SSD1327 display driver library

The SSD1327, SSD1327Z, and SSD1327ZB display controllers are supported by the RAMTEX SSD0323 display driver library package.
Full GUI display driver code. Processor and C compiler independent C source code.

SSD1327 display controller characteristics

Below is a brief introduction to the main characteristics for the SSD1327 Grey-level display controller (seen from a software driver design viewpoint).

For information about the SSD1327 driver software support please go to the library description.

SSD1327 device type

• Grey-level color display controller for use in small embedded systems with on-chip frame buffer and OLED screen driver.
• The SSD1327 supports OLED screens with a size up to 128 x 128 pixels (WxH)
• On-chip OLED driver with voltage generator and software controlled LCD contrast regulation.

Frame buffer

• Grey-level pixel resolution (bits per pixel): 4 bit.
• SSD1327 frame buffer organization: 128 Grey-level pixels on scan line, 128 lines.
• Frame buffer storage use 2 pixels in 1 horizontal byte.

Processor interfaces on SSD1327

• SSD1327 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 SSD1327

  • SPI bus: 4-wire: /CS, CD, 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 SSD1327 display driver software package.

Special SSD1327 hardware features:

• 0-180, 90-270 degree frame buffer rotation with hardware support
• Support for screen driver contrast regulation in hardware.
• Full driver software support.
