ILI9340 TFT display driver library

The ILI9340 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

ILI9340 display controller characteristics

Below is a brief introduction to the main characteristics for the ILI9340 RGB display controller (seen from a software driver design viewpoint).

For information about the ILI9340 driver software support please go to the library description.

ILI9340 device type

• COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
• The ILI9340 supports TFT screens with a size up to 240 x 320 pixels (WxH)
• On-chip TFT driver with voltage generator

Frame buffer

• RGB pixel resolution (bits per pixel): 16-bit, 18-bit.
• ILI9340 frame buffer organization: 240 RGB pixels on scan line, 320 lines.

Processor interfaces on ILI9340

• ILI9340 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 ILI9340

  • SPI bus: 4-wire: /CS, DC, SDIN, SCLK.
  • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 uses a 9 bit byte frame where first bit is DC
• The bus interfaces are all supported by the ILI9340 display driver software package.

Special ILI9340 hardware features:

• 0-180, 90-270 degree frame buffer rotation with hardware support. Portrait mode, landscape mode.
• Full driver software support.
