Click library

Software Support

We provide a library for the Thermostat3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Thermostat3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This application enables usage of the general purpose Thermostat click to be used with temperature sensors.

The demo application is composed of two sections :

Application Init

Initialization driver init

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
Delay_ms( 100 );
// Click initialization.
THERMOSTAT3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
thermostat3_init( &thermostat3, &cfg );
// Power on delay
Delay_ms( 200 );
log_printf( &logger, "---- Start Thermostat 3 ----\r\n" );
}

Application Task

Waits for valid user input and executes functions based on set of valid commands

void application_task ( void )
{
// Task implementation.
float internal_temp;
float thermocouple_temp;
thermostat3_process( &thermostat3, &temp_val );
log_printf( &logger, "# Internal Temperature: %.2f", internal_temp );
Delay_ms( 200 );
log_printf( &logger, "# Thermocouple Temperature: %.2f", thermocouple_temp );
Delay_ms( 200 );
if( thermostat3.relay_flag == 1)
{
thermostat3.relay_flag = 0;
log_printf( &logger, "# Relay OFF\r\n" );
}
else
{
thermostat3.relay_flag = 1;
log_printf( &logger, "# Relay ON\r\n" );
}
Delay_ms( 200 );
if( thermostat3.fault_flag == 1 )
{
thermostat3.fault_flag = 0;
log_printf( &logger, "# Fault status -- OFF\r\n" );
}
else
{
thermostat3.fault_flag = 1;
log_printf( &logger, "# Fault status -- ON\r\n" );
}
Delay_ms( 200 );
if( thermostat3.fault_flag == 1 )
{
thermostat3.f_error++;
if( thermostat3.f_error > 3 )
{
thermostat3.f_error = 0;
}
display_fault( thermostat3.f_error );
thermostat3.fault_status = thermostat3_get_fault_data( &temp_val, 0x01 << thermostat3.f_error );
if ( thermostat3.fault_status == 1 )
{
log_printf( &logger, " -- ERROR\r\n" );
}
else
{
log_printf( &logger, " -- OK\r\n" );
}
}
}

Note

  • Additional Functions : -void _displayFault( uint8_t f_error ) - Display fault

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
