AKM Sensor Control Program support two types of evaluation boards that can be used for developing software of AKM electronic compass are available.
Sensor daughter board
AKM electronic compass and 3-axis acceleration sensor mounted board can be provided.
16 × 20 mm
AKM sensor evaluation board for Arduino
Board that connects above Sensor daughter board to the MCU board with Arduino Uno equivalent connector.
* These evaluation boards will be charged. For details, please contact our sales representative or agency.
* Please prepare the MCU board by customer.
When you are using compass application on a mobile terminal (such as a smartphone), have you ever seen the message such as "Interference from a magnetic field. Re-calibrate by waving the phone in a figure 8 motion"? This message is displayed when the phone moves into a magnetic field, and the electronic compass suffers interference from the field. When this occurs, the electronic compass can't detect the azimuth direction at a high accuracy without a re-calibration.
We don't neet to manually re-calibrate, because the AKM electronic compass has an auto-calibration routine by software. However, the method of "waving the cell phone in a figure 8 motion" is quick and effective method to re-calibration. But, you don't know how to move the phone in "a figure 8 motion", don't you ? So, we have created a web-site that explains in detail how to calibrate the electronic compass.
You can easily learn about how to calibrate while watching the video in this web-site.
Come web-site to see it.
