- MI = MISO
- MO = MOSI
- SS = Slave Select / Chip Select
- SC = SPI Clock
- MT = Motion (active low interrupt line)
- RS = Reset
- GD = Ground
- VI = Voltage in up to +5.5V (will work with 3.3v)
- PMW3389DM-Mouse/
- Mouse with high polling rate and 4 main buttons: Left, Right, Middle, Back, plus 2 user-definable Keyboard buttons
- Default CPI and debounce time can be set (see #define sections in the source code)
- Cycle through CPI with button combo (back + right click), LED will update to show which mode is selected
- Check the 3D_models folder
- Build the circuit as described.
- (Arduino only) Copy the /library/AdvMouse/ to your Arduino library folder
- Load PMW3389DM-Mouse on Arduino IDE.
- Change dx, dy to positive values if input is reversed
- Upload code to Arduino
- Enjoy!
