About

This is a manual test application for the InvenSense ITG320X 3-axis gyroscope driver.

Usage

The test application demonstrates the use of the ITG320X. It uses the default configuration parameters:

  • Low pass filter bandwidth (LPF_BW) of 5 Hz (ITG320X_LPF_BW_5)
  • Internal sample rate (ISR) of 1 kHz which results from LPF_BW of 5 Hz
  • Internal sample rate divider (ISR_DIV) of 99 (ITG320X_PARAM_ISR_DIV)
  • Output data rate (ODR) of 10 Hz resulting from ODR = ISR / (ISR_DIV + 1)

The application may use two different approaches to retrieve new data, either

  • periodically fetching the data at a rate lower than the sensor's output data rate (ODR), or
  • fetching the data when the data-ready interrupt is triggered.

To use the latter approach, module itg320x_int has to be enabled and the GPIO to which the sensor's INT output pin is connected has to be defined by #ITG320X_PARAM_INT_PIN, for example:

USEMODULE=itg320x_int CFLAGS="-DITG320X_PARAM_INT_PIN=\(GPIO_PIN\(0,3\)\)" \
