![]() ![]() Shop around for buttons, since they are expensive, and you may want to get some samples before buying masses of them only to find they are too clicky, fragile, can't be soldered or some other 'feature'. Other options include just using two Teensy's (so two joysticks as seen by your PC) to keep the wiring and code simpler and saner. With your current plan there will be a rats next of wires going into the teensy which will work, but be tedious, especially since you will be soldering to pads on the underside going above pin 23 so some tricky soldering there. If you have the right sort of buttons you can just mount them at 45 degrees and have a reasonably simple wiring arrangment. This complicates the code a bit, but means your wiring consists of a run across each row, and a run up each collumn. If you want to make it easier to wire, try the library Unsure on pin 13 as an input, as noted there. Your code should work for what you are trying to do though you may find you need to bump up the numbers to clear your existing joystick button 1 etc. to high (not pressed - voltage from pullup resistor) Ctrl-Up / Ctrl-Down: Set the switching distance of automatic reversal. Ctrl-Left / Ctrl-Right: turn towards the automatic reversal, reversing automatic start manually. rising = low (pressed - button connects pin to ground) This level is accessible by pressing the left Ctrl key. to low (pressed - button connects pin to ground) falling = high (not pressed - voltage from pullup resistor) Update the Joystick buttons only upon changes. faster than the buttons could be pressed and released. delays in loop(), so this runs repetitively at a rate ![]() PinMode(13, INPUT_PULLUP) // Teens圓2 LED, may need 1k resistor pullup The scheme is called "active low", and it's backwards, but using the on-chip pullup resistors is very LOW for "on", and HIGH for "off" may seem because the pullup resistor connects to +5 volts inside the button is pressed, the pin reads LOW because the button The pushbuttons connect from each pin to ground. Configure the pins for input mode with pullup resistors. it makes detecting changes very simple.īounce button1 = Bounce(1, 10) // 10 = 10 ms debounce timeīounce button2 = Bounce(2, 10) // which is appropriate forīounce button3 = Bounce(3, 10) // most mechanical pushbuttons automatically deals with contact chatter or "bounce", and Create Bounce objects for each button. This example code is in the public domain. You must select Joystick from the "Tools > USB Type" menu ![]()
