Click library

  • Author : Stefan Filipovic
  • Date : Aug 2022.
  • Type : SPI type

Software Support

We provide a library for the Thermo 25 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 25 Click driver.

Standard key functions :

Example key functions :

  • thermo25_check_communication This function sets the operating mode to shutdown, then reads and verifies the device ID, and switches back to the continuous mode.
  • thermo25_read_temperature This function reads the temperature measurements in degrees Celsius.
    err_t thermo25_read_temperature ( thermo25_t *ctx, float *temperature );
  • thermo25_set_mode This function sets the device operating mode to shutdown or continuous mode by using SPI serial interface.
    err_t thermo25_set_mode ( thermo25_t *ctx, uint8_t mode );

Example Description

This example demonstrates the use of Thermo 25 click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger, and checks the communication by setting the operating mode to shutdown, reading and verifying the device ID, and switching back to the continuous mode.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo25_cfg_t thermo25_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo25_cfg_setup( &thermo25_cfg );
THERMO25_MAP_MIKROBUS( thermo25_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == thermo25_init( &thermo25, &thermo25_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
{
log_error( &logger, " Check communication." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
float temperature;
if ( THERMO25_OK == thermo25_read_temperature ( &thermo25, &temperature ) )
{
log_printf ( &logger, " Temperature: %.2f degC\r\n\n", temperature );
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.Thermo25

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.
