# Joystick :id=joystick
Hid joystick interface (#4226) * add support for hid gamepad interface add documentation for HID joystick Add joystick_task to read analog axes values even when no key is pressed or release. update doc Update docs/feature_joystick.md Manage pin setup and read to maintain matrix scan after analog read * Incorporates patches and changes to HID reporting There are some patches provided by @a-chol incorporated on this commit, and also some changes I made to the HID Report structure. The most interesting is the one dealing with number of buttons: Linux doesn't seem to care, but Windows requires the HID structure to be byte aligned (that's in the spec). So if one declares 8/16/32... buttons they should not have any issues, but this is what happens when you have 9 buttons: ``` bits |0|1|2|3|4|5|6|7| |*|*|*|*|*|*|*|*| axis 0 (report size 8) |*|*|*|*|*|*|*|*| ... |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| axis 6 |*|*|*|*|*|*|*|*| first 8 buttons (report size 1) |*| | | | | | | | last of 9 buttons, not aligned ``` So for that I added a conditonal that will add a number of reports with size 1 to make sure it aligns to the next multiple of 8. Those reports send dummy inputs that don't do anything aside from aligning the data. Tested on Linux, Windows 10 and Street Fighter (where the joystick is recognized as direct-input) * Add save and restore of each pin used in reading joystick (AVR). Allow output pin to be JS_VIRTUAL_AXIS if the axis is connected to Vcc instead of an output pin from the MCU. Fix joystick report id Fix broken v-usb hid joystick interface.

This feature provides game controller input as a joystick device supporting up to 6 axes and 32 buttons. Axes can be read either from an [ADC-capable input pin](adc_driver.md), or can be virtual, so that its value is provided by your code.

An analog device such as a [potentiometer](https://en.wikipedia.org/wiki/Potentiometer) found on an analog joystick's axes is based on a voltage divider, where adjusting the movable wiper controls the output voltage which can then be read by the microcontroller's ADC.

Add the following to your `rules.mk`:
```make
JOYSTICK_ENABLE = yes
```

By default the joystick driver is `analog`, but you can change this with:
```make
JOYSTICK_DRIVER = digital
```

For instance, the below example configures two axes. The X axis is read from the `A4` pin. With the default axis resolution of 8 bits, the range of values between 900 and 575 are scaled to -127 through 0, and values 575 to 285 are scaled to 0 through 127. The Y axis is configured as a virtual axis, and its value is not read from any pin. Instead, the user must update the axis value programmatically.

Axes can be configured using one of the following macros:
Hid joystick interface (#4226) * add support for hid gamepad interface add documentation for HID joystick Add joystick_task to read analog axes values even when no key is pressed or release. update doc Update docs/feature_joystick.md Manage pin setup and read to maintain matrix scan after analog read * Incorporates patches and changes to HID reporting There are some patches provided by @a-chol incorporated on this commit, and also some changes I made to the HID Report structure. The most interesting is the one dealing with number of buttons: Linux doesn't seem to care, but Windows requires the HID structure to be byte aligned (that's in the spec). So if one declares 8/16/32... buttons they should not have any issues, but this is what happens when you have 9 buttons: ``` bits |0|1|2|3|4|5|6|7| |*|*|*|*|*|*|*|*| axis 0 (report size 8) |*|*|*|*|*|*|*|*| ... |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| axis 6 |*|*|*|*|*|*|*|*| first 8 buttons (report size 1) |*| | | | | | | | last of 9 buttons, not aligned ``` So for that I added a conditonal that will add a number of reports with size 1 to make sure it aligns to the next multiple of 8.

* `JOYSTICK_AXIS_IN(input_pin, low, rest, high)`
The ADC samples the provided pin. `low`, `high` and `rest` correspond to the minimum, maximum, and resting (or centered) analog values of the axis, respectively.
* `JOYSTICK_AXIS_IN_OUT(input_pin, output_pin, low, rest, high)`
Same as `JOYSTICK_AXIS_IN()`, but the provided `output_pin` will be pulled high before `input_pin` is read.
* `JOYSTICK_AXIS_IN_OUT_GROUND(input_pin, output_pin, ground_pin, low, rest, high)`
Same as `JOYSTICK_AXIS_IN_OUT()`, but the provided `ground_pin` will be pulled low before reading from `input_pin`.
* `JOYSTICK_AXIS_VIRTUAL`
No ADC reading is performed. The value should be provided by user code.

So if one declares 8/16/32... buttons they should not have any issues, but this is what happens when you have 9 buttons: ``` bits |0|1|2|3|4|5|6|7| |*|*|*|*|*|*|*|*| axis 0 (report size 8) |*|*|*|*|*|*|*|*| ... |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| |*|*|*|*|*|*|*|*| axis 6 |*|*|*|*|*|*|*|*| first 8 buttons (report size 1) |*| | | | | | | | last of 9 buttons, not aligned ``` So for that I added a conditonal that will add a number of reports with size 1 to make sure it aligns to the next multiple of 8. Those reports send dummy inputs that don't do anything aside from aligning the data. Tested on Linux, Windows 10 and Street Fighter (where the joystick is recognized as direct-input) * Add save and restore of each pin used in reading joystick (AVR). Allow output pin to be JS_VIRTUAL_AXIS if the axis is connected to Vcc instead of an output pin from the MCU. Fix joystick report id Fix broken v-usb hid joystick interface.

Documentation fixes * Fix port addressing for joystick analog read * The other required set of changes As per the PR, the changes still holding it up. Add onekey for testing. Fix ARM builds.
