Gyro 7 Click is a compact add-on board that contains a high-performance gyroscope. This board features the ICG-1020S, a dual-axis MEMS angular rate sensor (gyroscope) from TDK InvenSense. The ICG-1020S provides extremely low RMS noise as well as noise density. The high-resolution gyroscope supports a full-scale programmable range of ±46.5dps to ±374dps, a fast sample rate at up to 32kHz, an SPI serial interface, and extremely low power consumption. This Click board™ is designed for optical image stabilization (OIS) applications.

Gyro 7 Click is a compact add-on board that contains a high-performance gyroscope. This board features the ICG-1020S, a dual-axis MEMS angular rate sensor (gyroscope) from TDK InvenSense. The ICG-1020S provides extremely low RMS noise as well as noise density.

This Click board™ is designed for optical image stabilization (OIS) applications.
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.
This library contains API for Gyro 7 Click driver.
gyro7_cfg_setup
Config Object Initialization function.
void gyro7_cfg_setup ( gyro7_cfg_t *cfg );
gyro7_init
Initialization function.
err_t gyro7_init ( gyro7_t *ctx, gyro7_cfg_t *cfg );
gyro7_default_cfg
Click Default Configuration function.
err_t gyro7_default_cfg ( gyro7_t *ctx );
gyro7_get_int_pin
This function returns the INT pin logic state.
uint8_t gyro7_get_int_pin ( gyro7_t *ctx );
gyro7_read_gyroscope
This function reads the gyroscope X and Y axis in degrees per second (dps).
err_t gyro7_read_gyroscope ( gyro7_t *ctx, float *x_axis, float *y_axis );
gyro7_read_temperature
This function reads the internal temperature in Celsius.
err_t gyro7_read_temperature ( gyro7_t *ctx, float *temperature );
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.
The demo application is composed of two sections :
Initializes the driver and performs the Click default configuration which sets the sample rate to 40 Hz, gyroscope resolution to 374 dps, and enables the data ready interrupt.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
gyro7_cfg_t gyro7_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
gyro7_cfg_setup( &gyro7_cfg );
GYRO7_MAP_MIKROBUS( gyro7_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == gyro7_init( &gyro7, &gyro7_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( GYRO7_ERROR == gyro7_default_cfg ( &gyro7 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Waits for the data ready interrupt, then reads the values of X and Y gyroscope axis as well as the chip internal temperature and displays the results on the USB UART. The data sample rate is set to 40Hz by default, therefore the data is being read approximately every 25ms.
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 dps\r\n", x_axis );
log_printf( &logger, " Y : %.2f dps\r\n", y_axis );
}
if ( GYRO7_OK == gyro7_read_temperature ( &gyro7, &temperature ) )
{
log_printf( &logger, " Temperature : %.2f C\r\n\n", temperature );
}
}
}

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.
USB-C Sink 4 Click is a compact add-on board designed to enable devices to draw power through the USB Type-C interface. This board features the CYPD3178, a USB Type-C power sink controller from Infineon. This Click board™ includes a controller with an integrated USB Type-C transceiver, load switch control with soft start, and system-level fault protection. It has configurable charging protocols, voltage negotiation, and an unpopulated SAFE 5V header for an alternate power supply.
