WB_VGA - Configurable Wishbone Display Driver
Figure 1. WB_VGA - Configurable Wishbone Display Driver.
The Wishbone Display Driver (WB_VGA) is a configurable component that can be setup to operate as any of the three 32-bit VGA Controllers available in Altium Designer, and summarized as follows:
VGA32 | – | standard 32-bit VGA Controller with configurable color quality (1,2,4,8bpp), support for screen resolution up to 800x600 and screen refresh rate of up to 75Hz. |
VGA32_16BPP | – | as per the standard 32-bit VGA Controller, but with fixed 16bpp color quality. |
VGA32_TFT | – | this 32-bit VGA Controller is specifically used to interface to a TFT panel. It supports a fixed TFT screen resolution of 240x320 and a fixed refresh rate of 50Hz. Its color quality is fixed at 16bpp. |
Features at-a-glance
- Completely configurable from the schematic sheet
- Configurable as one of three 32-bit VGA Controllers:
- VGA32
