Problems solved by technology

Later, even if the HDMI cable of the display device is plugged into the HDMI of the computer again, because the CPU will no longer initialize the HDMI conversion chip (that is, the HDMI conversion chip will no longer be configured), the HDMI conversion chip will not work, and the display device will not be able to receive Computer HDMI signal
In other words, the computer does not have HDMI hot plug function

Abstract

The invention provides an HDMI conversion chip initialization method and device and a storage medium. The method is applied to a processor, the processor is connected with a first pin of a high-definition multimedia interface (HDMI) through a first interface, and the method comprises the following steps: reading an interrupt state of the first interface, the interrupt state of the first interfacebeing used for indicating a state of the first pin, and the state of the first pin being used for representing a plugging state of the HDMI; and if the state of the first pin represents that the plugging state of the HDMI is a plugging state, calling an interrupt processing function corresponding to the first interface to initialize an HDMI conversion chip. According to the HDMI conversion chip initialization method and apparatus, and the storage medium provided by the invention, the HDMI hot plug function of the electronic device can be realized.

Description

technical field [0001] The invention relates to computer technology, in particular to an HDMI conversion chip initialization method, device and storage medium. Background technique [0002] The computer is provided with a central processing unit (Central Processing Unit, CPU for short), a High Definition Multimedia Interface (HDMI for short) conversion chip, and HDMI. Among them, the CPU is connected to the HDMI through the HDMI conversion chip, and the HDMI can connect the computer to the display device (such as a TV, a projector, etc.) through the HDMI cable of the display device to send audio signals and video signals to the display device (collectively referred to as for HDMI signal). [0003] At present, in the operating system driver of the computer, the HDMI conversion chip is only configured once when the operating system is initialized. Therefore, in order to enable the computer to send HDMI signals to the display device, it is necessary to insert the HDMI cable o...
