Summary of PIC16C622 MICROCONTROLLER MEASURING THE RESISTANCE CAPACITOR RC METER CIRCUIT
This article describes the PICMETER, a circuit based on the PIC16C622 microcontroller that measures resistance (1Ω to 999Ω) and capacitance (1nF to 999nF). It utilizes an exponential charge waveform comparison method instead of traditional integrating converters. The system connects to a PC via assembly language software prepared in Visual Basic to display measured values.

RESISTANCE, CAPACITOR METER CIRCUIT SCHEMATIC
The application circuit, called PICMETER, uses a PIC16C622 as a resistance and capacitance meter. The PICMETER uses a variation of the single-slope integrating converter. The linear slope and integrator of Figure 13 are replaced with the exponential charge waveform of an RC. The charge time of a known component is compared against the charge time of an unknown component to determine the value of the unknown component.
A schematic of the PICMETER is shown in Figure 16. All reference designators cited in this section refer to this schematic. Results are transmitted to a PC which displays the value measured.
