    The 16F628A only has one CCP module, and it's output cannot be moved to a different pin.

    The 18F45K22 has 5 CCP modules, and two of them can be moved to different pins.

    The part that was most helpful is the fact that PBP3 now defines all of its config bits in a very organized fashion for the new devices:

    #IF __PROCESSOR__ = "18F45K22"
    #MSG "** STARTING FIRMWARE COMPILATION **"
    #MSG "COMPILING FIRMWARE (" + __FILE__ + ")"
    #msg "FOR MICROCHIP PIC PROCESSOR (" + __PROCESSOR__ + ")"
    #IF __LONG__ = 1
    #MSG "PICBASIC COMPILER IS USING LONG VARIABLES (PBPL)"
    #ELSE
    #MSG "PICBASIC COMPILER IS USING WORD VARIALBLES (PBPW)"
    #ENDIF
    #CONFIG
    CONFIG FOSC = INTIO67 ; Internal oscillator block
    CONFIG PLLCFG = OFF ; Oscillator used directly
    CONFIG PRICLKEN = OFF ; Primary clock can be disabled by software
    CONFIG FCMEN = OFF ; Fail-Safe Clock Monitor disabled
    CONFIG IESO = OFF ; Oscillator Switchover mode disabled
    CONFIG PWRTEN = ON ; Power up timer Enabled
    CONFIG BOREN = SBORDIS ; Brown-out Reset enabled in hardware only (SBOREN is disabled)
    CONFIG BORV = 190 ; VBOR set to 1.90 V nominal
    CONFIG WDTEN = ON ; WDT is always enabled. SWDTEN bit has no effect
    CONFIG WDTPS = 32768 ; 1:32768
    CONFIG CCP2MX = PORTC1 ; CCP2 input/output is multiplexed with RC1
    CONFIG PBADEN = OFF ; PORTB<5:0> pins are configured as digital I/O on Reset
    CONFIG CCP3MX = PORTE0 ; P3A/CCP3 input/output is mulitplexed with RE0
    CONFIG HFOFST = ON ; HFINTOSC output and ready status are not delayed by the oscillator stable status
    CONFIG T3CMX = PORTC0 ; T3CKI is on RC0
    CONFIG P2BMX = PORTD2 ; P2B is on RD2
    CONFIG MCLRE = EXTMCLR ; MCLR pin enabled, RE3 input pin disabled
    CONFIG STVREN = ON ; Stack full/underflow will cause Reset
    CONFIG LVP = OFF ; Single-Supply ICSP disabled
    CONFIG XINST = OFF ; Instruction set extension and Indexed Addressing mode disabled (Legacy mode)
    CONFIG DEBUG = OFF ; Disabled
    CONFIG CP0 = OFF ; Block 0 (000800-001FFFh) not code-protected
    CONFIG CP1 = OFF ; Block 1 (002000-003FFFh) not code-protected
    CONFIG CPB = OFF ; Boot block (000000-0007FFh) not code-protected
    CONFIG CPD = OFF ; Data EEPROM not code-protected
    CONFIG WRT0 = OFF ; Block 0 (000800-001FFFh) not write-protected
    CONFIG WRT1 = OFF ; Block 1 (002000-003FFFh) not write-protected
    CONFIG WRTC = OFF ; Configuration registers (300000-3000FFh) not write-protected
    CONFIG WRTB = OFF ; Boot Block (000000-0007FFh) not write-protected
    CONFIG WRTD = OFF ; Data EEPROM not write-protected
    CONFIG EBTR0 = OFF ; Block 0 (000800-001FFFh) not protected from table reads executed in other blocks
    CONFIG EBTR1 = OFF ; Block 1 (002000-003FFFh) not protected from table reads executed in other blocks
    CONFIG EBTRB = OFF ; Boot Block (000000-0007FFh) not protected from table reads executed in other blocks
    #ENDCONFIG
    #ELSE
    #ERROR "FIRMWARE NOT SUPPORTED FOR " + __PROCESSOR__
    #ERROR "FIRMWARE REQUIRES AN 18F45K22 PIC PROCESSOR"
    #ERROR "!!! FIRMWARE COMPILATION ABORTED !!! "
    #ENDIF

    This is the config coding i am using in my pic processor now. to set up all of the config bits and change the Mux'ing of the CCP Modules. The Code is also ver helpful because i program a lot of different devices and if i have the wrong device set when i go to compile it... The Editor will "remind" me to change the output device type to the correct PIC. Melabs has done a great job and creating more functionality in the newest versions of the compilers.

    Thanks Melabs for Being Awesome!!!

    How do you insert a "code" Block into a post so that the code doesn't loose all of its formatting?

    Use GO ADVANCED option below reply box. The CODE tags are with square brackets (icon is # sign).
