Overview

Print BMP File from SD Card (FAT16/FAT32)

This procedure prints a BMP file from an SD card formatted with FAT16 or FAT32. The BMP file must meet specific requirements as no image processing is performed.

BMP File Requirements

The image must be smaller than the screen width and height.
The color depth should be 16-bit RGB (565).
The row direction should be bottom to top (default).
No compression.

You can convert images to the correct format using online tools, such as this one.

Alternatively, you can use the included SdCardWriteRGB565 library tool to convert and upload the BMP file to the SD card.

Example

TftBmpFromSD("PIC001.BMP", 0,0)

Note: No need to initialize the SD card with File_Init() before using this command.
