The story of LCR-T7 firmware development and its community starts with its initial release. The LCR-T7 was designed to be an affordable and versatile tool for measuring inductance (L), capacitance (C), and resistance (R), hence the name LCR. It can also measure other parameters like ESR (Equivalent Series Resistance) and sometimes comes with additional functionalities.
You selected the wrong MCU. Try -p m324p or -p m644p . Also check your wiring – loose GND is a common culprit.
