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.

vdd-supply:

|
description: An optional regulator providing core power supply
|
|
on the VDD pin, typically 1.8 V or 3.0 V.

iovdd-supply:
|
|
description: An optional regulator providing I/O power supply
|
|
for the I2C interface on the IOVDD pin, typically 1.8 V.
