Software Support

We provide a library for the TempHum16 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.

Example Description

This library contains API for the Temp&Hum 16 Click driver. This demo application shows an example of humidity and temperature measurement.

The demo application is composed of two sections :

Application Init

Initialization of SPI or I2C module and log UART. After driver initialization and default settings, the app display retrieves the sensor parameters such as temperature and humidity.

void application_init ( void ) {
log_cfg_t log_cfg;
temphum16_cfg_t temphum16_cfg;
// Logger initialization.
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 115200;
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
temphum16_cfg_setup( &temphum16_cfg );
TEMPHUM16_MAP_MIKROBUS( temphum16_cfg, MIKROBUS_1 );
err_t init_flag = temphum16_init( &temphum16, &temphum16_cfg );
if ( ( init_flag == I2C_MASTER_ERROR ) || ( init_flag == SPI_MASTER_ERROR ) ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
temphum16_default_cfg ( &temphum16 );
log_info( &logger, " Application Task " );
Delay_ms( 100 );
temphum16_get_device_id( &temphum16, &device_id );
log_printf( &logger, "-----------------------\r\n" );
log_printf( &logger, " Check communication \r\n" );
if ( device_id == TEMPHUM16_DEVICE_ID ){
log_printf( &logger, " Successful \r\n" );
} else {
log_printf( &logger, " Failed \r\n" );
for ( ; ; );
}
log_printf( &logger, "-----------------------\r\n" );
log_printf( &logger, " Start measurements \r\n" );
log_printf( &logger, "-----------------------\r\n" );
}

Application Task

This is an example that shows the use of a Temp&Hum 16 Click boardâ„¢. Logs humidity [ % ] and temperature [ degree Celsius ] data. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) {
if ( temphum16_check_ready( &temphum16 ) == TEMPHUM16_DRDY ) {
temphum16_get_temperature( &temphum16, &temperature );
log_printf( &logger, " Temperature : %.2f C\r\n", temperature );
temphum16_get_humidity( &temphum16, &humidity );
log_printf( &logger, " Humidity : %.2f %%\r\n", humidity );
log_printf( &logger, "-----------------------\r\n" );
Delay_ms( 1000 );
}
}

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.TempHum16

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.
