When developing a display driver in embedded systems. How are typically framebuffers handled in display drivers?For context, I am developing a display driver that takes a pixel, height, and width that is a std::array<std::array<pixel, height>, width>. Where pixel is a struct that represents our pixel format let's say a uint8_t called rgb.How are typically drivers handle writing data from these framebuffers to the display? Specifically the driver. Not the operations that API the developer would use on the application side. Application-side meaning the draw functions such as draw_line, draw_pixel that would be handled on the application side. Rather more on the driver-specific details on how the driver manages the framebuffers and how the driver sends that data to the display. For example, if I were to have a std::array<std::array<uint8_t, height>, width> that represented our framebuffer, and let's say I wanted to develop a driver for the ILI9341 display. Can you show me a C++ example in detail on framebuffers and how they would be written, read, andd showing those pixels on the display.
