Playing With PIC Pack
Contents
Starting Off
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 unlimmited non-commercial on a pretty much up to date XP system
First 4 parts
Just read them.
5. Your first pic program
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
- ifndef GOT_CLOCK
#warning "Don't know about your clock. See pic_utils.h"
- 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
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
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.
