K kaizer002 New Member Mar 12, 2010 #1 I'm making a project and I choose multiplexing 4 seven segment displays with my PIC16F877a. Here's how it goes: the first two seven segments will display the "Minutes" and the last two seven segments will display "Seconds". **broken link removed** Please help me with the source code since I'm having difficulty with that. Thanks in advance..!
