Attributes

NameTypeRequired?Description
boardstringRequiredThe name of the board to which the device is wired.
i2c_busstringRequiredThe name of the I2C bus on the board wired to this device.
use_alt_i2c_addressboolOptionalDepends on whether you wire SDO low (leaving the default address of 0x53) or high (making the address 0x1D). If high, set true. If low, set false or omit the attribute.
Default: false
