Assembly and setup¶
Calibration¶
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)
