Instant Interrupts - Revisited

[Darrel Taylor]

Since everything was working fine I commented out the error routine for T4.

As long as the long formula isn't in the Interrupt Handler, you should be OK.

There's no way for the program to tell if a complex formula is in the handler or somewhere else. So I err'd on the side of caution and had it give a warning no matter where it is.

Glad you like it.

Maybe on POST 116 which is few time after the Green splat thingy

Good day to all!!!
I'm Ryan from the philippines i've been wanting to use my homebuilt icd2 but i'm having a hard time compiling my sourcecode with Darrel's instant interrupt in MPLAB has anyone tried and successfully compiled it in MPLAB?
To anyoneThanks in advance!!!

[mister_e]

is this happen to ANY PBP program or just when using DT-INT.

I don't know why it shouldn't. can you at least post some code OR the errors message + PIC#

[leisryan]

Yes indeed just when using dt_ints it fails to compile here are the following error message

"Executing: "C:\PBP\PBPW.EXE" -p16F877A -ampasm -oq -z "SMS_CONTROL1_MPLAB.bas"

Which version of PBP?

[mister_e]

The problem is due to your LCD DEFINES

    		' 	LCD Display
    		'	-----------
    	DEFINE LCD4X20 	
    	DEFINE LCD_DREG	       	PortD		' Set LCD Data to PortD
    	DEFINE LCD_DBIT	       	0		    ' Set starting Data to Bit0
      	DEFINE LCD_EREG	       	PortD		' Set LCD Enable to PortC
    	DEFINE LCD_EBIT        	5		    ' Set LCD Enable line to PortC.1
    	DEFINE LCD_RSREG       	PortD		' Set LCD Register Select to PortB
    	DEFINE LCD_RSBIT       	4		    ' Set LCD RS line to PORTC.0
    	DEFINE LCD_BITS	       	4		    ' Set for a 8 bit Bus

Always make sure that ALL DEFINEs are properly written. you MUST use PORTD in uppercase.
