Arduino Pro (Leonardo Micro)

[winnetouch]

Thanks I'll try figuring it out. Just one more question. How do you redefine the pins? I want to use pin0 on the pro micro. Is there a way to do that?

[myPiZero]

I edited the code to include all the pins on the Arduino pro micro.
I don't know if the extra unused keys might degrade the performance. I use the same code with a smaller arrays of 12 keys only.

Code: Select all

#include <Keyboard.h>

#define BUTTONS 20

int keycode_arr[] =
{
  118,  // PIN0   'v'
  119,   // PIN1   'w'
  120,  // PIN2   'x'
  121,   // PIN3   'y'
  32,  // PIN4   space
  10,  // PIN5   enter

  215,  // PIN6   RIGHT
  217,  // PIN7   DOWN
  216,  // PIN8   LEFT
  218,  // PIN9   UP

  122,  // PIN10  Z
  176,  // PIN11  ENTER
  17,   // PIN12  CTRL
  204,  // PIN13  F11

  112,  // A0     PAUSE
  177,  // A1     ESC

  97,  // A2     'a'

  98,  // A3     'b'

  108,  // A4     (right shoulder - r)
  114   // A5     "l" - left shoulder
};

Thank you. I really appreciate your help

[winnetouch]

Well... I'm back

I don't think I'm doing this right. I modified the key hex codes and uploaded it to my spakrfun pro micro (that doesn't have a pin 11-13 but it continues from 14-16 and then 19-21 si I need a at least pin 16 also )

Also. With they keys that I did modify... They don't seem to work. At least not on my mac. So what am I doing wrong?

Code: Select all

#include <Keyboard.h>

#define BUTTONS 20

int keycode_arr[] =

  26,  // PIN0   'w'
  22,   // PIN1   's'

  7,   // PIN3   'd'
  46,  // PIN4   '.'
  176,  // PIN5  Enter

  28,  // PIN6   y
  27,  // PIN7   x
  6,  // PIN8   c
  25,  // PIN9   v

  20,  // PIN10  q
  8,  // PIN11  e
  17,   // PIN12  CTRL
  204,  // PIN13  F11

  112,  // A0     PAUSE

I modified the code after you saw my comment. Please use the new code.

[winnetouch]

damn it. Either that last code or something I did bricked my pro micro. I can't bring it back to life anymore . The port doesn't show up and doing the double click thing doesn't do anything. Looks like I'm screwed.

sparkfun

[winnetouch]

I found that online yesterday and tried multiple fixes. I don't have the programmer chip so I can't use that method. I tried shorting the ground and reset pins and succeded maybe 2x out of 100 to restart the bootloader but the compiler was never fast enough to load a new code to the chip. The double push doesn't seem to work for me like it should. I did use a wire not a tact switch though.

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

i also am struggling with where to connect my usb, does anyone have an answer to this yet?
thanks

Just checked this out both by eye and with my multimeter, I have not tried it yet, waiting for my usb hub to arrive.

The resistors are tiny on these, some very fine wire will be required to attach to the end of them.

I managed to fix my sparfun pro micro but the code still doesn't work for me. I'm testing it on my laptop. I copied the code in to my arduino software and uploaded it to my sparfun pro mini. Then I opened up a text editor and tried pressing the buttons. Only the v and y pins worked and even then the y pin was not the correct pi on the sparkfun pro micro. It should be pin 10 but it acted like pin 4.
