ADXL362DMA
Library for ADXL362 accelerometer that uses SPI DMA for efficient transfers
The ADXL362 is an inexpensive 3-DOF ultra-low power accelerometer. It can do movement detection from rest continuously at 270 nA (yes, nano-amps!) and also has a large FIFO that makes it possible to buffer samples while the processor is busy or even sleeping.
The GY362 is a compatible version of the ADXL362 and also works with this library.

Software
Instantiate a global object for the accelerometer. The first parameter is the SPI bus amd the second is the CS line.
ADXL362DMA accel(SPI, A2);
Initialize the chip:
accel.softReset();
while(accel.readStatus() == 0) {
Log.info("no status yet, waiting for accelerometer");
delay(1000);
}
Enable measuring mode (it boots into standby mode):
accel.setMeasureMode(true);
}
Read data. There is also a function to read roll and pitch data instead of raw data, see example 4-rollpitch.
int16_t x, y, z;
accel.readXYZ(x, y, z);
Serial.printlnf("%5d %5d %5d", (int)x, (int)y, (int)z);
