First, once I make changes to a file in studio 4 I save it and then
build it. After building do I have to save it again before
programming or exiting?

Right now all leds are on except one that runs across. I want all
off and one on to run across. I have tried everything I know with no
good results. The leds on the STK500 are connected to Vcc. I dont
get any errors or warnings on building. It works on debug but not on
my mega16. I've tried to invert all the bits thinking that may do it
but no change.

Timer:
(This is my delay timer so I can see it work)

; set time has passed, rotates LEDs

mov Counter, Speed ; resets counter
in temp, PortB ; reads in current state
rol temp ; rotates to the left
out PortB, temp ; outputs to PortB

brcs PC+2 ; checks Carry Flag, skip if
set
ldi temp, 0b11111110 ; resets to PB0 on, others
off

rjmp Start ;loops back to Start

Thanks,
Brian

Whoo Hoo, I figured it out. I had to set the carry flag before I
rotated my leds and I also forgot to sent temp to PortB. Duh! This
also required a PC+3 for my branch.
