Microcontroller working state obtaining method, device and system and readable storage medium

Abstract

The invention discloses a microcontroller working state obtaining method, device and system and a readable storage medium. The obtaining method comprises the steps: acquiring the current and voltage of a microcontroller and a first timestamp set corresponding to the obtained current and voltage; searching a sleep wake-up event output by the microcontroller, a second timestamp corresponding to thesleep wake-up event, a program running event output by the microcontroller and a third timestamp corresponding to the program running event from the first timestamp set; calculating average transientpower consumption of the microcontroller according to the current and the voltage of the microcontroller, and drawing an average transient power consumption curve of the microcontroller; calculating average transient power consumption corresponding to each event according to the second timestamp, the third timestamp and the current and voltage of the microcontroller; and identifying a sleep wake-up event and a program running event on the average transient power consumption curve. According to the scheme, a tester can accurately know the specific working state of the MCU in real time.
