Electronic – Programming Atmega with serial port

atmegaprogrammer

Hey people, I need to program the ATmega8 chips via serial. I understand that for doing that I would need to install a bootloader on the chip. And to install a bootloader, I would need a parallel port programmer. Am I right? Or can I just hookup the chip with an MAX232 to make a programmer? I am really confused right now. The best answer here would be a circuit.

UPDATE

He people I just found this http://www.qubbeks.puslapiai.lt/images/articles/AVR_programmer/avr_programatorius_schema.jpg. Do you think this is the kind of circuit which won't require any bootloading?

Best Answer

No need for bootloader.

Then use uniprof program to flash your AVR. I personally used that.
