Adapting a PICAXE program to PBP, to program a PIC (compiler Errors)

[mpgmike]

It's been quite a few years since I played with PICAXE, but what I do remember is that to configure the TRIS Registers, with PICAXE an Output = 1, but with PBP an Output = 0; they're backwards.

Second, with PBP you configure PORT related registers with the PORT -- TRISA = xx, ANSELA = xx... With PICAXE you have a generic PORT register that covers pretty much every PORT pin in one fell swoop (OUTPUT 0, INPUT 1, etc.). In other words, there may be some major changes you need to make to your code.

I found when folks try to help me by handing me answers, I get past the immediate situation, even if I have no clue why the suggestion worked. When folks tell me where to find the answers myself, I can get past my current dilemma, but I then know where to look the next time I run into a challenge. May I suggest spending some quality time with the PBP3 Reference Manual, a free download from the ME Labs web site.

My personal journey started with PICAXE about 11 years ago. After about 2 years I upgraded to PBP3. I've since plunged into the dark side with MPLABX. My advice is to download the PBP3 Reference Manual and spend time learning the PBP way of doing things.

Hi MpgMike
Indeed, there are several peculiarities to take into consideration when switching from Picaxe (or Basic Stamp) to a Pic.
But they are well documented in the Reference Manual which I consult if necessary.

I personally avoid using the registers that handle i/O and Directions.

I write in clear text in my program, which is then very readable, definitions like this:
Output 0 : Symbol LED = GPIO.0 'Led - pin7 - Out0

In the case of my present application, it was a stupid error of inattention because, indeed, the Pic12F629 does not have an ADC contrary to the 12F675!
This indeed caused incomprehensible compiler errors.

Thanks.
