Help with code

Ok

so ...

reading PORTD ...

		
B=PortB : C=PortC.5

D = PORTD & %11111100 ' read PORTD and mask port D.0 and D.1

IF B=0 and C=0 and D=0 then
		toggle BUZ: pause 20
	endif

should fit ... no indexing necessary !

( BTW ... not sure it was working so fine ... lol )

Thanks a lot. Problem solved.

This time the problem is with 16F676. While compiling I get the following errors

ERROR: Unable to fit variable RM2_Save
ERROR: Unable to fit variable RR1_Save
ERROR: Unable to fit variable RR2_Save
ERROR: Unable to fit variable RS1_Save
ERROR: Unable to fit variable RS2_Save

I am using DT-Interrupts in this code. Can some1 help me to get rid of these problems and what can I comment out in the ReEnterPBP or the other DT_INTS-14. Thanks

The only thing I am doing in the ISR is the following:

ToggleLEDF:
     If F1=1 then Toggle PortA.0
     If F2=1 then Toggle PortA.1
     If F3=1 then Toggle PortA.2
@ INT_RETURN

'---[TMR2 - interrupt handler]--------------------------------------------------
ToggleLEDS:
     If S1=1 then Toggle PortA.0
     If S2=1 then Toggle PortA.1
     If S3=1 then Toggle PortA.2
	pause 100
@ INT_RETURN

Sure 64 Bytes of SRAM is a bit weak to handle DT-Interrupts ....

Try to spare (re-use ) 5 of your byte variables ... may be you can re-use B,C,D and two other temporary variables elsewhere in your Program ...

@ first C can be declared as a BIT ... probably others too ...


Or change for a Wider RAM Chip

Or Ask Darrel for a "Fast Interrupt" Option saving only the " live " registers and letting you choose which variables really need to be saved ... such C " #pragma disablecontexsaving " directive ( I'd love such an option !!! )
