Flash board with calibration.ino
Connect a host via I2C (see provided host-example.ino)
Insert each calibration drill bit shafts and replace the lookup table entries in driver.ino with your own measurements
- Measure the actual diameter of the shafts and fill second column
- Use the host's output multiplied by 1000 to fill first column
Finally, flash driver.ino with your values filled out
Hub should now output exact diameter values
Note: Analog output is currently not enabled in driver.ino (I2C and FAULT pin only)
