Altitude 3 Click allows high-resolution barometric pressure measurement, by utilizing the ICP-10100, an integrated barometric pressure and temperature sensor.
We provide a library for the Altitude3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Altitude3 Click driver.
Config Object Initialization function.
void altitude3_cfg_setup ( altitude3_cfg_t *cfg );
Initialization function.
ALTITUDE3_RETVAL altitude3_init ( altitude3_t ctx, altitude3_cfg_t cfg );
Click Default Configuration function.
void altitude3_default_cfg ( altitude3_t *ctx );
Function sends a command to perform a SW Reset of the device.
void altitude3_soft_reset ( altitude3_t *ctx );
Function reads results of AD conversion, which consists of the 16bit temperature and 24bit
pressure data in determined order.
uint8_t altitude3_read_adc_results ( altitude3_t *ctx, uint8_t read_order );
Function performs a calibration data reading, only once, and then reads a temperature and pressure
data and calculates these values
to standard units. Also calculates the altitude depending on the temperature and pressure data.
uint8_t altitude3_get_data ( altitude3_t *ctx, uint8_t read_order );
This application enables high-resolution barometric pressure measurement.
The demo application is composed of two sections :
Initializes I2C interface and performs a SW Reset of the device.
void application_init ( void )
{
log_cfg_t log_cfg;
altitude3_cfg_t cfg;
/**
* 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.
altitude3_cfg_setup( &cfg );
ALTITUDE3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
altitude3_init( &altitude3, &cfg );
altitude3_default_cfg ( &altitude3 );
log_printf( &logger, "** Altitude 3 Click is initialized **\r\n\r\n" );
}
Selects the desired measurement mode and data reading order, and after that calculates the temperature, pressure and altitude data to standard units and shows results to uart terminal.
void application_task ( void )
{
uint8_t response;
response = altitude3_measurement_mode( &altitude3, ALTITUDE3_NORMAL_T_FIRST );
Delay_ms ( 100 );
response = altitude3_get_data( &altitude3, response );
if ( response != ALTITUDE3_ERROR )
{
log_printf( &logger, "Temperature is : %d C\r\n", ( int16_t ) altitude3.sens_data.temperature );
log_printf( &logger, "Pressure is : %u mbar[hPa]\r\n", ( uint16_t ) altitude3.sens_data.pressure );
log_printf( &logger, "Altitude is : %d m\r\n\r\n", ( int16_t ) altitude3.sens_data.altitude );
Delay_ms ( 400 );
}
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
