KXCJK1013 Class Reference

KXCJK1013 Tri-axis Digital Accelerometer API. More...

Detailed Description

• ID: kxcjk1013
• Name: KXCJK1013 Tri-axis Digital Accelerometer
• Category: accelerometer
• Manufacturer: Kionix
• Connection: iio i2c

The KXCJK is a tri-axis +/-2g, +/-4g or +/-8g silicon micromachined accelerometer.

    // Instantiate a KXCJK1013 Accelerometer Sensor on iio device 0
    accelerometer = new upm::KXCJK1013(0);
    accelerometer->setScale(0.019163);
    accelerometer->setSamplingFrequency(25.0);
    accelerometer->enable3AxisChannel();
    accelerometer->installISR(data_callback, NULL);
    accelerometer->enableBuffer(16);

    while (shouldRun) {
        sleep(1);
    }
    accelerometer->disableBuffer();

void installISR	(	void(*)(char *)	isr,
		void *	arg
	)

Installs an interrupt service routine (ISR) to be called when an interrupt occurs

Parameters

interrupt	channel
fptr	Pointer to a function to be called on interrupt
arg	Pointer to an object to be supplied as an argument to the ISR.

int64_t getChannelValue	(	unsigned char *	input,
		mraa_iio_channel *	chan
	)

Extract the channel value based on channel type

Parameters

input	Channel data
chan	MRAA iio-layer channel info
