UC1682 LCD display driver library

The UC1682 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

UC1682 display controller characteristics

Below is a brief introduction to the main characteristics for the UC1682 RGB display controller (seen from a software driver design viewpoint).

For information about the UC1682 driver software support please go to the library description.

UC1682 device type

• COG RGB color display controller for use in small embedded systems with on-chip frame buffer and LCD screen driver.
• The UC1682 supports LCD screens with a size up to 80 x 104 pixels (WxH)
• On-chip LCD driver with voltage generator and software controlled contrast regulation.

Frame buffer

• RGB pixel resolution (bits per pixel): 16-bit.
• UC1682 frame buffer organization: 80 RGB pixels on scan line, 104 lines.

Processor interfaces on UC1682

• UC1682 parallel bus interface

  • Parallel bus types: 8080 bus type and 6800 bus type
  • Parallel bus size: 8-bit.
  • Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))

• Serial bus interfaces on UC1682

  • 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
  • I2C bus: 2-wire: SDIN, SCLK
• The bus interfaces are all supported by the UC1682 display driver software package.

Special UC1682 hardware features:

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