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 unlimmited 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 googling this is the only good reference I can find, not entirely sure what it means so far.

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....
