Detailed Description

template<typename RGB_T = RGB565>
class tinygpu::DeviceOutput< RGB_T >

Hardware abstraction for writing framebuffers to SPI-based color displays.

DeviceOutput provides a unified interface for sending RGB565 framebuffer data to common embedded display controllers (ST7735, ST7789, ILI9341, HX8357) using the Arduino SPI API.

Features:

• Handles X/Y offsets for displays that require them (via driver)
• Supports configurable color order (RGB/BGR) via RGB565
• Initialization sequence and address window logic delegated to driver
• Optional hardware reset pin (via driver)
• Efficient bulk framebuffer transfer

Usage: DeviceOutput out(new ILI9341Driver(spi, cs, dc, rst), 240, 320); out.writeData(framebuffer);

Note

For color order, set RGB565::setColorOrderBGR(true/false) as needed for your display, before creating any data.
