Ploopyco Mouse

Ploopyco Mouse

It's a DIY, QMK Powered Trackball!!!!

Everything works. However the scroll wheel has some issues and acts very odd.

Make example for this keyboard (after setting up your build environment):

make ploopyco/mouse:default:flash

To jump to the bootloader, hold down "Button 4" (immediate right of the Mouse)

See the build environment setup and the make instructions for more information. Brand new to QMK? Start with our Complete Newbs Guide.

Customzing 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 censor.

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 Mouse by calling pmw_set_cpi at any time. And tThe default can be changed by adding a define to the keymap's config.h file:

#define PMW_CPI 1600

Programming QMK-DFU onto the PloopyCo Mouse

If you would rather have DFU on this board, you can use the QMK-DFU bootloader on the device. To do so, you want to run:

make ploopyco/trackball:default:production

Once you have that, you'll need to ISP Flash the chip with the new bootloader hex file created (or the production hex), and set the fuses:

Fuse Setting
Low 0xDF
High 0xD8 or 0x98
Extended 0xCB

Original (Caterina) settings:

Fuse Setting
Low 0xFF
High 0xD8
Extended 0xFE
