PPS understanding on 16F15313

[richard]

looking at PBP3_PPS_NOTES for ccp i see no mention of seting ccp inputs at all, its outputs

reassigning ccpx inputs will be a manual effort

the dt_ints-14 will not work in standard form , all the ccp ints are in pie/r 6

i would just insert a new int to the file

  #define CCP1_INT     PIR1,CCP1IF, PIE1,CCP1IE    ;-- CCP1 
  #define CCP2_INT     PIR2,CCP2IF, PIE2,CCP2IE    ;-- CCP2 
  #define CCP3_INT     PIR3,CCP3IF, PIE3,CCP3IE    ;-- CCP3                *
  #define CCP4_INT     PIR3,CCP4IF, PIE3,CCP4IE    ;-- CCP4                *
  #define CCP5_INT     PIR3,CCP5IF, PIE3,CCP5IE    ;-- CCP5                *
  #define CCP1_15313_INT     PIR6,CCP1IF, PIE6,CCP1IE    ;-- CCP1

Richard,
Thanks, I'll work on it again tonight and update as I sort it out.

btw, thanks for taking up the torch around here. It probably seems tiring helping all the time, but it is appreciated.

Other than adding the define, is there anything else that needs to be addressed in DT_INTs to make it work?

other than

asm
INT_LIST macro
      INT_Handler  CCP1_15313_INT,   _myisr,    PBP,  yes
      
      endm
      INT_CREATE


ENDASM

thats about all i recall . http://dt.picbasic.co.uk/ might have some detail i have missed

I have been to http://http://dt.picbasic.co.uk/ a number of times to refresh myself, but I admit, I haven't mined it thoroughly. I went back and found a couple of nuggets. One was in "DT's other code examples" that gave a better explanation of IOC interrupts, the other was by mpgmike named http://dt.picbasic.co.uk/INT16/Customisation.

I had found his explanation on the forums of the PIC18's, but couldn't quite sort it for the lesser PIC's.

i agree, its not very clear which "mods" apply to which dt-ints version
a simple example adding 1 extra or modified dt-int to each version would be clearer
adding a swag of int sources you will never use is an overkill for a pretty simple process

you could use conditional asm constants to add a more generalised approach and standard notation
like this
ifdef PIR6
#define CCP1_INT PIR6,CCP1IF, PIE6,CCP1IE ;-- CCP1
#define CCP2_INT PIR6,CCP2IF, PIE6,CCP2IE ;-- CCP2
else
#define CCP1_INT PIR1,CCP1IF, PIE1,CCP1IE ;-- CCP1
#define CCP2_INT PIR2,CCP2IF, PIE2,CCP2IE ;-- CCP2
endif
but who can be bothered to see if every pic16 chip with a PIR6 has a ccp1 + 2 and conforms to these settings.
and what about new chips
its just not worth the effort these days

[boroko]

With your suggestions I was able to get it working. I will post the basics in case someone else needs to get through this. Having a better understanding of PPS will help a lot moving forward and allow me to take advantage of a lot of new features, some of which I didn't even know existed like an Angular Timer and a Math Accelerator with Proportional-Integral-Derivative (PID). Very interesting blocks to work with.
