Don't know what's wrong!

Hi Ioannis,
Well the program is an example provided with the software compiled for 628A (I believe):
loop:
High 0 ' Turn on LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds
Low 0 ' Turn off LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds
Goto loop ' Go back to loop and blink LED forever
End
And the schematic is simple and the circuit works fine with “readymade” code so I guess its ok.
Thanks.

So that's the code that works. Can't help you with that...'cause...well...it works...

Post the code that doesn't work... Make sure it's compiling for the correct PIC, make double sure you're not compiling for, say, the 16F628, when you're actually programming a 16F628A, or something like that.

Hi skimask,

No, that’s the code I try to get to work!
I compile it in MCS (no fault messages) for 628A which is the one I got but it does not run. The code I run successfully is a hex code which I can’t change nor se how it is made “inside”.
I run my 628A on its internal oscillator in both cases.

Thanks!

If you have not changed the 16F628A.inc then I bet it is trying to use the XT OSC.
Look at the link I sent before and the data sheet for the correct setting when using the internal OSC.

It will be something like INTOSC instead of XT.

Hi Dave,

How does the compiler pick up the *.inc file and where is it originally placed. In assembler there is an “Include” command but in PBP there are not as far as I have seen.
I will have a look at the PIC datasheet and the link you supplied, thanks!

[mackrackit]

The *.inc is in you PBP directory.
When you compile with Pic Basic it will automatically look there. Or you can do it in your code.
The link tells how.

Look at the ASM file made after you compile and you will see the includes.

Ohhh...ok...I get ya now...
Make sure your MCLR is pulled high regardless of the config bit settings and try it again, except instead of waiting a second for the LED to blink, wait for about 2 minutes.

If it blinks in 2 minutes instead of once per second, the PIC is running on the low speed internal oscillator (32khz - 48khz depending on which datasheet for the 628A you look at) instead of the high speed internal oscillator (4mhz nominal).

If that's the case, then, as stated before by others, do a bit of searchin' and learn how to play with config's and fuse settings.
