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
