Hardware PWM (HPWM) Clairification on 18F45K22

[CuriousOne]

I've used it on 628A without any defines, just HPWM command.

I've used it on 628A without any defines, just HPWM command.

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

#ENDCONFIG

#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).
