At the beginning of Test.c I include the 18f65j90.h file but doesn't mention anything about periphals and that's why I get this error. Does this mean I have to include the p18f65j90.h or what?

The CCS compiler, is closer to a 'big C', in the way it handles I/O, than MCC, which behaves more like assembler in this regard. So (for instance), you would normally setup timer1, with a line like:
setup_timer1(T1_EXTERNAL|T1_CLK_OUT|T_DIV_BY_1);
as a complete single symbolic instruction, to setup the I/O, and divisors for this peripheral, rather than directly writing to the registers. the same applies for the other peripherals.
The include file, does 'know about the peripherals', but only as used with the CCS symbolic commands, not the individual names for every port.
You _can_ work directly like with MCC, but to do so, you need to load a register 'map', to give the symbolic names for the registers. Ones have been posted here in the past for the 16, and standard 18 chips, but I don't remember seeing one for the newer chips like yours. You would probably have to load the standard 18 one, and then define the extra registers yourself.

Thanks, I think you mean something like the following example that I found :
#byte PIE3 = 0xFA3
#bit TXB0IE = PIE3.2
#bit TXB1IE = PIE3.3
#bit TXB2IE = PIE3.4
but from where do I get the standard 18 register 'map' file ? |

Do a search for "register_list.h". This should find one that was posted for the early PIC18 chips. There may be other latter ones on the forum.

An include file for the PIC18F452 and 458 can be found in: http://www.ccsinfo.com/forum/viewtopic.php?t=14755
These files are easy to adapt/extend for your processor.
Another option is to use Chipedit.exe in the v4 compiler for generating a register include file. In Chipedit select your processor and then 'Registers / Make Include file'.
Chipedit.exe is downloadable from the CCS website in the IDEUTILS package (possibly the Command Line versions of the CCS compilers don't have download rights for this toolset?). |

Wow ckielstra, I had not discovered the ability of Chipedit to create the discreet register files, it works great...... I had been making these as needed all this time.
Looks like I learned another something new today!
Thank You! |
