PIC16F18855 and DT elapsed timer
Hello to you all,
As PIC16F876A become obsolete I decided to use PIC16F18855 to replace it, it is much cheaper than the old PIC16F876A and has more features.
I implemented the code below (using PBP3) to get sure that the faithfull ELAPSED TIMER from Darrol's would still work with the new PIC
''* Name : test_pic16f18885.PBP *

if SecondsChanged = 1 then
SecondsChanged = 0
Toggle StatLED ' counting seconds is "alive"
endif
led=1
pause 100
goto main
However the compilation always return:
[ASM ERROR] Symbol not previously defined (INT_ENTRY) (0) : ERROR[113)
[ASM ERROR] Symbol not previously defined (INT_ENTRY) (0) : ERROR[113)
[MESSAGE] pic16lf18855.pbpinc(603): HPWM command only supports CCP channels (not PWM channels).
Can any of you tell me how to solve this?
Thank's in advance

Re: PIC16F18855 and DT elapsed timer
Several versions of ELAPSED_INT seems to exist. One that predates the existance of DT-Ints and one which is supposed to work WITH DT-Ints. For the one that's using DT-Ints it looks like you also need to include ReEnterPBP.bas file. Here's an example by Darrel himself, from this thread:
Code:
INCLUDE "DT_INTS-14.bas"
INCLUDE "ReEnterPBP.bas"
INCLUDE "Elapsed_INT.bas" ; Elapsed Timer Routines
ASM
INT_LIST macro ; IntSource, Label, Type, ResetFlag?
INT_Handler TMR1_INT, _ClockCount, PBP, yes
endm
INT_CREATE ; Creates the interrupt processor
INT_ENABLE TMR1_INT ; Enable Timer 1 Interrupts
ENDASM
GOSUB ResetTime ' Reset Time to 0d-00:00:00.00
GOSUB StartTimer ' Start the Elapsed Timer
Main:
IF SecondsChanged = 1 THEN
SecondsChanged = 0
LCDOUT $FE,2, DEC Days,"d-",DEC2 Hours,":",DEC2 Minutes,":",DEC2 Seconds
ENDIF
GOTO Main
Also, OSCFRQ = %11 can't be right but I suspect that it's the forum messing with the text.
When posting code, please use the proper code tags.

Henrik posted the same code 1 second before me. So I deleted mine. :)
