Hi,
can anyone get me 7 segement LED circuit for PIC16f877.
Thanks

hi,
You have to specify Common anode or Common cathode LED types and how many LEDs.

Hi,
I have both ...so no problem if i get one of the circuits.I wish to use 2 LEDS to display 2 digit BCD number.

Thanks Gibbs !

hi,

Have a look at this forum link
http://www.electro-tech-online.com/e...gment-led.html

Its for a 16F268A, but the LED wiring will be the same, you could modify the asm code to 'C'

EDIT: the 14th Sept posts. Mike K8LH and mine.

if u r output is BCD so u need decoder IC

one option is 7447 of Common anode or 7448 Common cathode LED c this IC datasheet for connection this TTL also u have CMOS but i dont remember the type now

As always, this is covered in my tutorials, and like Eric says in a fairly recent thread - do you ever look for yourself before you ask questions?.
