ERROR Compling 16F819...l but the 16F818 works fine

I get an error when I compile for the 16F819... the same code works for the 16F818. Explaination?

Here's the error msg:
Error [124] C:\PROGRA~1\PICBAS~1.16\PBPPIC14.LIB [Illegal Argument]

Compiles fine for me on the 818 and the 819 (I use MPASM).

However, your troubles could be due to the “Return” at the end of the Blink section. Did you intend to use “Gosub Blink” instead of “Goto Blink” in the Loop Section?

Your suggestion of using "goto" did not work.

If you add -v to your command line when compiling, it should highlight the offending line during the compilation process to give you a clue where to look.

As Paul said you should be using GOSUB BLINK because you are calling a subroutine, and not GOTO BLINK as in your original post, which makes me suspect that the code you posted on the forum is not exactly the same as the code you have in your working program, because you will get a Stack Underflow the instant your try to run it on a PIC.

------ I should have stated I am using the complier that comes with PidBasic Pro called MicroStudio, so I don't know how to do the command line option you suggested. Thank you though ----

I have tried both "goto and gosub" with same result... I'll try again this morning and see what I can get! (fingers crossed)

It's probably a setting in your Microcode Studio (which I don't use). The reason I say that is that the only difference between a 16F818 and 819 is the memory. PICBasic will not give you a clean compile on the 818 and then an error on the 819. Sometimes I think IDE's give you more problems than they're worth.

Eveybody can have their own opinion about any IDE but in this case it's not the problem source. In fact, since i use MicroCode Studio i'd never ever have a problem related to the IDE when compiling the code, using the Serial Monitor, Bootloader or else component of.

NOW, let's see where it may crash...

Code:

---

ADCIN PORTA.1, X

---

Come on.. read carefully the PBP manual, you must write the channel number not the PORT PIN name

Code:

---

ADCIN 0,x

---

true about the Goto Gosub, you must write as

Code:

---

Pause 50
If X > 100 Then
        GOSUB  BLINK
        ENDIF
GOTO LOOP

---

BUT, i also suspect of a corrupted file in your PBP folder. remove PBP then reinstall it.

That's definately NOT an IDE problem. Work here with PM and MPASM with both PIC EVEN if i keep the Goto instead of using the GOSUB. I'll keep my own 'flames' about IDE.

Well the following code got rid of that strange error... now the LED blinks no matter what the variable number is. So another issue to tackle... whoa is me.
