|
The Yamaha YAS530 magnetometers is a line of 3-axis magnetometers |
|
first introduced by Yamaha in 2009 with the YAS530. They are successors |
|
of Yamaha's first magnetometer YAS529. Over the years this magnetometer |
|
has been miniaturized and appeared in a number of different variants. |

description: The YAS530 sensor has a RSTN pin used to reset |
|
the logic inside the sensor. This GPIO line should connect |
|
to that pin and be marked as GPIO_ACTIVE_LOW. |

description: Interrupt for INT pin for interrupt generation. |
|
The polarity, whether the interrupt is active on the rising |
|
or the falling edge, is software-configurable in the hardware. |

|
description: An optional regulator providing core power supply |

|
description: An optional regulator providing I/O power supply |
