A high-performance C++ framebuffer copy driver for SPI-based LCD displays (e.g. ILI9341, ST7789) on Raspberry Pi A/B/2/3/4/Zero, achieving up to 60fps via optimized DMA-driven SPI transfers. It relies on the deprecated DispmanX API and is now considered archived, as Raspberry Pi 5 and newer distros use the KMS stack instead.
Use cases
- drive an Adafruit PiTFT ILI9341 SPI display on a Raspberry Pi
- get 60fps on a Waveshare 3.5 inch SPI LCD for RetroPie
- mirror the Raspberry Pi framebuffer to a small GPIO-connected TFT screen
- reduce tearing and latency on SPI LCD displays for retro gaming handhelds
- set up a lightweight display for a headless Raspberry Pi Zero project
When to choose
- you run RetroPie or a similar setup on Pi 0-4 with an SPI TFT display and need smooth 60fps updates
- you want a free, MIT-licensed display driver with low CPU overhead via DMA
- your project is frozen on an older Raspberry Pi OS with DispmanX available
When to avoid
- you use Raspberry Pi 5 or a recent distro where DispmanX is unavailable
- you need a maintained driver - the project is explicitly stale and unmaintained since Feb 2024
- you use HDMI or DPI displays rather than SPI LCDs
