Editing 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 am recording some experiences playing with pic pack.

Page Not currently linked into Open Circuits will do so later, when more complete.

I 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.  This guide will have links in order for each section.

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

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).

*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?

* 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.

It is late, good night for now....

Ok, reads fine.

== [http://embeddedadventures.blogspot.com/2008/04/8-its-about-time.html Part 9. It's about time -- 14 April 2008] ==

Just reading:

''There’s the serial handlers, as usual, but also the timer_handle_0_isr() routine – which takes care of timer 0. Note that in your code somewhere, you need to include a routine called timer_0_callback() like this:''

Why do I need the timer_0_callback() is it because the call is imbedded in timer_handle_0_isr() -- and if so how did you compile without it?


 test_tick = tick_get_count(); // find out what we're up to
 if (tick_calc_diff(tick_marker, test_tick) >= 1000) { // 1000 - it's a second
       serial_print_str(" "); // print something out
       tick_marker = test_tick; // reset to find next 1000
  }

fix formatting

find out what we're up to is this a pun meaning find out what count the pic_tick is up to ( on timer0 ) ?

is the intent of this to ignore the time it takes to print? will this do it every second or pause 1 second between prints?

what is the data type of test_tick, I guess I could look at the header file.  Why does it work even if it wraps around?

read it seems fine.

 covers i2c protocol itself   -- interesting but do not have this device 


rest read ok,   -- did not open sample code, need to go back and do this.

read just a discussion of various pics, which left out the 16f877a one of my favoriates.
