An open-source Game Controller App that allows you to use an Xbox/Ps4/Joycon or any controller that works with your phone to effortlessly control most micro-controllers such as Arduino/Esp8266/Raspberry Pi over WiFi, bluetooth, or USB. I have also made a Car controllered by this app.
This new video below demonstrates and explains how it works:
Sorry it took a few days to upload all this stuff to github. Apparently, TCP protocol is pretty bad for streaming, so I decided to use UDP.
I'm just learning this stuff straight out of college so..yeah. Also, regarding respect to co-workers, I realized using Linus Torvalds as a role model sounds kind of bad. XD
-Thanks, Nathan Ramanathan
College DOES NOT TEACH YOU, only StackOverflow, Google, other people's code-on-Github are your teachers
Works with any controller that can connect to your phone. They are called HID/Bluetooth controller devices.
Note: For Wii U/Switch, you must use the Mayflash Adapter(Because Nintendo hates open-source)
Yes, please contribute. It will make the community a much better and active environment. Also, running away with the source code without recognizing us and knowing how it works it just plain rude. :\
Yes, it will be there once I add "Terminal mode" and "Phone as a Gamepad" mode. Also, Google Play has been removing more and more apps lately, so I'm worried that my app may be removed. But at least it's open-source :)
The Phone is the most powerful device that we all carry in our pockets, It can perform stuff on its screen while doing some magic in the background. So how does it work? It's quite simple, really :D
For my app, the game controller connects via bluetooth or USB to your phone.
The Android IDE(aka Android Studio) has built-in functions to handle keyEvents like a button press or joystick movement. It can even detect keyboard presses and mouse clicks.
Well, my app takes these controller inputs and sends them to the ESP8266 (aka best WiFi microcontroller) by the network SSID: "ESPTest". The way I programmed the Esp8266 is based on my MusicWithoutDelay library. This means we will use the Char-by-Char or Streaming method to evaluate each byte in the order it came. For example, the phone sends a UDP packet containing two values that I made up. So, if I press the
Abutton on my Xbox controller, my phone will send
a1to the esp8266. So
a1means the A button was pressed, and
a0vias versa. I'm pretty sure this techinque is used a lot in the industries.
The Esp8266 acts as the server, while my phone is the client. Fortunately, you don't have to connect to this server manually. My app immediately starts searching for WiFi devices with the name "ESPTest" within your area. I tried to mimic Google Chromecast's method, but its hard to decipher :/
Next, after the phone connects to your esp8266, it will enable streaming mode. This mode allows you to send UDP packets to your esp8266 quickly. Of course, there are many problems that arose. Because UDP is so fast, it caused my esp8266 to Crash XD.
The solution I found was to pause the UDP stream if the game controller sent the same stuff before. Essentially, I'm muting extra repeating data. This idea/method is very similar with my SensorToButton library. You can check that out, as it's very simple to use.
The only downside is that some packets can be lost, but since this is game data, we don't care because the Human button press only takes around 10-20 ms which is hardly noticeable when streaming :) But you could try and clicking faster and see a few hiccups, but let's just be honest that this looks cool; it's just so satisfying to see an LED fade when its being controlled by a Xbox controller's joystick.
Submit an Issue and we'll fix it. :)
Things I plan to do: - [x] ~~Fix Esp8266 from WDT resets, which is caused by doing an action too fast(such as printing to Serial or analogWrite())~~ - [x] ~~Create a Table of Contents~~ :D - [ ] Create TinkerController Arduino Library - [x] ~~Add WiFi support~~ - [ ] Add Bluetooth support(If its fast enough to handle gamecontroller input) - [ ] Add USB support - [ ] Allow a Keyboard/Mouse to act as a game controller - [ ] Add MQTT/CloudMQTT support (This allows playing over the internet anywhere in the world for free) - [ ] Make the Phone act as the server instead of the Esp8266 + This will allow us to connect as many WiFi devices to the phone + You can add multiple controllers to the Phone thus creating a game server :D - [ ] Create a page to access and change Esp8266 password and other stuff + Essentially, I'm trying to mimic Google Chromecast's Setup procedure - [ ] Make a Terminal for communicating via TCP/UDP. - [ ] Make the Phone as a Gamepad, because some people don't have controllers - [ ] Conquer my fear: Dagger 2 :'( - [x] Have Fun :D
I decided to use UDP because it's WAYYYYYYY faster than TCP. I didn't know if esp8266 had a UDP library, but low and behold it did :)
