Red appears blue, blue appears red, or colors look like a camera negative.

"Tick! The registers!" Elara shielded her eyes. "We're writing to the wrong address space! We're hitting the command register instead of the data RAM!"

Based on empirical data from controlled tests, the header follows this structure:

She sat back down. The solution wasn't in the hex code. The hex code was perfect. It was the translation layer. The image2lcd tool had given her a bucket of water, but she was trying to pour it into a cup that was upside down.

To help find the right setup, what and LCD screen model are you using? I can provide a free code snippet or recommend the exact free conversion tool settings for your hardware.

Include the generated header file in your Arduino/STM32 project:

// Sample array structure generated by Image2Lcd (RGB565) const unsigned char gImage_logo[12800] = 0xFF, 0xFFFF, 0x00, 0x00, // ... Your exported data here ; void LCD_DrawImage(uint16_t x, uint16_t y, uint16_t width, uint16_t height, const unsigned char* image_array) uint32_t i; uint32_t total_bytes = width * height * 2; // 2 bytes per pixel for RGB565 // Set the boundaries on the screen LCD_SetWindow(x, y, x + width - 1, y + height - 1); // Prepare LCD to receive pixel data (RAM Write Register) LCD_WriteCommand(0x2C); // Set DC to high to prepare for massive data stream LCD_DC_HIGH(); LCD_CS_LOW(); // Loop through the Image2Lcd array and push bytes to the SPI register for(i = 0; i < total_bytes; i++) SPI_Transfer(image_array[i]); LCD_CS_HIGH(); Use code with caution.

Select Horizontal or Vertical scanning (depends on your LCD driver library). 3. Generate and Save Code

Automatically generating the .c or .h files ready to be included in your C++ code. The Trial Version Limitation

The registration code for the software (v3.2 and similar versions) is typically provided by manufacturers like Good Display Keyestudio to remove watermarks from converted images. The registration code is: 0000-0000-0000-0000-6A3B How to Register: application.

The output generated by Image2LCD typically looks like a standard C function. Below is an example of what a snippet looks like for an ILI9341 controller:

In your main application loop, call the generated function before attempting to draw pixels.

| bit6 | bit5 | bit4 | bit3-2 | bit1-0 | |---|---|---|---|---| | 0: left→right | 0: high→low | 0: WORD order normal | reserved | 00: horizontal scan | | 1: right→left | 1: low→high | 1: WORD order reversed | | 01: vertical scan | | bit7: top→bottom / bottom→top | | | | 10/11: mixed modes |
