Add the following snippet to your HTML:. Keyboard, mouse, game controller, Midi controller, you name it! Read up about this project on. What if I could just plug a keyboard or a Midi controller? That would be so much easier I didn't know that it was possible!

Thanks to Circuit Home device we can do that. EDIT: Circuitathome website as been replaced so here is the original link from internet archive. Before we plug our USB host to our microcontroller, we will have to fix some issues or it won't work. This means your USB devices will be powered with 3. You will have to cut this trace, to fix this. I used a small screw driver to do this, but you probably should use a small cutter instead.

OK, I hope you didn't break your board! Now it is time to plug it! I run into an issue where the USB Host set my Wemos Mini in firmware flashing mode, which stop the sketch from running.

In order to change the SS pin, we need to change a line in the library. Open UsbCore. OK, we are almost done, if you try to compile an example from the library, it will not works. It is because the library is not compatible with Arduino ESP 2. Note: You can't hot-plug your USB device at least in the examplesyou need to reset the board each times you unplug, plug your device.

I didn't manage to make my mouse works.We are still shipping! When you place an order, we will ship as quickly as possible. Thank you for your continued support. Track My Order.

You could make just about any input device you want into a controller for your computer programs or games. What if you could do it with one line of code, inside the comfy confines of Arduino?

Well, say hello to my micro friend: the SparkFun Pro Micro! What is HID you might ask? It's one of the many defined USB device classes.

Plug Any USB Device on an ESP8266

You might be holding an HID device in one hand right now, while your other hand is hovering over another. Fortunately for us, Arduino exists, and with the release of 1. Unfortunately, that HID stuff is somewhat tucked or even locked away from us. The goal of this tutorial is to explain how to use the Arduino HID library, so you can get the most out of your Pro Micro.

So lets pop the hood!

I stress "simple" at the header of this section, because that's what it is. And that's a great thing! That's it. You don't need to include any libraries or anything, just pull out any of those functions. After a Keyboard. What your computer does with that character, or string of characters, is entirely dependent on what program it's running at the time. If you have a text editor open and active, it'll print it out there.When you hear the word Thumb Joystickthe first thing that comes to mind is the game controllers.

They are mainly used for playing games, although in DIY Electronics, there are a lot of fun things you can do with it. It is a self-centering spring loaded joystick, meaning when you release the joystick it will center itself. The goal of the joystick is to communicate motion in 2D 2-axis to an Arduino. This is achieved by housing two independent 10K potentiometers one per axis. These potentiometers are used as dual adjustable voltage dividers, providing 2-Axis analog input in a control stick form.

The potentiometers are the two blue boxes on the sides of the joystick. We will discuss how they actually work, a little later. This joystick also contains a switch which activates when you push down on the cap. The switch is the small black box on the rear of the joystick.

If you push down on the cap, you can see a lever pushing down on the head of the switch. The lever works no matter what position the joystick is in. This can be little tricky, but thanks to the design of the joystick consisting of two potentiometers and a Gimbal Mechanism.

Create a Joystick Using the Arduino Joystick Library 2.0

When you rotate the joystick, the thumb handle moves a narrow rod that sits in two rotatable slotted shafts Gimbal. One of the shafts allows motion in the X-axis left and right while the other allows motion in the Y-axis up and down. Tilting the stick forward and backward pivots the Y-axis shaft from side to side.

Tilting it left to right pivots the X-axis shaft. When you move the stick diagonally, it pivots both shafts. A potentiometer is connected to each joystick shaft that interprets the position of the rod as analog readings. Moving the slotted shafts rotates the contact arm of the potentiometer. In other words, if you push the stick all the way forward, it will turn the potentiometer contact arm to one end of the track, and if you pull it back toward you, it will turn the contact arm the other way.

This change can be read by an Arduino analog pin using ADC. As the Arduino board has an ADC resolution of 10 bits, the values on each analog channel axis can vary from 0 to So, if the stick is moved on X axis from one end to the other, the X values will change from 0 to and similar thing happens when moved along the Y axis.

When the joystick stays in its center position the value is around The graphic below shows the X and Y directions and also gives an indication of how the outputs will respond when the joystick is pushed in various directions.

In order to put this thumb joystick to use, you are going to want to understand which direction is X and which direction is Y. You will also need to decipher the direction it is being pushed in either the X or the Y direction.

VCC supplies power for the module. You can connect it to 5V output from your Arduino. VRx gives readout of the joystick in the horizontal direction X-coordinate i. VRy gives readout of the joystick in the vertical direction Y-coordinate i. SW is the output from the pushbutton. As we know, in order to determine the X and Y coordinates of the joystick, we need to connect both analog outputs from the joystick to analog pins on the Arduino.

