I am new in embedded System. I want to use PIC16F1827 to indicate the voltage level of my self made high voltage DC variable Power supply.

I have done all I could to make this work well but it turns the LED on for example >= 0.47 and could not wait until it gets to <= 0.40 before it turns the LED off. It suppose to wait until it decreases to <= 0.40 before it turns off.

Attached are the source file and the Proteus simulation circuit .

Thanks.
Michael.

 

The Code is written in CCS C

 

This line (and similar for the other outputs) is the problem:
else output_low(PIN_B0);
Just delete these lines.

 

@AlbertHall, You are just a CCS C master!

It works right now but there is this error I get, it counts up to 10,000! Though is does not stop the circuit from running well but to me an error is an error! Is there anything that I write or selected wrongly that can cause this error? The snapshot of the error is attached

 

In init() you need to add lines like this:
ANSELA = 0x0F; // Set A3:A0 as analogue
TRISA = 0x0F; // Set A3:A0 as inputs
TRISB = 0; // Set port B as output

Note that I don't use CCS and it may use different register names.

OK I'll try it Sir.
