Problems solved by technology

[0004] In view of this, it is necessary to control the LEDs for the above two GPIOs. When the GPIOs are changed, the board layer and the Hal layer provide a control of the GPIOs that control the LEDs of the set-top box for the related changes of the GPIOs and the problems that the implementation is cumbersome and the logic design is easy to be confused. method and system

Abstract

The invention relates to a management and control method and system for controlling a GPIO of a set-top box LED. The method comprises the following steps: defining LED attributes and control attributes of the GPIO in advance, then packaging the defined attributes in a preset control variable, sending the packaged control variable to an Hal layer for analysis, initializing the GPIO through the defined attributes, and when an application layer operates the LED, performing management and control on the GPIO by the Hal layer by fast inquiry according to the defined attributes so as to accomplish the operation of the LED. The management and control of the GPIO are very simple and flexible. As the necessary LED attributes and control attributes of the GPIO are defined in advance, when the GPIO controlling the LED changes, only the defined attributes are modified on a Board layer and are sent to the Hal layer for analysis, the logic design is simple, the repetitive work of the Hal layer to continuously set the GPIO is relieved, the CPU processing efficiency is improved, and the control problem of the LED is avoided.

Description

technical field [0001] The invention relates to a digital TV terminal, in particular to a control method and system for controlling a GPIO of a set-top box LED. Background technique [0002] In the LED control of the set-top box, the GPIO (General Purpose Input / Output, GPIO for short) that controls the LED of the set-top box is configured on the Board layer (board layer), and the control of the LED is on the Hal layer (hardware abstraction layer). [0003] Currently, for LED control, a GPIO controls the turning on and off of an LED. Therefore, in terms of software implementation, only the GPIO pin number and logic value of the Board layer are sent to the Hal layer to realize the control of the corresponding LED. When one GPIO is controlled to realize various states of the LED (switch, color, etc.), two GPIOs need to be set at the same time. Two GPIOs controlling the LED will bring great difficulties to the logic implementation of the Hal layer software. When controlling the...
