if you are getting ceros, the most probably couse it's the library for the IR. Reinstall or updeate the library, sometimes you have to reinstall more than one time. That should work.
About media keys, the keyboard library doesn't have media keys funccionallity, so you need to use another one. This one worked for me https://github.com/NicoHood/HID
after you ...
It is indeed possible and also without the requirement to modify the Arduino environment itself. Just register an HID descriptor for the "report ID" for "Consumer Control" (the code is 4 (constant kHID_ReportID_ConsumerControl), where the "report ID" code for keyboard and mouse are 2 and 1, respectively):
static HIDSubDescriptor ...
The Arduino Uno cannot use the Keyboard library. The microcontroller needs to have a native USB interface. The Uno uses the Atmega328p, which does not have one.
You can use the Arduino Micro or Arduino Leonardo for this.
For more experienced hackers: If you need to use the Uno, but still want to use extended USB capabilities (more than USB to Serial), it ...
There does seem to be a method called SetReport in the USBHID class, which looks like it takes the same arguments, which I'm trying to use.
The method arguments of the new SetReport() method aren't quite the same and some are in a different order.
The old method signature was:
uint8_t setReport( uint8_t addr, uint8_t ep, unsigned int nbytes, uint8_t ...
The root problem is that you send each several ms new key event and on receiver each time you get this event, you call Keyboard.press and right away Keyboard.release. So, it behaves as several key press-releases.
At sender side you should send 2 types of events:
Key pressed (and which button)
Key released (and which button)
At receiver side you should
if you have some knowledge in Java or Python you can interface your Arduino board to PC, through Arduino's SerialPort.
When Arduino sends a byte, for example, 0xAB, your Java or Python script sends a fake key-press event.
I hope this can help. Good luck!
I am not sure I have the answer to your problem, just a collection of
observations that hopefully steer you in the right direction.
According to your nopaste link, when you send "ON", the first four
keyboard events received by xev are: press(Shift_L), press(O),
release(Shift_L), release(o). One may notice that there is no point in
releasing the ...
As a novice, I would like to create a small breadboard with 5 items on it. 3 toggle buttons, and two constant spin (ie. no stop at 360 degrees) knobs.
Those knobs are called "Rotary Encoders".
Is then like the bottoms to send what ever key stroke (single key pee click) to the pc as if it was from a keyboard (maybe even a shift+key?)
Then you ...
The USB keyboard protocol has no concept of characters. It doesn't know and doesn't care what character a key represents. Instead each code represents the location of the key on the keyboard, and it's down to the software on the computer to map those locations into characters through its own keyboard map.
So the Arduino has to do the opposite when you want ...
It turns out there is a library that can be added to compile the media and system functions for USB keyboard connection into the Leonardo, as well as other Arduino modules. It is available through 'tools','library manager'; it is HID-project by NicoHood. There is an example program called "system example" at github to test it for for wake and sleep....
For completeness I am posting this answer. You can produce a UK backslash keystroke event by using something like
#define KEY_BSLASH 0xEC
This was found rather more empirically than analytically so is not an especially informative result, but it might be of some use to others creating non-ANSI keyboard layouts using Arduinos.
The twisty click per degree thing is called a rotary encoder.
You can already send serial commands to a computer, so to keep it simple, I'd try to find a way of turning the serial commands into a keyboard click.
Welcome to ASE.
Communication between the PC and the Arduino Pro Micro happens through the USB, unlike the Arduino Uno and Mega, which use the RX and TX lines.
In your case, the USB pins of the Micro are used to communicate with the PC. Hence, the RX and TX pins are available for digital input and output operations.
Using TX and RX on a 32U4 does not affect PC communication. It uses a competent different communication channel.
You can use those pins for digital operation with no problems, you just won't be able to use Serial1 for communication with serial peripherals.
Keyboards cannot be used quite like you wish - the keyboard will send a key (scan) code when a key is pressed and then repeat that code if the button continues to be pressed. There is a different code sent when the same key is released.
The scancode for key release is obtained from it by setting the high
order bit (adding 0x80 = 128). Thus, Esc press ...
First you'll need to define how you plan to inject the new input signal, into the data "packets" as a spoof of controller signals, or just jumping the switches?
In the context of any modern gaming console, it could be detected. Easily. Consoles and controllers use any number of proprietary protocols which sync.commands to improve response and ...
In your particular case, the double quote is to be entered (using the Spanish keyboard layout) by Shift + the physical key labelled 2. On a US keyboard, Shift + the physical key labelled 2 is "@".
Thus, this simply will get the desired result (the Arduino library assumes a US keyboard layout):
Keyboard.print("echo @This is a demo@");
