Hi, I've completed a circuit for an ATmega88 that is to be programmed through Serial Port. I've tested it with LED and now I want to hook up a triple 7 segment display (common cathode) to give it a 10 minute counter. 000 to 959 (before resetting).
So my question is, now that I have purchased a 7 segment CC, how do I do the circuitry to attach it to the AVR properly. From what I have seen, a single 7 segment display has 10 inputs (2x GND, A->G, dp). My triple 7 segment displays has 11 pins on it. And from looking at the ATmega88 specs sheets, it has 6 PORTB, 6 PORTC, 8 PORTD which I can use for programming. Although PORTB0 is for input capture for timer/counter (what does this mean?).

Hopefully a lot of the capabilities from the delay program will work for this one. Thanks Maybe I should add the 7 Segment CC P/N is LEDSM-314220 (although an online search turned up nothing). It says RGE30361LP on the side as well. On the back 6 pins at top and 5 points at bottom. -- View this message in context: http://www.nabble.com/ATmega88-%2B-triple-7-Segment-Display-%28CC%29-tp15708386p15708386.html Sent from the AVR - General mailing list archive at Nabble.com. _______________________________________________ AVR-chat mailing list AVR-chat@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-chat
