Discussion: Very Accurate LC Meter based on PIC16F84A IC
Quote:
This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself. This LC Meter allows to measure incredibly small inductances starting from 10 nH to 1000 nH, 1 uH to 1000 uH, 1 mH to 100 mH and capacitance from 0.1 pF up to 900 nF.
Here are 3 text files in the archives. That is .hex files. You need to change .txt extension to .hex (Intel hex format). Files #2 and #3 - with the self-calibration function.
