Problems solved by technology

[0004] However, when the TV enters the working state of standby, restart, shutdown, etc., the serial port will not work normally, that is, the CPU and MCU cannot communicate through the serial port, so that the MCU cannot accurately obtain the working state of the TV from the CPU and perform corresponding operations. , therefore, the accuracy rate of CPU to MCU control is low

Embodiment 1

[0044] An embodiment of the present invention provides a method for the MCU to obtain the working state of the TV, such as figure 1 As shown, the method may include:

[0045] S101. If the MCU detects a first interrupt, the MCU counts it once. The first interrupt is triggered by the CPU and sent to the MCU when the TV enters the first working state from the normal working state.

[0046] MCU, also known as SCM (Single Chip Microcomputer, single-chip microcomputer) or single-chip microcomputer, refers to the computer's CPU, RAM (Random Access Memory, random access memory), ROM (Read- Only Memory, read-only memory), timer counter and various I / O (Input / Output, input / output) interfaces are integrated on a chip to form a chip-level computer, which can be used for different combination control for different applications.

[0047] The CPU is a very large-scale integrated circuit, which is the computing core and control core of a computer. It mainly includes two parts: arithmetic un...

Embodiment 2

[0081] Such as Figure 5 As shown, the embodiment of the present invention provides an MCU1, and the MCU1 may include:

[0082] The detection unit 10 is used to detect a first interrupt and a second interrupt, the first interrupt is triggered by the CPU and sent to the MCU when the TV enters the first working state from the normal working state, and the second interrupt is the The CPU triggers and sends the first interrupt to the MCU after n times, where n is the number of interrupts corresponding to the first working state, and n≥1.

[0083] The counting unit 11 is configured to count once if the detecting unit 10 detects the first interruption once.

[0084] The statistics unit 12 is configured to count the number of times of the first interruption recorded by the counting unit 11 when the detection unit 10 detects the second interruption.

[0085]The obtaining unit 13 is configured to obtain the first working state corresponding to the number of first interruptions accord...

Embodiment 3

[0092] Such as Figure 7 As shown, the embodiment of the present invention provides a TV 2, the TV 2 may be a smart TV, the TV 2 may include the MCU1 described in Embodiment 2, and a CPU3 controlling the MCU1, wherein,

[0093] The CPU3 is configured to trigger a first interrupt when the TV 2 enters a first working state from a normal working state, and send the first interrupt to the MCU1, and when the first interrupt is triggered n times Afterwards, a second interrupt is triggered and sent to the MCU1, where n is the number of interrupts corresponding to the first working state, and n≧1.

[0094] Further, the CPU3 is specifically configured to trigger the first interrupt by setting the value of the first GPIO pin, and trigger the second interrupt by setting the value of the second GPIO pin.

[0095] An embodiment of the present invention provides a TV, the TV includes an MCU and a CPU controlling the MCU, wherein, when the TV enters the first working state from the normal w...

Abstract

The embodiment of the invention provides a method and device for acquiring a television working condition through an MCU, and relates to the technical field of electronics. The method comprises the steps that if the MCU detects a first interruption once, the MCU counts once, and a CPU triggers and sends the first interruption to the MCU when a television enters the first working condition from a normal working condition; when the MCU detects a second interruption, the MCU carries out statistics on the number of times of the first interruption, the second interruption is triggered and sent to the MCU after the first interruption is triggered by the CPU n times, wherein n is the number of times of the interruption corresponding to the first working condition, and n>=1; the MCU acquires the first working condition corresponding to the number of times of the first interruption according to the number of times of the first interruption, and the accuracy of control over the MCU through the CPU can be improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and a device for an MCU to obtain the working state of a television. Background technique [0002] With the continuous development of electronic technology, electronic products are changing with each passing day, especially television has become an indispensable electronic product in people's life. [0003] In the prior art, when the TV is in a normal working state after being turned on, the CPU (Central Processing Unit, central processing unit) of the TV can communicate with the MCU (Micro Control Unit, micro control unit) through a serial port, that is, the CPU can communicate through The serial port controls the MCU to perform corresponding operations. For example, the CPU can send the normal working status of the TV to the MCU through the serial port. After the MCU obtains the normal working status of the TV, it can perform corresponding operations according to ...
