Figure 4-10: Transmit Windowpane
When you run CalibrateCompass.bs2, you will first be prompted to click the Debug
Terminal's Transmit windowpane (shown in Figure 4-10), and then to press Enter. After
that you will be prompted to type C for calibrate or R for review calibration settings.
Typing the letter C will start the calibration, during which you will be prompted to point
the compass to 0°, and 90° as shown in Figure 4-9, and then to: 180°, 270°, 0°, 22.5°,
45°, 67.5°, 90°, 112.5°, 135°, 157.5°, 180°, 202.5°, 225°, 247.5°, 250°, 292.5°, 315°, and
finally, 337.5°. You will need to press the Enter key before advancing your board to each
angle.

Open and run CalibrateCompass.bs2.
Follow the prompts until you get to the "CALIBRATION COMPLETED"
message.
If you make a mistake, restart the program and start from the beginning. The
calibration process only takes a minute or two, and it's worth it to have the
correct settings in your BASIC Stamp 2's EEPROM memory.
