please help regarding ATMEGA162 and STK500 - kkazakos2003 - Mar 3 11:45:00 2006

Hello dear friends,

I am currently new in th euse of STK500 for ISP programming.
I am using an ATMEGA162.

The little thing that I am trying to do is to light a led in the STK500.

My code is like this:
--------------------------------------------------
.include "m162def.inc"

.org 0x000
rjmp RESET	;external pin, power-on and watchdog reset

.def temp1  = r16
.def temp2  = r17 

;--Main source code

RESET:
	ldi temp2,0xff	
out DDRB,temp2	ldi temp1,0x01
out PORTB,temp1	

-----------------------------------------------

I know it is quite simple, but i want to begin from the simple things
first..

The problem that I have is that it simply does not work in the STK500.
I mean, when I used an ATMEGA161 it worked perfectly.

Right now with th euse of the ATMEGA162 it does NOT work.
ANd i cannot understand why..

Please help me..

thanks

Re: [AVR club] please help regarding ATMEGA162 and STK500 - Jim Bacon - Mar 4 11:02:00 2006

the STK500 hardware "inverts" the logic output of the ports to the 
LED's on the board, such that:
a "0" lights the LED,
a "1" turns it off.

if that's all there is to your code, LED 0 should be OFF, and LED's 
1-7 should be ON.

... that assumes you put jumpers from the port B pin header to the 
LED header ...

Re: [AVR club] please help regarding ATMEGA162 and STK500 - kkazakos2003 - Mar 7 12:16:00 2006

Hello and thanks for the reply.
I apologise but maybe I have not expressed my problem correctly.

The problem that I face with the STK 500 and the ATMEGA162 is the 
following:

I download a simple code (i want to "light" led 0 out of port b) in 
the ATMEGA 162 using the STK 500. I am waiting to see in the board ( 
after I have connected the led headers with the portb ones) the led 
0 off and all the other leds on. This is NOT working. I see all the 
leds off.SOmething which is not logical. 

If I use an ATMEGA161 it is working perfectly.

What might be going wrong?

thank you
kostas
