Display a color test pattern on the FLEX's VGA display VGAtest.zip (1.102 Mb) This circuit, programmed into the FLEX10K, causes the UP2 board to display a test pattern consisting of a repeating pattern of horizontal color bands (black, blue, green, cyan, red, magenta, yellow, white) on a standard monitor connected to the VGA display port. You could use this circuit as a starting point for projects that use the VGA display. |

Diagonal test pattern using modular VGA driver VGA_example.zip (486.617 Kb) This VGA example is similar to the previous one, except that the main part of the VGA driver circuitry is encapsulated into a reusable VGA_driver module, which is used in the VGA_example file to generate a diagonal test pattern. |

RGB color mixing demo VGA_RGB_demo_v2.zip (614.855 Kb) This demo allows the user to manually turn on and turn off overlapping regions of red, green, and blue using three DIP switches. This allows the user to see how RGB color mixing works. Version 2 treats the switch inputs as active-high, which seems more natural for the DIP switches. |
