Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] refer to figure 1 , an embodiment of the button extension method of the present invention, comprising:

[0051] S1, configure the first pin as GPIO mode;

[0052] S2, when detecting that the first pin is triggered, identifying the triggered first pin based on the GPIO pattern;

[0053] S3. Obtain a key value corresponding to the triggered first pin, where the key value corresponds to a key function.

[0054] In the above step S1, the above-mentioned first pin is a data pin (Data pin) on the data interface, and the above-mentioned data interface can be a screen interface on the terminal (or other electronic products). It is worth mentioning that, usually, the screen interface There are many data interfaces and data pins reserved on the screen, and many data interfaces are not used. Therefore, the above-mentio...

Abstract

The present invention discloses a key extension method, system and terminal. The method includes: configuring a first pin as a GPIO mode; when detecting that the first pin is triggered, identifying the triggered first pin based on the GPIO mode pin; obtain the key value corresponding to the first pin that is triggered, where the key value corresponds to the key function. By configuring the first pin as GPIO mode, the first pin has the functions of input and output, that is to say, the first pin acts as a key interface pin that can execute input / output instructions, which changes the first Originally, the pins could only simply realize the state of data transmission, and then through this software configuration method, the demand for third-party electronic components was reduced, and the button expansion was realized without adding a third-party IC, which improved resource utilization. Reduce hardware costs.

Description

technical field [0001] The present invention relates to the field of electronic products, in particular to a key extension method, system and terminal. Background technique [0002] Today, when smart products are rampant, there is still a strong demand for functional products in some countries or regions. In order to meet the performance requirements of customers, many manufacturers have to use relatively cheap smart product platforms to develop functional products. [0003] For example, a smartphone is developed into a feature phone: a smartphone generally only needs a few buttons such as a power button and a volume button, and in order to save hardware resources, only the interface pins corresponding to these buttons are assembled; a feature phone requires a power button , volume keys, number keys and more than 20 keys, so the development of smart products into functional products needs to face the resource challenge of key expansion. To increase the number of buttons, t...
