Hello,

Here is my little contribution on how to connect a Spintrak to the Teensy enabling a HID mouse.

I'm using the Mouse and Encoder library. Big thanks to the author(s).

This is for 1 spinner on the x axis, but you can add a second one on the y axis.

Here is the source code I'm using:

Code:
#define ENCODER_OPTIMIZE_INTERRUPTS
#include <Encoder.h>

Encoder spinner_x(2, 3);
int x, prev_x = 0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int diff_x;
  x = spinner_x.read();
  diff_x = x - prev_x;
  Serial.print("Spinner 1 = ");
  Serial.print(diff_x);
  Serial.println();
  Mouse.move(diff_x, 0);
  prev_x = x;
}

Also, if you want a Mouse Only profile you can take a look at this thread:

Pitou!
