Sorry if this is a silly question but i am struggling to think straight.
I have a 7 seg display common anode, with the +Vcc connected to a boosted 5V supply. The avr is running at 3V, this is giving me a problem that the LED's are slightly illuminated when they should be off(due to the potential difference). To turn the LED's on i just turn the AVR output low then back on to turn LED's off.
What would be the best way to run the 7 segment with this configuration, so i get the LEDs off when they should be.
