Is it necessary to use MAX 232 IC for AVR Microcontroller programming.????
Because i have seen many programmer circuits that on programming with RS 232 protocol uses MAX 232 and there are also many that without using any intermediate IC, programs the circuit simply by connecting some resistors and transistors in between the serial port and the MCU.
