Playing With PIC Pack

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

part1

part2

part3

part4

Just read them.

5. Your first pic program

part5

Jan 11 2009:

said: adventures\flash try instead: demos\flasher think this is were it is now

no mention of target, i left it at: 16f88

said building... but then nothing? I am using 6.90

tried compile and got error locating the compiler, so I pointed to mine, problem was I did not keep mine in the normal location, all users shuld check this setting

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

Now compiles successfully.

but warning

1. ifndef GOT_CLOCK

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

1. endif

seems to be related to lack of definition of PLATFORM_CLOCK == 12000000 perhaps this is what should be in flasher.c instead of #pragma CLOCK_FREQ 8000000

or perhaps it is just a warning to be ignored.

note that

   /*
  
   */ 

denotes a comment that is ignored by the compiler.

6. Chip Programming

6. Chip Programming

I am going to try an 18f2550 so looking up the config 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

Problem fixed by removing all but ._c .c and .h files and recompiling, changing target from 16F to 18F was probably the problem.

This took me a long time, 16 config locations, not sure I have them right, perhaps if i copied from some bootloader that worked on my chip?

7. Bootloading

7. Bootloading

do not want to use 16f88, do not have one, 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....
