KX023-1025-IMU

Arduino library for KX023-1025 https://datasheet.lcsc.com/szlcsc/ROHM-Semicon-KX023-1025_C236128.pdf

Simple implementation of the basic functions for reading accelerometer data.

Constructors

SPI

KX0231025Class(SPIClass& spi, int csPin);

I2C

KX0231025Class(TwoWire& wire, uint8_t slaveAddress);

I2C has not been verified and tested as of yet. Refer to documentation for the correct slave address

Functions

begin(), begin(int powerMode, int accelerationRange, int outputDataRate)

Configures the accelerometer and changes its mode to operational mode

400,800,1600Hz mode is not possible in LOWPOWER powerMode.
LOWPOWER mode will affect the accuracy
With higher range it will loose accuracy by a factor of 2 for each step. 2G highest accuracy, 8G lowest accuracy

return

0 = Could not initialize with current settings
1 = Success

end()

Sets the chip in standby mode

return

0 = Failed
1 = Success

int end();

readAcceleration(float& x, float& y, float& z);

reads the latest available values from the accelerometer

return

0 = Failed
1 = Success

virtual int readAcceleration(float& x, float& y, float& z); // Results are in G (earth gravity).
