Hello

There is no need for the support of SEVEN SEGMENT DISPLAYS any way, as they always need some kind of multiplexing/refreshing issues that causes annoyance to the PIC programmer, the simplesy way is to use TMR0 overflow, which will then have to be polled, or used in interrupt.

So why bother your self my friend, if I want to use four seven segment displays then this will cost me 9$, while when I go for an LCD I will pay 14$, also think about it as more cost effective option, as you can view text also

Have a nice day
