The Arduino Graphics Interface — Part 1

By Edward Andrews    View In Digital Edition  


Would it be possible to replace a half dozen racks of circa 1975 minicomputer hardware with one of today’s $50 credit-card sized computers?

YES!  What resulted is the Arduino Graphics Interface, or AGI for short. With AGI, you can transform a leftover analog oscilloscope into a high resolution computer graphics display and gain valuable insights into computer graphics, digital-to-analog conversion (ADC), and advanced Direct Memory Access (DMA) hardware and software techniques. It’s easy to add a real time clock (RTC) module and interactive controls to turn the AGI platform into a “CRT CLOCK” or other high resolution computer graphics display device.

Here, we’ll focus on the overall concepts, circuit design, and hardware fabrication.
