My IDE shows, "Error compiling" when trying to verifiy my code.

[Pastyguy]

I'm using the trinket to as a keyboard(trying to at least), but my problem is just with the IDE. I try to install the the library by sketch>inlcude library>add .zip then returns all clear.
Problem occures when i try to varifiey the code it, and it returns with this error message

"Arduino: 1.6.4 (Windows 7), Board: "Adafruit Trinket 8MHz"

Build options changed, rebuilding all

TrinketKeyboardExample.ino:6:29: fatal error: TrinketKeyboard.h: No such file or directory
compilation terminated.
Error compiling.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

My code from the library im trying to load.

/*
TrinketKeyboard example

#include <TrinketKeyboard.h>

#define PIN_BUTTON_CAPITAL_A 0
#define PIN_BUTTON_STRING    2

void setup()
{
  // button pins as inputs
  pinMode(PIN_BUTTON_CAPITAL_A, INPUT);
  pinMode(PIN_BUTTON_STRING, INPUT);

  // setting input pins to high means turning on internal pull-up resistors
  digitalWrite(PIN_BUTTON_CAPITAL_A, HIGH);
  digitalWrite(PIN_BUTTON_STRING, HIGH);
  // remember, the buttons are active-low, they read LOW when they are not pressed

  // start USB stuff
  TrinketKeyboard.begin();
}

void loop()
{
  // the poll function must be called at least once every 10 ms
  // or cause a keystroke
  // if it is not, then the computer may think that the device
  // has stopped working, and give errors
  TrinketKeyboard.poll();

  if (digitalRead(PIN_BUTTON_CAPITAL_A) == LOW)
  {
    // this should type a capital A
    TrinketKeyboard.pressKey(KEYCODE_MOD_LEFT_SHIFT, KEYCODE_A);
    // this releases the key (otherwise it is held down!)
    TrinketKeyboard.pressKey(0, 0);
  }

  if (digitalRead(PIN_BUTTON_STRING) == LOW)
  {
    // type out a string using the Print class
    TrinketKeyboard.print("Hello World!");
  }
}

"

Id really appreciate the help. Thanks!

I am having a similar issue although this one pertains to the TrinketFakeUsbSerial library. I use the exact same demo code displayed in the tutorial however I receive this error:

I also had this error for the TrinketFakeUsbSerial library. Seems that only the usbdravasm165.inc file is included in the package. Downloaded the file from https://raw.githubusercontent.com/digistump/DigisparkArduinoIntegration/master/libraries/DigisparkKeyboard/usbdrvasm16.inc

However, now I get:

Hmmm... are you using the Pro Trinket or just the regular Trinket? If you're using the pro, you have to actually use FTDI. That was my problem, don't know if it's yours too.

[elwin1234]

Hi,

Thanks! Yes, I also found that it worked using the trinket and not with the trinket pro. Thanks for the FTDI tip.

@Pastyguy Looks like you haven't installed the library correctly. Make sure there is a TrinketMouse directory in your libraries directory. README.md mentions this very briefly. A more detailed explanation can be found here: https://www.arduino.cc/en/Guide/Libraries#toc5

I downloaded the library and try to run it, and did not make any changes in the code.
I receive this error:

Did you manage to find the solution?
