hi, I have a atmega8 ic and I have planned to build a serial interfacing circuit for it with max232 ic and rs232 cable. the thing that I want to know is, what is software that I can use to transfer my programme(hex file) from computer to the microcontroller using rs232 and max232 interfacing.
If you want to programe (transferring hex file to micro) you need a boot loader to accept the data and write it to the flash of the micro. So you need a programmer to write the bootloader first.
