HOW DOES IT WORK?
Gyro 9 Click is based on the A3G4250D, a MEMS motion sensor from STMicroelectronics. It includes a sensing element and an IC interface capable of providing the measured angular rate to the host MCU. The sensor has a full scale of ±245dps and can measure rates with a user-selectable bandwidth. The sensor also embeds a 32-slot, 16-bit data FIFO for each of the three output channels: yaw, pitch, and roll. This allows consistent power saving for the system, as the host MCU doesn't need to poll the data continuously. There is also a Bypass mode, which lets FIFO not operational and empty. The third mode is a Stream mode.
Gyro 9 Click can use both the 4-wire SPI serial interface and the I2C interface to communicate with the host MCU. The selection can be made over the COMM SEL. The SPI is selected by default and supports clock frequency up to 10MHz. The I2C interface supports frequencies up to 400KHz. The I2C address can be selected over the ADDR SEL jumper (0 set by default). The gyroscope can be reset over the RST pin. The INT pin is a programmable interrupt and can be used in a combination of events. The DR is a data-ready output that generates dedicated interrupts depending on FIFO or Stream mode statuses.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
