+# PICO-GAMEPAD-CONVERTER
+
+[![ko-fi](https://ko-fi.com/img/githubbutton_sm.svg)](https://ko-fi.com/O4O8TQSC8)
+
+PicoGamepadCoverter is a project designed for RP2040 or Raspberry Pi Pico and variants, that enabling switch to different gamepad modes using a gamepad as input. Re-use old gamepads that dont't support USB conecctions or make compatibles with certain platafform.
+
+---
+## Features
+
+- Read input from USB and Bluetooth controllers.
+- Read inputs from no USB peripherals.
+- Web interface to choose between modes.
+- Different out modes (Dinput, Xinput, Switch, Bluetooth)
+- Easy to use, no overcomplicated options.
+
+---
+## Getting Started
+
+To get started with PicoGamepadConverter, follow the steps below:
+
+### Prerequisites
+
+- Raspberry Pi Pico microcontroller or onother RP2040 boards.
+- OTG cable (micro-USB or USB-C it depents on your board)
+- USB female connector (Recommended be the same type of OTG cable)
+- USB cable (micro-USB or USB-C it depents on your board)
+- Two push buttons (_Optional but RECOMMENDED!_)
+- Breadboard (_Optional_)
+
+### Installation
+
+1. Download the build program and copy on the microcontroller.
+
+   ```
+   git clone https://github.com/Loc15/PicoGamepadConverter.git
+   ```
+
+2. Make the conections.
+
+![schematic](./docs/pico_pinout.png)
+![conections1](./docs/bread_board1.jpg)
+![conections2](./docs/bread_board2.jpg)
+
+3. Go to configuration mode pressing the button on 18 GPIO on start. On web mode the led start to blink.
+
+4. Choose the modes on the web server. Access http://192.168.3.1 in a web browser to begin configuration.
+
+![web_mode](./docs/web_configurator.png)
+
+5. Connect your gamepad, when it connected successfully the led on the board gonna turn on.
+
+6. Enjoy!
+
+
+### Additional information
+
+- The led on board indicates that a gamepad has been mounted successfully, it works on all host modes except **Keyboard PS/2**
+
+- The additional USB female connector PINS are **16** and **17 GPIO**.  
+
+- The conection for Keyboard PS/2 are on **19 GPIO** for **DATA PIN** and **20 GPIO** for **CLOCK PIN**.
+
+![keyboard_schematic](./docs/keyboard_pinout.png)
+![keyboard_connector](./docs/keyboard_connector.jpg)
+![keyboard_pc](./docs/keyboard_pc.jpg)
+
+- The conection for PS1 controllers are on **19 GPIO** for **COMMAND PIN**, **20 GPIO** for **CLOCK PIN**, **21 GPIO** for **ATTENTION PIN** and **22 GPIO** for **DATA PIN**
+
+![ps1_schematic](./docs/ps1_pinout.png)
+![ps1_connector](./docs/ps1_connector.jpg)
+![ps1_pc](./docs/ps1_pc.jpg)
+
+- Bluetooth modes only works on Pico W.
+
+- On Bluetooth device mode, the host connection is on **native usb female connector on the microcontroller**.
+
+- On Bluetooth host mode you must put the mac adress of your gamepad. You can get this adress connecting you gamepad to a PC or a mobile phone. This adress _should_ be put just once time, next time you just need choose the mode.
+
+---
+## Modes
+Exist two parameter to choose on web interface, **host** and **device**. The first is the input and another one the output.
+
+### HOST
+#### USB MODES
+- Xinput: Support Xbox controllers or Xinput compatibles controllers.
+- Dinput: Support generic gamepads, PS4, PS3 and 8BITDO controllers.
+
+#### Wireless MODES
+- Bluetooth: Support generic gamepads, PS4 and 8BITDO controllers.
+
+#### SPECIAL MODES
+- Keyboard/PS2: Support keyboards with PS/2 connector.
+- PS1/PS2: Support PS1 controllers (For now PS2 controller doesn't work well)
+
+ ### DEVICE
+ #### USB MODES
+ - Xinput: Simulation of Xinput gamepad controllers (doesn't work on consoles, only on PC).
+- Dinput: Simulation of a generic HID gamepad.
+- Switch: Simulation of Switch Pro controller.
+
+#### Wireless MODES
+- Bluetooth: Simulation of a generic HID gamepad.
+
+---
+## Features
+
+You can to set some additional configuration if you required:
+
+![features](./docs/features.png)
+
+- Block analogs.
+- Swap Dpap and Left analog.
+- Add deadzone to analogs.
+
+---
+
+## Testing
+Controllers that was tested on diferent host modes.
+
+| Tested Controllers     | 	Modes (Host) |
+| ------------------     | -------------- |
+| Logitech F710          | Xinput, Dinput |
+| 8BitDo Ultimate 2.4G   | Xinput, Dinput, Bluetooth|
+| 8BitDo Ultimate C 2.4G | **Doesn't work** |
+| DualShock (PS1)        | PS1/PS2          |
+| DualShock 2 (PS2)      | _Works weird_    |
+| DualShock 3 (PS3)      | Dinput |
+| DualShock 4 (PS4)      | Dinput, Bluetooth|
+| Keyboard HP KB-0316    | Keyboard PS/2    |
+
+---
+
+### Troubleshooting
+
+- 8bitdo controllers sometimes have problems to connect on USB or Bluetooth mode. On USB if it doesn't connect reboot the microcontroller without disconnect. 
+
+- On Bluetooth if doesn't connect on first, reboot and put your gamepad on pair mode.

+
+**Expected behavior**
+
+A clear and concise description of what you expected to happen.
+
+**HCI Packet Logs**
+For all Bluetooth issues, please provide a full packet log that includes initial pairing. You need to zip the packet log as GitHub does not know how to handle .pklg files. 
+
+How to get packet log depends on the port:
+- For desktop ports, full packet logging is enabled by default and the packet log is available as `/tmp/hci_dump.pklg` (Mac/Linux), or `hci_dump.pklg' (Windows).
+- For embedded ports, you can enable #define ENABLE_LOG_INFO in btstack_config.h and uncomment the call to 'hci_dump_init(..)' in the main() function to enable logging over UART Console or Segger RTT. Please capture text output and process using `btstack/tool/create_packet_log.py`. The tool will generate the text file into a .pklg file which can be analysed with Wireshark or Apple's PacketLogger tool.
+- For ESP32: BTstack's `port/esp32/integrate.py` script creates one project per example. To enable packet logging, you need to edit app_main in main/main.c of the example project.
+
+**Environment:  (please complete the following information):**
+ - Current BTstack branch: [e.g. develop]
+ - Bluetooth Controller [e.g. CSR 8510, TI CC2564C, ...]
+ - Remote device: [e.g. iPhone X with iOS 13.3]
