- Description: Generate VGA output which shall display the pattern similar to Ishihara Plates
- GitHub repository
- Clock: 0 Hz
How it works
Generates VGA output for displaying pattern similar to Ishihara plates used for conducting a color blindness test. (Disclaimer: Note that this is not an approved medical test and test setup. The pattern generated is for purely experimental purpose.)
How to test
This project will work out of the box. Just connect a VGA display via TinyVGA PMOD.
