Using PIC18F27K40, CCS PCH C Compiler, Version 5.078
I am having problem assigning peripherals using pin select option.
Pin select options from header file below
| Code: |
////////////////////////////////////////////////////////////////// PIN_SELECT
// #pin_select function=pin
// Valid Pins:
// PIN_A0,PIN_A1,PIN_A2,PIN_A3,PIN_A4,PIN_A5,PIN_A6,PIN_A7,PIN_B0,PIN_B1,
// PIN_B2,PIN_B3,PIN_B4,PIN_B5,PIN_B6,PIN_B7,PIN_C0,PIN_C1,PIN_C2,PIN_C3,
// PIN_C4,PIN_C5,PIN_C6,PIN_C7,PIN_E3
// Input Functions:
// INT0,INT1,INT2,T0CK,T1CK,T1G,T3CK,T3G,T5CK,T5G,T2CK,T4CK,T6CK,ADACT,CCP1,
// CCP2,CWGIN,MDCARL,MDCARH,MDSRC,U1RX,U1CK,SCK1IN,SCL1IN,SDI1,SDA1IN,SS1IN,
// U2RX,U2CK,SCK2IN,SCL2IN,SDI2,SDA2IN,SS2IN,T0CKI,T1CKI,T3CKI,T5CKI,T2CKI,
// T4CKI,T6CKI,CCP1IN,CCP2IN,RX1,CK1,U1CKIN,RX2,CK2,U2CKIN
// Output Functions:
// NULL,CWG1OUTA,CWG1OUTB,CWG1OUTC,CWG1OUTD,CCP1OUT,CCP2OUT,PWM3OUT,PWM4OUT,
// U1TX,U1DT,U2TX,U2DT,C1OUT,C2OUT,SCK1OUT,SCL1OUT,SDO1,SDA1OUT,SCK2OUT,
// SCL2OUT,SDO2,SDA2OUT,T0OUT,CLKROUT,DSMOUT,ADGRDA,ADGRDB,PWM3,PWM4,TX1,DT1,
// TX2,DT2,SCK1,SCL1,SDA1,SCK2,SCL2,SDA2,TMR0OUT

Trying to assign 2 external clock counter inputs to these pins.
| Code: |
#PIN_SELECT T3CK=PIN_B1
#PIN_SELECT T1CK=PIN_B2 |
error shown below on compile
*** Error 7 Line 108(12,24): Invalid Pre-Processor directive Invalid Pin: PIN_B2 can not be assigned to T1CK
Also tried #PIN_SELECT T1CK=PIN_B1 THIS DOES NOT WORK
| Code: |
#PIN_SELECT T3CK=PIN_B1 // is fine
#PIN_SELECT T3CK=PIN_B2 // Also Fine |
It will let me assign to other pins on PORTA & PORTC
Can you only assign 1 peripheral to a PORT
| Code: | #PIN_SELECT T1CK=PIN_A5 // Works
#PIN_SELECT T1CK=PIN_C1 // Works |
It appears to be a valid input for pin select option?.
Is this a compiler problem ??
Thanks for all the help.

Thanks for the info.
I should pay more attention to the datasheet. Bummer.
Thanks again. |

Yes, it's annoying isn't it....
It's a bit of the 'evolution' of PPS. The latest chips allow things to route
to any pin, while the older PPS chips have restrictions like this.  |

At least you don't have to wait 15 minutes waiting for the UV eraser to make your PIC 'just like new' again, an again , and again........  |

I remember those days.
I have some of those PICs sitting up behind me.
LoL.... those were the days.

Yes, and it was the fact that it took so long, that even if you had perhaps
six chips in use, and four chips in the eraser, you still found you had run out
and had to wait...
The launch of electrically erasable chips was a 'magic' day.  |
