R61509 TFT display driver library

The R61509 and R61509V display controllers are supported by the RAMTEX S6D0129 display driver library package.
Full GUI display driver C source code. Processor and C compiler independent.

R61509 display controller characteristics

Below is a brief introduction to the main characteristics for the R61509 RGB display controller (seen from a software driver design viewpoint).

For information about the R61509 driver software support please go to the library description.

R61509 device type

  • COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
  • The R61509 supports TFT screens with a size up to 240 x 432 pixels (WxH)
  • On-chip TFT driver with voltage generator

Frame buffer

  • RGB pixel resolution (bits per pixel): 16-bit, 18-bit.
  • R61509 frame buffer organization: 240 RGB pixels on scan line, 432 lines.

Processor interfaces on R61509

  • R61509 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 R61509
    • 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 R61509 display driver software package.

Special R61509 hardware features:

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