Image extraction

Introduction

When developing embedded microcontrollers, it is necessary to use LCD/OLED to display an image. The most direct and simple way is to use the corresponding tools to convert the image into corresponding data points (actually a 2D array), and then use the corresponding code to display the array on the LCD/OLED display screen according to a certain timing.

Operation Steps

1. Click to download Image2Lcd tool
2. Double-click to enter the tool interface

3. Open the image to be extracted (taking the image of the 1.47inch LCD Module as an example)

Parameter setting

Output data type: C array (*.c)
Scanning mode: Vertical scan
Output grayscale: 16-bit true color
Maximum width and height (depending on the actual aspect ratio of the image): 172x320
Output image adjustment: Default settings are fine, check the box for color inversion if needed
Click 16-bit color: color bits RGB565, color data arrangement RGB

4. Set the parameters and then choose Save

The path and name are set by the user
The file type is .c
After saving, an array will be generated, ctrl+A will select all

Copy it to the Image.c file

And declare it in Image.h

Finally call it in the main function, then map to the screen
