TileDriver is a board to drive HUB75 type RGB matrix panels from an SPI bus. It contains a framebuffer and interface circuitry to allow slower CPUs like an AVR or PIC to drive the displays.

Project Status

  • 2015-09-16: Received 32x32 video tile and MachXO dev board to prototype this.
  • 2015-09: Started putting idea together to use in the future BRCRD Scoreboard project.

Overview

  • 640x640x24bpp max display size
  • Main data input via SPI at up to 50MHz
    • 256x256x24bpp can update at 30fps
    • 640x640x24bpp can update at 5fps, still fine for static data displays
