====== Raspberry Pi NAS: Gamepad as Kodi remote ======

I have two SNES-Like gamepads, both are recognized by the Linux kernel Dragonrise module **hid_dr**. The older one is shipped with bot an **USB dongle** and a **Nintendo adapter**, the second one **has only the USB dongle**. In the picture the USB only model is the one with **colored keys**:

{{.:raspberrypi:gamepad-dragonrise-0079-0011.jpg?280|}}
{{.:raspberrypi:gamepad-dragonrise-0079-0126.jpg?280|}}

They are different models: the old model is identified by **lsusb** with this output line:

<code>
Bus 001 Device 010: ID 0079:0011 DragonRise Inc. Gamepad
</code>

The new model has a different ID:

<code>
Bus 002 Device 004: ID 0079:0126 DragonRise Inc.
</code>

To **pair** the gamepad with the USB receiver, first proceed by disconnecting the host USB dongle. Press the **Start**, **Select** and **Up** buttons simultaneously on the gamepad; the red LED starts flashing rapidly. During the next 10 seconds you have to insert the USB receiver into the host port, the pairing takes place automatically. 

===== Configuring the gamepad in Kodi =====

You have to install the package 

  * **kodi-peripheral-joystick**

Other packages may be useful to debug and solve problems:

  * **input-utils** - Contains the **lsinput** and **input-events** tools, used to view input events produced by the gamepad.
  * **evtest** - Contains the **evtest** tool, used to monitor input events.

Install the **kodi-peripheral-joystick** package and restart **Kodi**, then go to **Settings** => **System settings** => **Input** => **Configure attached controller**. In this section you can choose the controller type: Kodi 17.6 has only the **generic** one, Kodi 18.7 has a **generic Kodi** and a specific **Super Nintento**.

Il is possible to configure each key, but default settings should be OK.

Custom configuration is saved into the directory **$HOME/.kodi/userdata/peripheral_data/**, in our case the file was named **addon_YSTEK_MICREAL_USB_Gamepad.xml**.

The gamepad goes to stand-by after some time of non-use. To wake it up it is necessary to press the **start** button; the red LED turns on and the gamepad is working.

===== Problem: non working left and right arrows =====

Everything is working correctly with a **Raspberry Pi 3**, using RaspiOS based on **Debian 9.11 Stretch** and **Kodi 17.6**. There is instead a problem with a **Raspberry Pi 4**, using RaspiOS based on **Debian 10.8** and **Kodi 18.7**: the **Left** and **Right** arrow keys do not work.

Someone had the same problem using Retropie: **[[https://retropie.org.uk/forum/topic/25657/controler-issue-no-left-and-right-not-working-at-all/| Controler Issue (no left and right not working at all)]]**.
