Starting Off

Pic Pack is an interesting library of PIC C code for BoostC and has an accompanying set of tutorials. I can be found using the links below. I have wanted to try it out for a while, here is my experience ( so far )

Author russ_hensel

I recording some experiences playing with pic pack.

Not linked into Open Circuits may do so later.

could not find beginning of blog, best I got was part 13, googling let me find welcome finally got the archive for 08 to open,

I am using BoostC 6.90 unlimited non-commercial on a pretty much up to date XP system

First 4 parts

07 April 2008 -- 1. Introduction

07 April 2008 -- 2. Microcontrollers

07 April 2008 -- 3. Take your pic

07 April 2008 -- 4. Compilers

Make sense to me, just read them.

07 April 2008 -- 5. Your first pic program

Notes from: Jan 11 2009

  • text said: adventures\flasher: try instead: demos\flasher think this it was moved.
  • no mention of target, i left it at: 16f88 ( target is part of the project, so of course it was right for the text.
  • I tried to build, IDE said building... but then nothing? I am using 6.90

tried compile and got error locating the compiler, so I pointed the IDE to mine. Problem was I do not keep my compiler in the normal location, all users shuld check this setting if the build just seems to hang.

  • Then had error finding: C:\Source\Electronics\MicroController\Pic\PicPack\demoCopy\flasher\flasher.c(7): Unable to open include file: pic_utils.h

This is because I had moved the project, need to keep the relative locations of... demos and ...pic_pack_lib unchanged so I put a copy in the right relative location.


  • Now compiles successfully.

but got the warning

#ifndef GOT_CLOCK
	#warning "Don't know about your clock. See pic_utils.h"
#endif	

This seems to be related to lack of definition of PLATFORM_CLOCK == 12000000. Perhaps this is what should be in flasher.c instead of ( or in addition to ) #pragma CLOCK_FREQ 8000000 Or perhaps it is just a warning to be ignored.

  • note that
   /*
  
   */ 

in the code denotes a comment ( and that the contents is ignored by the compiler).

08 April 2008 -- 6. Chip Programming

  • I am going to try an 18f2550 so looking up the configurations setting for it.

I am confused about config1, 2.... and the high and low so how do I read the .h file? Seems that for the 18F2550 we need

_CONFIG1L,  _CONFIG1H,   _CONFIG2L,   .... 

this seems at least to compile .... but the linker fails with

Error: .obj or .lib file wrong target type
Error: Failed to process:pic_utils.obj

Perhaps i am still missing some sort of config or #define switch. But no problem fixed by removing all but ._c .c and .h files and recompiling, changing target from 16F to 18F was probably the problem.

Putting in the configuration took me a long time, 16 config locations. Not sure I have them right, perhaps if I copied a configuration from some bootloader that worked on my chip?

08 April 2008 -- 7. Bootloading

  • I do not want to use 16f88, I do not have one, I will use either the 18f2550 or if I have to the 16F877 which I have a lot of, and have used a lot.


Good night for now....
