Embodiment Construction

[0021] In practical applications, when using the online debugging technology to debug the application system of the MCU, testers cannot know the specific working status of the MCU in real time.

[0022] In the embodiment of the present invention, the current and voltage of the microcontroller and its corresponding first time stamp set are obtained, and the sleep wake-up event output by the microcontroller and its corresponding second time stamp, Program running events output by the microcontroller and their corresponding third time stamps. Plot the average transient power consumption of the microcontroller against the current and voltage of the microcontroller, and calculate the average transient power consumption for each event. On the average transient power consumption curve, marking each dormancy wake-up event and each program running event can enable testers to know the specific working state of the microcontroller in real time and intuitively.

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.

Description

technical field [0001] The invention relates to the technical field of microcontrollers, in particular to a method, device, system, and readable storage medium for acquiring the working state of a microcontroller. Background technique [0002] With the development of the Internet of Things (Internet of Things, IoT) technology, a variety of IoT products are derived, and the IoT products have higher and higher power consumption requirements for a microcontroller (Microcontroller Unit, MCU). Therefore, it is necessary to debug the MCU to measure the specific power consumption of the MCU. [0003] In the prior art, the online debugging technology is usually used to debug the application system of the MCU online. However, when using online debugging technology to debug the application system of the MCU, testers cannot accurately know the current specific working status of the MCU in real time, including sleep mode, power consumption, etc. Contents of the invention [0004] Th...
