Inclinometer 4 Click is a compact add-on board designed to measure angles of slope or elevation of an object concerning gravity's direction. This board features the FXLS8971CF, a 3-axis low-g MEMS accelerometer from NXP Semiconductor. The FXLS8971CF offers high-performance and low-power modes, with selectable full-scale ranges of ±2/4/8/16g and features such as selectable output data rates, motion detection, and a 144-byte output data buffer.

We provide a library for the Inclinometer 4 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 Inclinometer 4 Click driver.
inclinometer4_cfg_setup
Config Object Initialization function.
void inclinometer4_cfg_setup ( inclinometer4_cfg_t *cfg );
inclinometer4_init
Initialization function.
err_t inclinometer4_init ( inclinometer4_t *ctx, inclinometer4_cfg_t *cfg );
inclinometer4_default_cfg
Click Default Configuration function.
err_t inclinometer4_default_cfg ( inclinometer4_t *ctx );
inclinometer4_get_int2_pin
This function returns the interrupt 2 (INT2) pin logic state.
uint8_t inclinometer4_get_int2_pin ( inclinometer4_t *ctx );
inclinometer4_get_data
This function reads accel X, Y, and Z axis data in g and temperature in degrees Celsius.
err_t inclinometer4_get_data ( inclinometer4_t *ctx, inclinometer4_data_t *data_out );
inclinometer4_set_mode
This function sets the device operating mode to standby or active.
err_t inclinometer4_set_mode ( inclinometer4_t *ctx, uint8_t mode );
This example demonstrates the use of Inclinometer 4 click board by reading and displaying accel data (X, Y, and Z axis) as well as temperature measurements on the USB UART.
The demo application is composed of two sections :
Initializes the driver and performs the click default configuration which enables data ready interrupt on INT2 pin and sets full scale range to +/-2G and output data rate to 160ms.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
inclinometer4_cfg_t inclinometer4_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.
inclinometer4_cfg_setup( &inclinometer4_cfg );
INCLINOMETER4_MAP_MIKROBUS( inclinometer4_cfg, MIKROBUS_1 );
err_t init_flag = inclinometer4_init( &inclinometer4, &inclinometer4_cfg );
if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( INCLINOMETER4_ERROR == inclinometer4_default_cfg ( &inclinometer4 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Waits for a data ready interrupt, then reads and displays the accel data (X, Y, and Z axis) as well as temperature measurements on the USB UART.
void application_task ( void )
{
inclinometer4_data_t accel_data;
// Wait for a data ready interrupt
while ( inclinometer4_get_int2_pin ( &inclinometer4 ) );
if ( INCLINOMETER4_OK == inclinometer4_get_data ( &inclinometer4, &accel_data ) )
{
log_printf( &logger, " X: %.3f g\r\n", accel_data.x );
log_printf( &logger, " Y: %.3f g\r\n", accel_data.y );
log_printf( &logger, " Z: %.3f g\r\n", accel_data.z );
log_printf( &logger, " Temperature: %d degC\r\n\n", ( int16_t ) accel_data.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.
