the 16F684 does

[/QUOTE]Hello manjero, I think that Darrel missed the fact that you're using an 'F84. You can drop the:-

CMCON0 = 7
ANSEL = 0

The 'F84 doesn't have any analogue inputs to turn off or configure as digital IO. They're always digital IO. In fact, I have 16F84(A) selected, the compiler, (v 2.44), doesn't even recognise CMCON0.

I built the circuit using 4 74hc595 cascaded and with a pic16f684 i had laying around with a 4 MHZ xtal.
