DT Instant Interrupts - Clarification?

[HenrikOlsson]

That is correct, there are two versions - one (DT_INTS-18) for PIC18 and one (DT_INTS-14) for PIC12 and 16. See here for more details.

Hmmm.... it would appear that DT_INST-14 doesn't work with PIC12F683
I downloaded Ver 1.1 of the application and trialed the "Hello World" program from Darrel's website.
I made the necessary change from PORTB.1 to GPIO.1 for the LED1 variable but got a host of errors when compiling:

Error[101] DT_INTS-14 TEST.ASM 235 : ERROR: (wsave variable not found,)
Error[101] DT_INTS-14 TEST.ASM 201 : ERROR: (" Add:" wsave VAR BYTE $20 SYSTEM)
Error[101] DT_INTS-14 TEST.ASM 256 : ERROR: (Chip has RAM in BANK1, but wsave1 was not found.)
Error[101] DT_INTS-14 TEST.ASM 208 : ERROR: (" Add:" wsave1 VAR BYTE $A0 SYSTEM)


Should I be able to do this with a PIC12F683?
Can anyone provide some input to this problem?

I have attached a copy of the full code for review.

Cheers

The cool thing is the answer is in the error message.

Error[101] DT_INTS-14 TEST.ASM 235 : ERROR: (wsave variable not found,)
Error[101] DT_INTS-14 TEST.ASM 201 : ERROR: (" Add:" wsave VAR BYTE $20 SYSTEM)

So..
Put
wsave VAR BYTE $20 SYSTEM
in your code's variable section.

Thanks Dave.

I have added the two variables wsave and wsave1 as specified in DT_INST-14.bas
I now have more errors at compilation:

Any clues here?

Again, I have attached a copy of my main code for review.

It's trying to compile both your source file and the include file separately.
Remove DT_INTS-14.bas from the "Source Files".

You should only have your main program in the source files list of MPLAB.

[Aussie Barry]

Thanks Darrel - that did the trick.

Now that I have the simple things sorted it is onwards and upwards to bigger and better phases of my project.

OK, I have now tried to implement the DT_INST-14 routines into my main project code. The attached code file has sufficient comments to explain what it is doing.

I am getting the following errors when I try to compile the program:

Executing: "C:\PBP\PBPMPLAB.BAT" -ampasmwin -k- -p12F683 "PICSprayer.bas"
Executing: "C:\PBP\PBPW.EXE" -ampasmwin -k- -p12F683 "PICSprayer.bas"

Halting build on first failure as requested.
BUILD FAILED: Fri Jul 08 11:35:51 2011

My code compiles properly without the interrupt routine for the manual switch operation. Now I just don't know where to start looking to fix these errors.

Any help would be greatly appreciated.
