This paper introduces one design method of embedded digital oscilloscope based on STM32 and μC/OS-II. The hardware adopts STM32 and the custom data buffer to realize the 2 channel data synchronizations. The software uses the μC/OS-II platform to realize the multi-duty movement and the real-time processing. The test indicates that this embedded digital oscilloscope supports 2 channel inputs and the sampling frequency scope is 25Hz to 10MHz. Its input voltage is -3.6 V to +3.6 V and it has good man-machine interaction contact surface.
