R61580 TFT display driver library

The R61580 display controller is supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

R61580 display controller characteristics

Below is a brief introduction to the main characteristics for the R61580 RGB display controller (seen from a software driver design viewpoint).

For information about the R61580 driver software support please go to the library description.

R61580 device type

• COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
• The R61580 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.
• R61580 frame buffer organization: 240 RGB pixels on scan line, 320 lines.

Processor interfaces on R61580

• R61580 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 R61580

  • 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 R61580 display driver software package.

Special R61580 hardware features:

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