S shom_show New Member Jul 15, 2012 #1 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. Email Id - (sumanta.show@gmail.com / show.sumanta@rediffmail.com)

R rajbex Member Jul 17, 2012 #2 If I understood it correctly you want to interface seven segment LEDs to an AVR without using any MAXIM driver. Try these: http://extremeelectronics.co.in/avr-tutorials/multiplexed-seven-segment-displays-part-ii/ **broken link removed**
