AVR-Chat

Inthe following code, I am getting a fata "Invalid Number" error on the 
line with the out instruction. I have tried this with bot h the register 
name as defined in the def file (TCNT0) as well as with the literal 
register address (0x2f), which is the value defined in 1n15def.inc 
file.  Why is it telling me "invalid number?  (note, I have also tried 
moving the value from r31 ro r0 and outputting it from there.  same 
error)    I am flummoxed.


;  begin

.include "tn15def.inc"

; set interrupt vectors, if any
;
reset:
   rjmp start
   reti      ; Addr $01
   reti      ; Addr $02
   reti      ; Addr $03
   reti      ; Addr $04
   reti      ; Addr $05
   reti      ; Addr $06        Use 'rjmp myVector'
   reti      ; Addr $07        to define a interrupt vector
   reti      ; Addr $08
   reti      ; Addr $09
   reti      ; Addr $0A
   reti      ; Addr $0B        This is just an example
   reti      ; Addr $0C        Not all MCUs have the same
   reti      ; Addr $0D        number of interrupt vectors
   reti      ; Addr $0E
   reti      ; Addr $0F
   reti      ; Addr $10

You have them back to front :)

Try     out  0x2f,r31                   ; store in timer/counter 1

Better use the actual register name (TCNT1 ??) rather than the
address as it may change in another chip so that you will be able
to reuse your code.

Thanks, John.  I figured that out about 3 minutes before your reply 
arrived in my inbox *blush*.

   Yeah, I was using the label, but switched tot he literal in a failed 
attempt to eliminate the error.
