First I think, how to build a USBasp programmer.But I have n't a usb programmer to flash the firmware to it. Then decided to create a serial programmer and flash the firmware through this programmer to atmega8. My AVR serial programmer will transform hex file to most AVR microcontroller. It can build using few readily available components. This programmer is compatible with popular avrdude software or PonyProg software.We will be using the serial port for burning. First, we have to develop a burning circuit for it.
