Hi all, I need some help for finding a way to counting a circuit’s value, and I need them fast, because I have to finish it for the day after tomorrow. :cry:

Please include explanations and your step by step.

Can someone help, please view the page here:


there are some mistakes on the schematic, which is the Vss should be Grounded and Vdd should be on +5.

I need to know how to count the limiter (is it right?) for the 7-seg
I need to know how to count the pull-ups(what is it?) for the DIP switch
I need to know how to count the R and C for the PIC’s oscillator
What else should be counted?

Thank You

PS: I’ve posted a message for how knowing does the software works too, because I have to draw a flowchart for the circuit and show how it works. Can someone please help me with this? I’m really time short and I’ve read the PIC’s datasheet for 3 days and still cant understand the software, I didn’t even know what EQU is for….

Thank you very very much

What do you mean when you say "count"?
Are you looking to find the frequency?
Are you looking to find the voltage and amperage?
