Hi everyone ......
I am dealing with pic16f84 using comparators to measure high and low limits......
to test large numbers of 1000-ohm resistors to an accuracy of ±5%..
to measure resistance is to use a constant current generator to force a known current through the resistor and hence measure the voltage across the resistor to obtain the current value.........
the 16F84 based design will need to use external circuits to compare the voltage across the resistor to pre-determined high and low limit values, then present the result to the PIC as digital inputs. Assume resistors to be test are in the range 1Kohm to 4700ohms.
I need source code to run this mc pls help me........
Can anybody help me please?
