NovaVGA - Arduino graphics shield
$24 USD
NovaVGA is available from :
• The MicroNova Store
• Tindie.com
NovaVGA is a low-cost shield board for the Arduino that provides an easy-to-use VGA graphics output. The adapter is controlled via a simple SPI interface from the Arduino (or any SPI-compatible microcontroller.)
NovaVGA keeps a 160x120 frame buffer in SRAM and outputs it to a monitor at an industry standard 640x480 @ 60Hz VGA signal. Meanwhile, the microcontroller is free to write to the SRAM frame buffer at any time via the SPI interface. An Arduino library is provided with several examples.
Video output is 160x120 pixels @ 6-bit color
(2^6 = 64 possible colors)640x480 @ 60Hz physical resolution
(25.175MHz pixel clock)Controlled via standard SPI mode 1 interface
(consumes only three Arduino pins)Arduino library with examples: color palette, Mandelbrot, Tetris and text console
Powered by a Xilinx XC9572XL CPLD.
(User programmable via JTAG interface).
NOTE: NovaVGA does not include header pins.
