Operation of 7 segment LED display with avr studio4 without using max7221 driver ic

[shom_show]

Myself Sumanta Kumar Show is trying to operate a 7 segment LED with avr studio4 using

Atmega32. What I have seen in internet that normally MAX7221/7219 driver IC is required. I

am trying to do that same thing without using MAX7221. Can anyone please give me his

suggestions or any sample program if you have for operating the 7 segment LED with avr

studio4 but without using max7221 ic. Yours suggestions will be highly appreciated. If possible

please email me on the below Email IDs.

Thanks in advance.

If I understood it correctly you want to interface seven segment LEDs to an AVR without using any MAXIM driver. Try these:
