* PMW33XX drivers overhaul This combines the PMW3389 and PM3360 drivers as they only differ in the firmware blobs and CPI get and set functions. The following changes have been made: * PMW3389 now gets the same multi-sensor feature that is already available on the PMW3360. * Introduced a shared pmw33xx_report_t struct is now directly readable via SPI transactions instead of individual byte-sized reads, saving multiple copies and bitshift operations. * pmw33(89/60)_get_report functions had unreachable branches in their motion detection logic these have been simplied as much as possible. * The fast firmware upload option has been removed as this becomes obsolete by the newly introduced polled waiting functions for ChibiOS polled waiting * PMW33(60/89)_SPI_LSBFIRST and PMW33(60/89)_SPI_MODE config options have been removed as they don't need to be configurable. * All PMW3389 and PMW3360 defines have been unified to a PMW33XX prefix to reduce code duplication and make the defines interchangeable * Adjust keyboards to PMW33XX naming scheme |

Ploopyco Trackball
It's a DIY, QMK Powered Trackball!!!!
- Keyboard Maintainer: PloopyCo, Drashna Jael're, Germ
- Hardware Supported: ATMega32u4 8MHz(3.3v)
- Hardware Availability: Store, GitHub
Make example for this keyboard (after setting up your build environment):
make ploopyco/trackball/rev1:default:flash
make ploopyco/trackball/rev1_005:default:flash
To jump to the bootloader, hold down "Button 4" (immediate right of the trackball)
See the build environment setup and the make instructions for more information. Brand new to QMK? Start with our Complete Newbs Guide.
Revisions
There are two main revisions for the PloopyCo Trackball, everything up to 1.004, and 1.005-1.006.
In the 1.005 revision, button for was changed from pin B5 to B6, and the debug LED pin was changed from F7 to B5.
The PCB should indicate which revision this is.
Customizing your PloopyCo Trackball
While the defaults are designed so that it can be plugged in and used right away, there are a number of things that you may want to change. Such as adding DPI control, or to use the ball to scroll while holding a button. To allow for this sort of control, there is a callback for both the scroll wheel and the mouse sensor.
The default behavior for this is:
void process_wheel_user(report_mouse_t* mouse_report, int16_t h, int16_t v) {
mouse_report->h = h;
mouse_report->v = v;
}
void process_mouse_user(report_mouse_t* mouse_report, int16_t x, int16_t y) {
mouse_report->x = x;
mouse_report->y = y;
}
This should allow you to more heavily customize the behavior.
Alternatively, the process_wheel and process_mouse functions can both be replaced too, to allow for even more functionality.
Additionally, you can change the DPI/CPI or speed of the trackball by calling pointing_device_set_cpi at any time. Additionally, there is a DPI_CONFIG macro that will cycle through an array of options for the DPI. This is set to 1200, 1600, and 2400, but can be changed. 1600 is also set to the default.
To configure/set your own array, there are two defines to use, PLOOPY_DPI_OPTIONS to set the array, and PLOOPY_DPI_DEFAULT.
#define PLOOPY_DPI_OPTIONS { 1200, 1600, 2400 }
#define PLOOPY_DPI_DEFAULT 1
The PLOOPY_DPI_OPTIONS array sets the values that you want to be able to cycle through, and the order they are in. The "default" define lets the firmware know which of these options is the default and should be loaded by default.
The DPI_CONFIG macro will cycle through the values in the array, each time you hit it. And it stores this value in persistent memory, so it will load it the next time the device powers up.
Drag Scroll
Drag Sroll is a custom keycode for the Ploopy devices that allow you to hold or tap a button and have the mouse movement translate into scrolling instead.
Nothing needs to be enabled to use this functionality. Just add the DRAG_SCROLL to your keymap.
Drag Scroll Configuration
#define PLOOPY_DRAGSCROLL_MOMENTARY- Makes the key into a momentary key, rather than a toggle.#define PLOOPY_DRAGSCROLL_MULTIPLIER 0.75- Sets the DPI multiplier to use when drag scroll is enabled.#define PLOOPY_DRAGSCROLL_FIXED- Normally, when activating Drag Scroll, it uses a fraction of the current DPI. You can define this to use a specific, set DPI rather than a fraction of the current DPI.#define PLOOPY_DRAGSCROLL_DPI 100- When the fixed DPI option is enabled, this sets the DPI to be used for Drag Scroll.
#define PLOOPY_DRAGSCROLL_INVERT- This reverses the direction that the scroll is performed.
