ILI9486 TFT display driver library

The ILI9486 and ILI9486L display controllers are supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

ILI9486 display controller characteristics

Below is a brief introduction to the main characteristics for the ILI9486 RGB display controller (seen from a software driver design viewpoint).

For information about the ILI9486 driver software support please go to the library description.

ILI9486 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
  • The ILI9486 supports TFT screens with a size up to 320 x 480 pixels (WxH)
  • On-chip TFT driver with voltage generator

Frame buffer

  • RGB pixel resolution (bits per pixel): 16-bit, 18-bit.
  • ILI9486 frame buffer organization: 320 RGB pixels on scan line, 480 lines.

Processor interfaces on ILI9486

  • ILI9486 parallel bus interface
    • Parallel bus types: 8080 bus type
    • Parallel bus size: 8-bit, 16-bit, 18 (32)-bit.
    • Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))
  • Serial bus interfaces on ILI9486
