Arduino Pro (Leonardo Micro)

[supperdd]

Yes i think the keyboard for emulator gba if i want to play games that need analog stick i will play with an external pad ...

I followed the instructions of this post but I block because my arduino asks me the library hid.h but I have them all install and it still will not

[vnman]

don't know about yours board but mine came pre-program as "Leonardo Pro" and with keyboard emulation.

Maybe you can try to test yours without program the thing?

just connect the board to your pc and see what came up in Device Manager (if you using Windows).

As said above I do not use wondows but linux
And the leonardo that I buy on ebay was blank

My buttons Do also have a delay.
I have tried bot sketches and non of them work better
Can anybody help me?

I've started building my GBZ now - Big thanks to [mention=dominator]Dominator[/mention] for sending me the GBZ PCB and some stickers and buttons.

Anyway, I opted to use the Leonardo Micro instead of a teensy, pretty much same size.

I wanted to share my arduino code that I used. I've used this same code on a Retro Arcade Machine Coffee Table I built

Code: Select all

#include <Keyboard.h>

#define BUTTONS 15
int pin_arr[]={2,4,3,5,14,16,9,8,A0,A1,6,7,A2,A3,15};
int keycode_arr[]={218,217,216,215,128,130,32,129,122,176,53,49,112,177,179}; 
// UP,DOWN,LEFT,RIGHT,LEFT-CTRL (Button 1), LEFT-ALT (Button 2),SPACEBAR (Button 3), LEFT-SHIFT (Button 4), Z (Button 5), ENTER (Button 6) (Enter instead of X so can use with other RPi things like raspi-config), Coin/Credit, 1P Start, P (Pause), ESC, TAB
int key_state[BUTTONS];

void setup() {
  Keyboard.begin();
  for (int i=0;i<BUTTONS;i++)
  {
    pinMode(pin_arr[i], INPUT_PULLUP);
    key_state[i] = digitalRead(pin_arr[i]);
  }
}

void loop() {
  for (int i=0;i<BUTTONS;i++)
  {
    key_state[i]=digitalRead(pin_arr[i]);
    if (key_state[i]==LOW) {
      Keyboard.press(keycode_arr[i]); if (keycode_arr[i] == 49) { delay(100); }
    } else {
      Keyboard.release(keycode_arr[i]);
    }
  }  
}

the download also includes an additional header (not included in the compilation as it's for reference only) That lists all the Key Codes.

I hope this is of use to others

Hi, I am having some problems with getting this to work, but i'm a total noob here so i just try to follow the guides step by step as best i can. But i get the following error message

Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Leonardo"

test.ino: In function 'void setup()':

This report would have more information with

enabled in File > Preferences.

I'm using the following code

Code: Select all

//#include <Keyboard.h>
#define BUTTONS 15
int pin_arr[]={2,4,3,5,14,16,9,8,A0,A1,6,7,A2,A3,15};

    } else {
      Keyboard.release(keycode_arr[i]);
    }
  } 
}

If i do not comment out the first line i get this this error:

Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Leonardo"

test.ino:1:22: fatal error: Keyboard.h: No such file or directory
compilation terminated.

Arduino version 1.6.5

Any help i can get is appreciated any more info i should provide then please let me know.

[sqwzy]

so I have been trying for hours now. I'm getting bad button lag, and there as another red led on besides the power.
I'm using Arduino 1.5.6-r2 (it is the only version I have tried that actually lets me compile with no errors.)
can someone help me out. thanks

Hey, can someone tell me where shoud i connect the usb pads from the pi zero (from the usb hub) to the arduino pro board?
On the teensy lc you connect it to VCC D- D+ GND but the pro micro uses other...
Thank you

Please help, I have the same question.

I want to use Arduino Pro Micro, instead of Teensy.
On Teensy board, there are D+ / D- pins for connecting or soldering RPi's USB port.
But, Arduino Pro Micro, they are Tx/Rx,... pins, please tell me how to use those of pins, or any idea else.

Thank you 

Is there a good guide for this? I am seeing conflicting information on how exactly to wire it up. I'd like to directly wire if possible to avoid having having to plug in a USB cable like the poster above did (to reduce space requirement). Do I wire into 5V+, GRD, TX, and RX? I've read some people say that you shouldn't wire directly into 5V+ and that VIN requires 7V. Anyone doing this?
