Click library

  • Author : Luka Filipovic
  • Date : Sep 2021.
  • Type : SPI type

Software Support

We provide a library for the Thermo21 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 Thermo21 Click driver.

Standard key functions :

Example key functions :

Example Description

This example application showcases ability of the click board to read temperature data.

The demo application is composed of two sections :

Application Init

Initialization of communication modules(SPI, UART).

void application_init ( void )
{
log_cfg_t log_cfg;
thermo21_cfg_t thermo21_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo21_cfg_setup( &thermo21_cfg );
THERMO21_MAP_MIKROBUS( thermo21_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == thermo21_init( &thermo21, &thermo21_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Read and log temperautre every half second.

void application_task ( void )
{
float temperature = 0;
if ( !thermo21_temperature_read( &thermo21, &temperature ) )
{
log_printf( &logger, " > Temperature[degC]: %.2f\r\n", temperature );
}
Delay_ms( 500 );
}

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.Thermo21

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.
