Please note the USB port can only supply a limited amount of power to the keyboard (500mA by standard, however, modern computer and most usb hubs can provide 700+mA.). According to the data of NeoPixel from Adafruit, 30 WS2812 LEDs require a 5V 1A power supply, LEDs used in this mod should not more than 20.

## PS/2 Mouse Support
|
||||
|
||||
Its possible to hook up a PS/2 mouse (for example touchpads or trackpoints) to your keyboard as a composite device.
|
||||
In order to do this you must first enable the option in your Makefile.
|
||||
|
||||
PS2_MOUSE_ENABLE = yes
|
||||
|
||||
Then, decide whether to use interrupts (better if your microcontroller supports them) or busywait, and enable the relevant option.
|
||||
|
||||
PS2_USE_INT = yes
|
||||
// PS2_USE_BUSYWAIT = yes
|
||||
|
||||
If you're using a teensy and have hooked up the clock on your PS/2 device to D1 and the data to D0, you're all set.
|
||||
Otherwise, you will need to update the following defines in your `config.h`:
|
||||
|
||||
#define PS2_CLOCK_PORT PORTD
|
||||
#define PS2_CLOCK_PIN PIND
|
||||
#define PS2_CLOCK_DDR DDRD
|
||||
#define PS2_CLOCK_BIT 1
|
||||
|
||||
#define PS2_DATA_PORT PORTD
|
||||
#define PS2_DATA_PIN PIND
|
||||
#define PS2_DATA_DDR DDRD
|
||||
#define PS2_DATA_BIT 0
|
||||
|
||||
And with `PS2_USE_INT` also define these macros:
|
||||
|
||||
#define PS2_INT_INIT() do { \
|
||||
EICRA |= ((1<<ISC11) | \
|
||||
(0<<ISC10)); \
|
||||
} while (0)
|
||||
#define PS2_INT_ON() do { \
|
||||
EIMSK |= (1<<INT1); \
|
||||
} while (0)
|
||||
#define PS2_INT_OFF() do { \
|
||||
EIMSK &= ~(1<<INT1); \
|
||||
} while (0)
|
||||
#define PS2_INT_VECT INT1_vect
|
||||
|
||||
## Safety Considerations
|
||||
|
||||
You probably don't want to "brick" your keyboard, making it impossible
