TL1771 TFT display driver library

The TL1771 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

TL1771 display controller characteristics

Below is a brief introduction to the main characteristics for the TL1771 RGB display controller (seen from a software driver design viewpoint).

For information about the TL1771 driver software support please go to the library description.

TL1771 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
  • The TL1771 supports TFT screens with a size up to 128 x 160 pixels (WxH)
  • On-chip TFT driver with voltage generator

Frame buffer

  • RGB pixel resolution (bits per pixel): 16-bit.
  • TL1771 frame buffer organization: 128 RGB pixels on scan line, 160 lines.

Processor interfaces on TL1771

  • TL1771 parallel bus interface
    • Parallel bus types: 8080 bus type and 6800 bus type
    • Parallel bus size: 8-bit, 16-bit.
    • Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))
  • Serial bus interfaces on TL1771
    • SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 first byte in CS frame contains: device code, DC, RW. 16 bit transmission frame, (SPI only use 16 bits pr pixel mode)
    • In SPI bus mode the frame buffer memory can not be read.
  • The bus interfaces are all supported by the TL1771 display driver software package.

Special TL1771 hardware features:

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