Abstract

STM32 is highly integrated, easy to develop, and has a wide range of communication interfaces. In this paper, two STM32F103-based LVDT signal conditioning programs are designed, the hardware circuit is simulated, and an experimental platform is built. The simulation and experimental results show that the conditioning circuit is stable and reliable. The interrupt program of SPWM technology will occupy CPU resources, reduce the frequency of the excitation source, and make the circuit more complex. The DAC_DMA technology circuit structure is simple and reliable, which reduces the burden on the CPU, and the excitation signal frequency is stable at 10Khz.
