Gyro 7 Click

How does it work?

Gyro 7 Click as its foundation uses the ICG-1020S, a high-performance 2-axis gyroscope from TDK InvenSense. The ICG-1020S is highly configurable with a full-scale programmable range from ±46.5dps to ±374dps. The single structure vibratory MEMS rate gyroscope detects the X- and Y-axis rotation. When the gyroscope is rotated about any sense axes, the Coriolis effect causes a detected vibration. The resulting signal is amplified, demodulated, and filtered to produce a proportional voltage to the angular rate. With its 2-axis integration, this Click board™ allows customers’ to design it into an optical image stabilization (OIS) application.

Two-axis MEMS rate gyroscope sensor, the ICG-1020S, comes with integrated 16-bit ADCs and signal conditioning with two axes XY configuration. After the signal is digitized, data is processed through a digital filter and output through sensor data registers. Besides, the ICG-1020S is also characterized by high resolution and low RMS noise, noise density, a fast sample rate at up to 32kHz, and low power consumption.

Gyro 7 Click communicates with MCU through a register-selectable standard SPI interface that enables high clock speed up to 20MHz, supporting the two most common SPI modes, SPI Mode 0 and 3. Other blocks include onboard clocking, temperature compensation, and bias circuits. The sensor data registers contain the latest gyro data, and they are read-only registers accessible via the serial interface. Data from these registers may be read anytime. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labeled as INT, indicating when a specific interrupt event occurs.

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. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Software Support

We provide a library for the Gyro 7 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Gyro 7 Click driver.

Key functions

• gyro7_get_int_pin This function returns the INT pin logic state.

• gyro7_read_gyroscope This function reads the gyroscope X and Y axis in degrees per second (dps).

• gyro7_read_temperature This function reads the internal temperature in Celsius.

Example Description

This example demonstrates the use of Gyro 7 Click board™ by reading and displaying the values of X and Y axis in degrees per second and the chip internal temperature in Celsius.

void application_task ( void ) 
 { 
     if ( gyro7_get_int_pin ( &gyro7 ) ) 
     { 
         float x_axis, y_axis, temperature; 
         if ( GYRO7_OK == gyro7_read_gyroscope ( &gyro7, &x_axis, &y_axis ) ) 
         { 
             log_printf( &logger, " X : %.2f dpsrn", x_axis ); 
             log_printf( &logger, " Y : %.2f dpsrn", y_axis ); 
         } 
         if ( GYRO7_OK == gyro7_read_temperature ( &gyro7, &temperature ) ) 
         { 
             log_printf( &logger, " Temperature : %.2f Crnn", temperature ); 
         } 
     } 
 }

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Gyro7

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.

mikroSDK

This Click board™ is supported with mikroSDK – MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
