Join For FreeFor many projects, it would be cool to build a custom USB joystick, either as a custom game controller for Windows or any USB host that can be used with a USB joystick. Instead of buying one, why not build my version? All I need is a USB-capable board, some kind of input (potentiometer, push buttons) and some software, and I have my USB joystick:

In this article, I’m using the NXP FRDM-KL25Z (ARM Cortex-M0+) with a joystick (e.g. from Dx.com) shield:

The USB HID Joystick class is very similar to the USB Keyboard one, so follow the “Using the FRDM-KL25Z as USB Keyboard” tutorial for the basic USB setup.
Select the HID Joystick Device:

Then configure the HID device settings, especially the CPU/device used:

The component offers methods to set buttons, throttle, hat position, and X/Y joystick position:

I have published, on GitHub, an example project which uses X/Y analog position, 4 hat switches, a throttle setting plus 3 push buttons:

The USB HID device shows up with two devices in the Windows device manager:

Inside the Windows Control Panel, there is a dialog to set up any USB game controller:
Setup USB Game Controller
That dialog shows the controls and is used to calibrate them:
Setup USB Game Controller
Building a DIY game controller is easy with the addition of the USB HID joystick component and software. With a USB capable device and a joystick shield, I’m able to create my gaming controller.
Happy gaming!
