Title: can i use this serial port or not for ATmega8?!!
Post by: mohamed on March 16, 2008, 11:03:26 AM

now the final step is programming the ATmega8 in the 50$robot
but the admin said in the tutorial that u r goging to need either the AVR STK Serial Port Dongle Programmer
or the AVR ISP2 Programmer
but the first one i didnt find it and the other is too expensive for me so can i use just a normal serial port and i connect it to the board by a serial port socket instead of the 10 pin header but it will be 9 pins instead of 10 so i dont know if this is possible
here is a pic for what i mean (seial port socket and serial port)

first you'd need to instal a bootloader into the atmega8. then you can program it without the dongle. but until then you'll need to find a programmer

On instructables.com there are step for creating your own AVR programmer.

Ahh here is the link

thanks pomprocker thats realy good link and easy for a noob to follow  ;D

i mean that i can ollow the tutorial steps (50$ robot) as it is or there will be any changes
thanks

If you build a separate programmer, you don't need to incorporate it into your $50 robot board (no male headers in the corner, and no blue wires underneath).


ponyprog will send out to any com port you set it to.
