    Capacitance meter using 555 timer

    nicholas.frank

      I am attempting to complete a PSoC1 project involving using a 555timer circuit as a capacitance meter. Essentially the resistor/capacitor network in the circuit directly relates to the 555timer output in that t = 1.1RC. I am fine with the circuit design, my problem is in writing the main.c file for it. I need to be able to read in the 555 output, have PSoC recognize the T value, and calculate for capacitance and display it to the LCD. Any help would be greatly appreciated.
