For the code to work correctly on your screen, the scan mode selected in Image2Lcd must match your LCD controller's register settings.
The Image2LCD register code is a tool used for converting images into LCD display codes. Here are some good features about it:
The MCU configures registers defining the active drawing region (Column Address and Page Address).
A web-based tool optimized for the Light and Versatile Graphics Library (LVGL) that outputs production-ready C arrays for TrueColor, indexing, or alpha-channel formats.
Limits the maximum output resolution of the image (often restricted to small sizes like 32x32 pixels).
The Image2LCD register code work has various applications in:
Without rotating source image, Image2LCD can alter register 0x36 to achieve 90°/180°/270° rotation at the hardware level – saving memory and processing time.
：SPI传输速率与LCD控制器的接收能力不匹配，或DMA传输长度未对齐。
The checkbox "MSB First" (Most Significant Bit) determines whether the High Byte or Low Byte is output first.
Image2LCD is a software tool that takes an image file as input and generates a corresponding LCD display code. The generated code can be used to display the image on an LCD screen. The software supports various image formats, including BMP, JPEG, and PNG.
The image2lcd register code had worked. The gate was open, the project was alive, and Leo could finally go to sleep. To help you with your project or continue the story:
lcd_reg_t lcd_init_sequence[] = 0x00, 0x01, // Example: Software reset 0x01, 0x2C, // Driver output control 0x03, 0x28, // Entry mode // ... more registers from Image2LCD ;
Leo held his breath. He opened the registration window in Image2Lcd. The small box blinked at him, demanding the key. With shaking hands, he typed in the characters one by one, double-checking every '0' and 'O'. He clicked .
: Launch Image2LCD and click the "Register" button on the main interface.
