Color Computer cassette port Input used as game controller
I've begun experimenting with using the Color Computer cassette port as a game controller input. The idea is based on the late, great Steve Bjork's Audio Spectrum Analyzer (1981). First of all, a big shout-out goes to Chet Simpson for his work disassembling and posting the code with notes on GitHub ( CoCo-AudioSpectrumAnalyzer ). Thanks Chet. I reduced the code to a subroutine that can be used to sample the cassette audio input, measure the width of the frequency, compare to a table and return a frequency value. The following demo is an example of how I envision using this subroutine: Inspiration for the Speed Racer demo: Speed Racer - Button Tutorial Examples of an electric keyboard, instead of the phone APP, being used as sound inputs: I wrote the APP in Swift on Xcode ( https://developer.apple.com/xcode/ ). Xcode is a free to download from Apple. You can develop an APP and 'test' it on your phone without having to upload it to the A...
