Click library

  • Author : Stefan Ilic
  • Date : Aug 2023.
  • Type : I2C type

Software Support

We provide a library for the Temp Alarm 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 Temp Alarm Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of Temp Alarm click board by reading and displaying

the temperature measurements and monitoring it.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the Local sensor critical temperature at 30 degC with hysteresis of 1 degC,

and Remote sensor alarm temperature at 30 degC.

void application_init ( void )
{
log_cfg_t log_cfg;
tempalarm_cfg_t tempalarm_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
tempalarm_cfg_setup( &tempalarm_cfg );
TEMPALARM_MAP_MIKROBUS( tempalarm_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == tempalarm_init( &tempalarm, &tempalarm_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( TEMPALARM_ERROR == tempalarm_default_cfg ( &tempalarm ) )
{
log_error( &logger, " Default configuration." );
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. Monitoring alarm and critical state.

void application_task ( void )
{
uint8_t flag_data = 0;
int8_t local_temp = 0;
float remote_temp = 0;
tempalarm_get_alarms( &tempalarm, &flag_data );
if ( 0 == ( TEMPALARM_ADC_BUSY_MASK & flag_data ) )
{
tempalarm_read_temperature ( &tempalarm, &local_temp );
tempalarm_read_remote_temperature( &tempalarm, &remote_temp );
log_printf( &logger, " Local temperature : %d degC \r\n" , ( int16_t ) local_temp );
log_printf( &logger, " Remote temperature : %.3f degC \r\n" , remote_temp );
log_printf( &logger, " -------------------------------- \r\n" );
}
{
log_printf( &logger, " Alarm is on, remote temperature \r\n" );
log_printf( &logger, " is higher then 30 degC \r\n" );
log_printf( &logger, " -------------------------------- \r\n" );
}
{
log_printf( &logger, " Alarm is on, local temperature \r\n" );
log_printf( &logger, " is higher then 30 degC \r\n" );
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.TempAlarm

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.
