HX8347 TFT display driver library

The HX8347 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

HX8347 display controller characteristics

Below is a brief introduction to the main characteristics for the HX8347 RGB display controller (seen from a software driver design viewpoint).

For information about the HX8347 driver software support please go to the library description.

HX8347 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
  • The HX8347 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.
  • HX8347 frame buffer organization: 240 RGB pixels on scan line, 320 lines.

Processor interfaces on HX8347

  • HX8347 parallel bus interface
    • Parallel bus types: 8080 bus type and 6800 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 HX8347
    • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 first byte in CS frame contains: device code, DC, RW. 16 or 24 bit transmission frame
    • In SPI bus mode the frame buffer memory can not be read.
  • The bus interfaces are all supported by the HX8347 display driver software package.

Special HX8347 hardware features:

  • A-I variants have slightly different command sets and data formats..
  • 0-180, 90-270 degree frame buffer rotation with hardware support. Portrait mode, landscape mode.
  • Full driver software support.
