Embodiment Construction

[0021] see figure 1 , the method for displaying a picture of an electronic device proposed in this application includes the following steps.

[0022] Step S10: The electronic device adopts LVGL (Light and Versatile Graphics Library, lightweight general-purpose graphics library) as the GUI system framework, adds a PNG format image decoding function to the LVGL system framework, and connects to the drawing interface of the LVGL system framework. The LVGL system framework has the characteristics of small amount of code and easy UI (user interface, man-machine interface) development, and can be stored in a 16MB flash memory.

[0023] In the existing LVGL system framework, the picture is saved in a true color (true color) bitmap (bitmap) format and saved as an array (array) data structure in C language. When this saved image is used as an input source, the LVGL system framework does not need to be decompressed, and can be directly read into the memory and displayed by the drawing ...

Abstract

The invention discloses a picture display method of electronic equipment. The method comprises the following steps: S10, the electronic equipment adopts a lightweight general graphics library LVGL asa graphical user interface GUI system framework, adds a decoding function of a picture in a PNG format in the LVGL system framework, and is in butt joint with a drawing interface of the LVGL system framework; S20, the electronic equipment changes the picture into a transparent PNG8 format, stores the picture as an array data structure of a C language, and stores the array data structure into the electronic equipment as a part of system firmware; and S30, the electronic equipment decodes the picture with the transparency in the PNG8 format and displays the picture on a screen of the electronicequipment line by line. The LVGL system framework has the characteristic of small code quantity, but does not support decoding of a picture in a PNG format. A PNG picture decoding function is added inthe LVGL system framework, and meanwhile, the pictures in the system firmware are stored in a PNG format, so that the storage space of the system firmware of the electronic equipment is reduced to the greatest extent. The volume of the system firmware of the electronic equipment can be reduced to the greatest extent.

Description

technical field [0001] The present application relates to a method for displaying pictures of an electronic device using an embedded system, in particular to a method for displaying a picture of an electronic device using an embedded system with limited storage space. Background technique [0002] A children's watch is a typical electronic device with an embedded system. Children's watches are mainly used to realize the positioning function, and the positioning function mainly relies on satellite positioning technology such as GPS (global positioning system, global positioning system), base station positioning technology of mobile communication network, WiFi (wireless network) positioning technology, etc. Some children's watches only support 2G mobile communication networks, while others support up to 4G mobile communication networks. The modem (modulator-demodulator, modem) code of the 4G mobile communication network is larger than the modem code of the 2G mobile communica...
