Steve,

Thanks for the reply. I've copied and pasted your code into a blank document and tried compiling. It errored with

Error [118] (path) : Overwritting previous address contents (0000)
Error [118] (path) : Overwritting previous address contents (0001)

Error [118] (path) : Overwritting previous address contents (0006)
Error [118] (path) : Overwritting previous address contents (0007)

Could you also paste your INC file so I can replicate exactly (or as closely) your files.

[mister_e]

I agree... you're rusty

check this

[malc-c]

Must be going senile too !

I can't see any device line in the INC file stored in the PBP folder

I've tried reming out the _config lines one at a time and that throws up other errors.
I'm pulling what little hair I have out

[mister_e]

O.K, you have two choices.

1. You rem all _CONFIG lines and set them in your code using the old way... well as i posted before

2. you rem all _CONFIG lines and you past those i posted.. so it should looks like

About now?

For sure there's no Device line for any 18F device. DEVICE is when you compile with PM, __CONFIG is when you compile with MPASM.

[malc-c]

Ok - I've copied and pasted the code over the original INC file (I did back up the old one first) - and removed the ASM part from the PBP code and it compiled fine.

On the breadboard RB0 is faintly lit and appears to be flickering slightly as I'm only getting +0.85v on RB0 - all other pins are low - also removing the Xtal seems to have no affect on the LED output, which to me would suggest that the timing is still not working ??

Taking pin5 (RA3/AN3/Vref+) takes RB0 low (with or without Xtal present) if that has any bearing on what is happening.

If I get chance I'll try and post a schematic of the basic hardware set up

[mister_e]

Kind of strange behaviour... it's working as suppose here. I suspect a faulty contact or a bad PIC first... well i think ...

[malc-c]

Well I've tried a new Xtal and PIC and I still get the same result, only the LED appears to be more stable (+0.58v)

I'll think I'll give up on this one...
