Configure the STM32 to use dual ADC mode. ADC1 measures the voltage channel, and ADC2 measures the current channel. They should be triggered simultaneously. DMA should be configured to store a buffer of samples (e.g., 1024 samples per channel).
—to characterize components accurately across their operating range. Design & Build Quality Advanced Analog Front-End (AFE) Create A Low-Cost- High-Accuracy LCR Meter With An STM32 MCU
You have two primary options for generating the sine wave excitation: Configure the STM32 to use dual ADC mode
Extensive protection is necessary, often utilizing series resistors and low-leakage diode clamps to prevent the device under test (DUT) from exceeding the supply voltage and damaging the op-amps. Create A Low-Cost- High-Accuracy LCR Meter With An STM32 MCU
