OK, so I got teensyduino running, etc... but I don't get how to generate a clock wtih that library. Some REAL BASIC help would be appreciated. What exactly do I do?? How exactly to I control the Hz of that signal? What pin exactly am I outputting on?
I installed the libraries you suggested and they give me two options, neither of which are "clock". I get "fanspeed" and "Interrupt". I tried fanspeed. In the code it says the pin is "4". Huh? "4"? B4? F4? D4?. Or physically the 4th pin on the Teensy? I tried that and my scope shows some wave-ish output, but no matter what variables I change in the code, its the same wave.
Thoroughly confused. Which is why I wanted to see BASIC and complete code for generating a clock, so I have some basis for moving forward.
