Based on Franck-Hertz experimental instrument and photoelectric effect experimental instrument, an universal experimental interface is proposed. And its circuit is designed, which is based on an ARM Cortex-M3 core 32 bit processor STM32F103. The interface is a data exchange center between the experimental instrument and visual display. It can collect the analog data from experimental instrument, after A/D conversion and storage, then the result is sent to the host computer or the oscilloscope after D/A conversion. Besides, it can also export digital signal to control the analog output of experimental instrument, collect the analog data and export digital signal to the oscilloscope after the interface’s processing. Furthermore, the universal interface has the interface which can be upgraded by on-line, and can be updated by the remote software.
