error: 'Keyboard' was not declared in this scope

This sketch runs fine in Aruino 1.0.6 Ide.
But when I compile the same sketch in AtmelStudio Visual Micro it gets "error: 'Keyboard' was not declared in this scope":
Code (C++)
Select All
void setup()
{
	Keyboard.begin();
	delay(2000);
}

void loop()
{
	delay(1000);
	//Keyboard.press(KEY_Y);
	//Keyboard.release(KEY_Y);
}

I am running Teensyduino 1.20 Release Candidate #5 on Aruduino 1.0.6, AtmelStudio 6.2, Visual Micro
Where do I start trouble shooting?

Thank you.

I see you are using a teensy version of the Arduino Ide and as you know you will have selected the speed, keyboard, usb etc from the menus.

In Visual Micro you have entered these settings as defines but it looks like you got the defines wrong. 

In fact F_CPU is also report as missing and the speed unknown. All of the errors relate to the defines being invalid.

I think when you pasted in the defines you did not realize that you had other text selected.

You do NOT need the text Defines=Project: which you have added by mistake

You must simply add project level defines as follows:-

Code
Select All
F_CPU=16000000L;USB_SERIAL;LAYOUT_US_ENGLISH


NOT

Code
Select All
Defines Project:
F_CPU=16000000L;USB_SERIAL;LAYOUT_US_ENGLISH

Thanks for catching that.
So I edited the "Defines - Project" field to correct it, and restarted Atmel Studio, but the same error persists:

Hi,

try clicking "build>clean solution" and then run the build. This will ensure the previous failed build with missing defines is cleared and the compiler cache can start fresh.

Please also post your full sketch code. the error suggests that keyboard.h has been included in the sketch but it can't be resolved so I would like to see the syntax

thanks

Okay great. I think you just need the correct define to tell Teensy you want to use the keyboard (HID) function

use

USB_SERIAL_HID

instead of

USB_SERIAL

I will alter the example so that people get the keyboard by default.

This was working a few days ago, now this error is back:
Quote:
"error: 'Keyboard' was not declared in this scope"

I have checked the following, and they are the same from when the code was compiling:
  • Micro General (Project Global) Defines - Project: F_CPU=16000000L;USB_SERIAL_HID;LAYOUT_US_ENGLISH
  • #include <Keyboard.h> is in the header file and ino file

I also: Build > Clean Solution

The code compiles on Arduino IDE.

What else can I trouble shoot?

Thank you.

Looks like uno board selected not teensy. Select teensy then save project so the setting is retained.

Thank you.  That fixed it Smiley.

I installed/updated to TeensyDuino 1.20 two days ago.
It's in the Verbose Message:
Quote:
"C:\Users\wolf\AppData\Local\VMicro\Arduino\Builds\kb\teensy2\kb.cpp"  -DF_CPU=16000000L -DUSB_SERIAL -DLAYOUT_US_ENGLISH -DVISUALMICRO_COMPILER_VER=1  -DTEENSYDUINO=120

The "Micro Boards" field said "Teensy 2.0" the whole time, so the fix was non-obvious.

The latest release used menus for "board options menus" instead of defines. You should upgrade to the latest Teensy currently 1.23 + Arduino 1.6.4 Ide. Existing project defines can then be removed. Please see the Teensy page and the release notes.

The latest release is especially recommended because it requires zero knowledge to configure (unlike the previous 1.0 system)  Smiley