To read whether the joystick knob has been pressed down, we connect the SW pin of the joystick to digital pin D8 of the Arduino. Other than this, the joystick just simply needs power. The program is very simple. We will read the measurement from two analog inputs and one digital input.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have a Bluetooth LE Joystick with a couple of buttons.

esp32 hid joystick

I want to connect it directly to the app without using the Bluetooth Settings, but by connecting to it via BluetoothLeScanner. My understanding of this HID device may be erroneous. How can I find out which button got pressed, what position the joystick has been moved to? I guess that this has to occur via notifications to which I have to subscribe to. Is there any Android library avaliable to handle HID input devices?

What I do NOT want to do is to use the Bluetooth settings and connect to the device and have it become detected as a HID device and replace the keyboard with some odd mapping. I can connect to the device with my app, enumerate the services and characteristics. But from there on, I have no clue how to work with HID. Learn more. Asked 2 years, 5 months ago.

I couldn't find any information on this. Daniel F Daniel F For what it's worth, a friend had a stroke and is now mostly unable to talk. Would be open sourced. Upon connecting I do "subscribe" to the notifications of the Report Characteristic in the onServicesDiscovered. But I never receive anything else from the device, onCharacteristicChanged is not called upon a button press. I'm reading through github. Maybe I need to bind to it somehow.

You maybe should do a GATT server connection? Maybe the next answer should help you a bite: stackoverflow. Active Oldest Votes. Sign up or log in Sign up using Google.Instead buying one, why not build my version?

Like Like. I have opened Joystick example from GitHub. It is setup in Processor Express for dual axis joystick. I need to extend for four axis and use more switches. How to do it? Hi Marceli, to add more push buttons, simply indrease the number in the component. For the multiple axis, you have to go into the USB code and extend it. Best if you could then extend the component code and contribute it back?

It seems is simple to extend the code making new selectable methods for three and four axis by PE. What CodeWarrior environment I need use to make it very fast. Regards, Marceli. Do you really need CodeWarrior? Not sure what is wrong on your side. I would first start with a project without any ethernet support. Is this tutorial with KDS or with codewarrior? Because here it looks like codewarrior but on github the folder the project is in is KDS. It is for KDS.

But it works the same way with minor changes project creation for CodeWarrior too. I have sent you as well the updated component by email to your Yahoo email address.

I hope this fixes the problem, and thank you so much for reporting it! Hi Erich, Thank yo very much for sharing, can this joystick do the calibration in Windows like the commercial one does?

Skip to content. There are examples for Keyboards and Mice out there, however I can't seem to get a Gamepad-Demo working, especially since the Documentation on this is so sparse. Its very easy to build gamepad with just as little code changes. Its enough to change reportMap, add interrupts for buttons and build proper structure according to reportMap. The base of a code came from a keyboard example, i've changed the HID descriptor and some other thingbut i dont know the way how to send the controller data back to PC.

I had a previous try with arduino, but the esp32 bluetooth functionality fits more to my expectation. On the arduino version i just had to write the data structure to the serial port, but im not sure here how i can send it. If you are using UNO, don't need to change this value.

Out of the box the Arduino Leonardo and the Arduino Micro appear to the host computer as a generic keyboard and mouse. This article discusses how the Arduino Leonardo and the Arduino Micro can also appear as one or more generic Game Controllers or Joysticks. The Arduino Joystick Library Version 2.

This will not work with Arduino IDE 1. The latest build of Version 2. On Microsoft Windows machines this can be done by executing deploy. The library should now appear in the Arduino IDE list of libraries. The example Arduino sketch files listed below are included in this library. JoystickTest — Simple test of the Joystick library.

MultipleJoystickTest - Creates 4 Joysticks using the library and exercises the first 16 buttons, the X axis, and the Y axis of each joystick when pin A0 is grounded.

esp32 hid joystick

JoystickButton - Creates a Joystick and maps pin 9 to button 0 of the joystick, pin 10 to button 1, pin 11 to button 2, and pin 12 to button 3. JoystickKeyboard - Creates a Joystick and a Keyboard. HatSwitchTest - Creates a joystick with two hat switches. Grounding pins 4 - 11 cause the hat switches to change position. The JoystickTest example sketch is included with the library.

I recommend using this example to verify everything is working properly before beginning to write your own sketch files.

Once you have uploaded the JoystickTest sketch file to the Arduino Leonardo or Micro, perform the following steps to verify everything is working properly. Note: the following steps are for Windows If you have a different version of Windows or a different operating system, these steps may differ.

The Arduino Leonardo or Micro should appear in the list of installed game controllers. Select the Arduino Leonardo or Micro and click the Properties button to display the game controller test dialog. Once the Arduino Leonardo or Micro has been tested using the JoystickTest example, I suggest making a simple gamepad controller. You will need five buttons to build this simple example.

Each button will correspond to one of the following joystick functions: up, down, left, right, and fire. Connect one end of each button to the ground pin of the Arduino.

Connect the other end of each button as indicated below:. This example is included with the Arduino Joystick Library. Open the game controller properties or use the joystick testing application of your choice to test the behavior of your gamepad.

More information about the Arduino Joystick Library Version 2. Question 2 months ago on Introduction. My specific box has 4 rotary encoders and an additional 21 buttons.
