Portable LCR meter on PIC microcontroller
LCR meters are included in professional measuring instruments are quite expensive to purchase. So if you need one and don’t want to spend too much money on that - the only way is to build one.
This LCR meter is based on dsPIC30F4012 microcontroller. Device can be used to analyze the analog performance of any analog device. LCR meter combines various techniques like DDS signal generation, DSP algorithms to evaluate analog signal properties. Information is displayed on graphical LCD. Project files can be downloaded here.
