description: | | ||
The STMicroelectronics STM32 LVDS Display Interface Transmitter handles the | ||
LVDS protocol: it maps the pixels received from the upstream Pixel-DMA (LTDC) | ||
onto the LVDS PHY. | ||
It is composed of three sub blocks: | ||
- LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps its input | ||
pixels onto the data lanes of the PHY | ||
- LVDS PHY: parallelize the data and drives the LVDS data lanes | ||
- LVDS wrapper: handles top-level settings | ||
The LVDS controller driver supports the following high-level features: | ||
- FDP-Link-I and OpenLDI (v0.95) protocols | ||
- Single-Link or Dual-Link operation | ||
- Single-Display or Double-Display (with the same content duplicated on both) | ||
- Flexible Bit-Mapping, including JEIDA and VESA | ||
- RGB888 or RGB666 output | ||
- Synchronous design, with one input pixel per clock cycle | ||
