Software Support

We provide a library for the Thermo 27 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 Thermo 27 Click driver.

Example Description

This example demonstrates the use of Thermo 27 Click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and reads the device id, and after that resets the device and performs default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo27_cfg_t thermo27_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo27_cfg_setup( &thermo27_cfg );
THERMO27_MAP_MIKROBUS( thermo27_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == thermo27_init( &thermo27, &thermo27_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
uint16_t device_id;
thermo27_get_device_id( &thermo27, &device_id );
if ( THERMO27_DEVICE_ID != device_id )
{
log_error( &logger, " Communication error." );
for ( ; ; );
}
if ( THERMO27_ERROR == thermo27_default_cfg( &thermo27 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, " ======================= \r\n");
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART at a rate of once per second.

void application_task ( void )
{
float temperature;
uint8_t status;
thermo27_get_alert_reg( &thermo27, &status );
if ( THERMO27_DATA_READY_FLAG & status )
{
thermo27_read_temp( &thermo27, &temperature );
log_printf( &logger, " Temperature: %f degC \r\n", temperature );
log_printf( &logger, " ======================= \r\n");
}
}

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.Thermo27

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.
