[GUIDE] Wiring Diagrams: all-in-one board, graceful shutdowns, audio-only board

[hueblo]

I haven't delved into the code yet, maybe @Helder or @hueblo can help?

You give me too much credit @a3k4. I can edit code if I have a good understanding of it but I'm not using teensy. Maybe @popcorn or even weremy himself can help out with that code?

[Helder]

What Teensy are you using? one of the teensies the NON LC version uses Atmega32u4 while the LC version @Wermy used is a different MCU and should work with his code.

If it's the Atmega32u4 version then you can use the code I have in my programming thread in the Other Hardware subforum.

[wermy]

Im using Helders audio board and have followed the Standard wiring diagram (v2.5) to wire the teensy. This is of course different to Wermys set up so the Arduino Project he wrote won't work. I have amended it but its not working for me ill post the code below can anyone take a look and advise please.

Code: Select all

#include <Bounce.h>

#define NUM_KEYS 12

struct Key {
  char keycode;
  Bounce* bounce;
};

Key keys[NUM_KEYS];

Key key(char keycode, int pin) {
  Key *ret = new Key;
  ret->keycode = keycode;
  ret->bounce = new Bounce(pin, 10);
  pinMode(pin, INPUT_PULLUP);
  return *ret;
}

void setupKeys() {
  keys[0] = key('w', 14);
  keys[1] = key('s', 15);
  keys[2] = key('a', 16);
  keys[3] = key('d', 17);
  keys[4] = key('p', 18);
  keys[5] = key('l', 19);
  keys[6] = key('o', 20);
  keys[7] = key('k', 21);
  keys[8] = key('x', 22);
  keys[9] = key('z', 23);
  keys[10] = key('q',24);
  keys[10] = key('e',25);
}

void setup() {
  setupKeys();
  Keyboard.begin();
  //  pinMode(0, INPUT_PULLUP);
}

void loop() {
  for (int i = 0; i < NUM_KEYS; i++) {
    keys[i].bounce->update();
    if (keys[i].bounce->fallingEdge()) {
      Keyboard.press(keys[i].keycode);
    } else if (keys[i].bounce->risingEdge()) {
      Keyboard.release(keys[i].keycode);
    }
  }
}

@warrell What were you trying to modify the code to do and what problems are you having with it? And which Teensy are you using? I haven't tested the code but off the bat I do see on line 32 you're assigning keys[10] for the second time (should be keys[11] there).

@wermy My intention was not to modify the codes function. Only to have it work with Helder's Audio board & teensy wiring diagram (v2.5) on the first page of this topic. I noticed the numbered through holes used in the diagram are different from in your video so assumed (maybe wrongly?) that the code would need to reflect this? The only changes I have made are to some of the key numbers.

When connected to my Rpi2 running RetroPie no inputs are recognised i.e. nothing happens

@Helder Im using the Teensy-LC I have attached a picture as I have it currently for your reference.

Any help is much appreciated, thanks for your patience

[Helder]

If you used Wermy's code like he used in the video then that wiring you have now is incorrect. Follow the video guide and it should work .

[warrell]

Thanks @Helder I think that's what I will do. Is it worth editing the wiring diagrams in this thread to reflect wermy's as I followed those.

[Tamasco]

Why are you using those pins in the Teensy? The last time I took the code from wermys, he was using the first ones. This iis what I´m using, and it works.

Code: Select all

#include <Bounce.h>

#define NUM_KEYS 12

struct Key {
  char keycode;
  Bounce* bounce;
};

Key keys[NUM_KEYS];

Key key(char keycode, int pin) {
  Key *ret = new Key;
  ret->keycode = keycode;
  ret->bounce = new Bounce(pin, 10);
  pinMode(pin, INPUT_PULLUP);
  return *ret;
}

void setupKeys() {
  keys[0] = key('w', 0);
  keys[1] = key('s', 1);
  keys[2] = key('a', 2);
  keys[3] = key('d', 3);
  keys[4] = key('p', 4);
  keys[5] = key('l', 5);
  keys[6] = key('o', 6);
  keys[7] = key('k', 7);
  keys[8] = key('x', 8);
  keys[9] = key('z', 9);
  keys[10] = key('q',10);
  keys[11] = key('e',11);
}

void setup() {
  setupKeys();
  Keyboard.begin();
  //  pinMode(0, INPUT_PULLUP);
}

void loop() {
  for (int i = 0; i < NUM_KEYS; i++) {
    keys[i].bounce->update();
    if (keys[i].bounce->fallingEdge()) {
      Keyboard.press(keys[i].keycode);
    } else if (keys[i].bounce->risingEdge()) {
      Keyboard.release(keys[i].keycode);
    }
  }
}

Because if you follow the wiring diagram on this thread those are the pins used.

Do you mean this one? http://i.imgur.com/gQGaU4j.png

If so then that one seems to be for a Teensy 3.1.

You can use any pins, really. There is a pinout diagram here you can reference: https://www.pjrc.com/teensy/teensyLC.html#pinout

Probably easier just to re-wire it to use the expected inputs though, honestly.

I have a micro SD breakout board from another project, I was thinking of using it on in a GBZ. The pin out is different to this diagram though. I can't seem to see how it cross refers. Image here, can anyone help?
