A Better Way to Display – VGA
We’ve been on quite a journey so far. We have come across a lot, starting from understanding basic digital circuits to designing a calculator. We’ve interfaced with external components such as a temperature sensor and microphone. We’ve looked at computer math and even advanced math topics such as floating point operations, pipelined design, and parallelism. However, up until now, we’ve been limited to displaying information using LEDs, single color or RGB, as well as the seven-segment display. We are quite capable of performing operations and displaying limited information, as we have demonstrated with our temperature sensor and calculator. The Nexys A7 offers an additional output that can provide us with an almost unlimited method of displaying information, the Video Graphics Array (VGA) connector. The VGA connector on the Nexys A7 can display resolutions of up to 1600x1200, with up to 212 or 4,096 colors. What allows...
