ISM6HG256X

Arduino library to support the ISM6HG256X.

API

This sensor uses I2C, SPI, or I3C to communicate. For I2C it is then required to create a TwoWire interface before accessing to the sensors:

TwoWire dev_i2c(I2C_SDA, I2C_SCL);  
dev_i2c.begin();

For SPI it is then required to create a SPI interface before accessing to the sensors:

SPIClass dev_spi(SPI_MOSI, SPI_MISO, SPI_SCK);  
dev_spi.begin();

An instance can be created and enabled when the I2C bus is used following the procedure below:

ISM6HG256XSensor sensor(&dev_i2c);
sensor.begin();
sensor.Enable_X();
sensor.Enable_G();

An instance can be created and enabled when the I3C bus is used with SETDASA:

ISM6HG256XSensor sensor(&I3C, ISM6HG256X_I3C_ADD_L);
I3C.begin(I3C_SDA, I3C_SCL, 1000000U);
I3C.resetDynamicAddresses();
I3C.assignDynamicAddress(sensor.getStaticAddress(), 0x30);
sensor.begin(0x30);
sensor.Enable_X();
sensor.Enable_G();

An instance can be created and enabled when the I3C bus is used with ENTDAA (dynamic address discovery):

ISM6HG256XSensor sensor(&I3C);
I3C.begin(I3C_SDA, I3C_SCL, 1000000U);
I3C.resetDynamicAddresses();
I3C.discover(devices, 8, &found);
// find dynAddr by matching ISM6HG256X_I3C_PID_L in discovered devices
sensor.begin(dynAddr);
I3C.setClock(12500000);
sensor.Enable_X();
sensor.Enable_G();

An instance can be created and enabled when the SPI bus is used following the procedure below:

ISM6HG256XSensor sensor(&dev_spi, CS_PIN);  
sensor.begin();
sensor.Enable_X();
sensor.Enable_G();

The access to the sensor values is done as explained below:

ISM6HG256X_Axes_t accel, angrate;
sensor.Get_X_Axes(accel);
sensor.Get_G_Axes(&angrate);
