burnt is a good start.

Some overview on what files are used (I have v2.60, so it's about the same as 2.50 - the syntax for 16F is just a bit different):

EDIT: Look at top right, try CONFIG 16F628A in Advanced Search.

the led works, and I have been told by 2 friends of mine familiar with what I am doing that I dont need a resistor because of my setup.

But even after reading that stuff I can still not get this working for the life of me. Here is my, still broken, code.

@ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN_ON & _LVP_OFF

Define OSC 4
CMCON = 7 
VRCON = 0 




PortA=0
TRISA=0000
TRISB = 0000 
PortB = 0000 


Main:
High PortB.3
high PortA.1
pause 1000
Low PortB.3
low PortA.1
pause 1000
goto Main

Also, I just found these fuse settings in my programmer, should one of these settings be different?

Robert

what is a config value?
2.5 if I remember right
