the XTAL1 is connected to ground instead of GND
SCK is connected to VCC instead of RESET

I put it one pin down.. you get it.

i didn't suspect there is a problem, but when i want to reprogram it , i was surprised:
uisp -dprog=dapa -dlpt=/dev/parport0
Atmel AVR ATmega163 is found.

can i just use it, or??
any advice??]]> Thu, 14 Feb 2008 04:15:05 -0800 http://www.8051projects.net/forum-t5846.html http://www.8051projects.net/forum-t5846.html try to program it. maybe its possible to use it. just toggle all ports and check on CRO if all pins are working then its fine...

I still have no idea.. why its showing ATMega163 ]]> contact@nospam.com (Ajay Bhargav) Thu, 14 Feb 2008 07:48:29 -0800 http://www.8051projects.net/forum-t5846.html http://www.8051projects.net/forum-t5846.html it wasn't showing atmega163 really. it was showing different signatures each time.

i tried programing it
Reading############################################# | 100% 0.00s

avrdude: Device signature = 0xffffff
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

when i use -F : it programs the chip , but my MM didn't get anything.

i just start to loose my patient with it..]]> contact@nospam.com (Ajay Bhargav) Tue, 19 Feb 2008 23:45:10 -0800 http://www.8051projects.net/forum-t5846.html http://www.8051projects.net/forum-t5846.html sorry...

may god give you strength to bear this pain ]]> contact@nospam.com (Ajay Bhargav) Wed, 20 Feb 2008 04:53:37 -0800 http://www.8051projects.net/forum-t5846.html http://www.8051projects.net/forum-t5846.html

it happens with everyone , thank god we are fine.
now i am playing with my mega32 , but i must be carefull - it the one and only now -

the proplem is that i am using a cheap programmer and my breadboard so the chip is grasped from here and put over there all the time.

and a test board in the same time so that i can test my serial, ADC, LCD, etc
stuff with it.

can i make it in a simple breadboard , i do not like smell of soldering.

thanks.]]> contact@nospam.com (Ajay Bhargav) Thu, 28 Feb 2008 00:10:42 -0800 http://www.8051projects.net/forum-t5846.html http://www.8051projects.net/forum-t5846.html soldering is good..
start your schematic.. will help you as you go forward..]]> contact@nospam.com (Ajay Bhargav) Fri, 29 Feb 2008 03:46:37 -0800 http://www.8051projects.net/forum-t5846.html
