Hi Marko, You don't need interrupts for designing a clock, however can be done with interrupts either. Take a look to this one (it's in jalv04 with assembler, but you will probably understand the ideea how the multiplexing scheme works): http://webspace.webring.com/people/dv/vsurducan/electro/PIC/newclk.txt The answer to your question is probably the procedure named "display"
