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.
