| ADC | Diameter | Remove |

We use above calibration points to estimate filament diameter using linear interpolation.
First and last point are boundary items and can not be removed.
The firmware has been compiled to allow up to $MAX_CALIBRATION_POINTS$ calibration points.
Calibration procedure (using drill bit)
1. Measure drill bit using calipers and note the diameter size in mm
2. Insert the drill bit into WInFiDEL sensor and note the ADC value
3. In the input box below enter the measured diameter from step #1
4. Click on `Calibrate` button and wait for page to reload.
5. Verify that the list of calibration points has been updated.
Current ADC value of
should be calibrated as
Note: Update existing calibration point by specifying same `mm` diameter.
Note: If new point has same ADC or mm value as the existing one. Existing point will be updated.
| Parameter | Value | Note |
|---|---|---|
| MAX_CALIBRATION_POINTS | $MAX_CALIBRATION_POINTS$ | Maximum number of calibration points supported by firmware. |
| CALIBRATION_POINT_SAMPLE_COUNT | $CALIBRATION_POINT_SAMPLE_COUNT$ | Number of ADC samples taken when creating a calibration point |
| CALIBRATION_POINT_ACCURACY_POINT | $CALIBRATION_POINT_ACCURACY_POINT$ | When creating calibration point. All ADC samples must be within `$CALIBRATION_POINT_ACCURACY_POINT$` points of each other. Otherwise we will fail to create a calibration point due to ADC noise. |
| ADC_MIN | $ADC_MIN$ | Minimum value ADC can provide |
| ADC_MIN_EQUALS_MM | $ADC_MIN_EQUALS_MM$ | Minimum ADC value is treated as `$ADC_MIN_EQUALS_MM$`mm |
| ADC_MAX | $ADC_MAX$ | Maximum value ADC can provide |
| ADC_MAX_EQUALS_MM | $ADC_MAX_EQUALS_MM$ | Maximum ADC value is treated as `$ADC_MAX_EQUALS_MM$`mm |
| BUILD_TIME | $BUILD_TIME$ | Time when firmware was compiled |
| BUILD_DATE | $BUILD_DATE$ | Date when firmware was compiled |
| ADC_ALGO | $ADC_ALGO$ | Which alghoritm is used to calculate final ADC value |
| ADC_CHIP | $ADC_CHIP$ | Which ADC chip is populated on the board |
Values in this table are provided for development/debugging purposes (and just for fun).
You should not have to worry about them during devices normal operation.
