Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Thermo4 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 Thermo4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    ‍void thermo4_cfg_setup ( thermo4_cfg_t *cfg );

    - Initialization function.

    ‍THERMO4_RETVAL thermo4_init ( thermo4_t *ctx, thermo4_cfg_t *cfg );

  • Click Default Configuration function.

    ‍void thermo4_default_cfg ( thermo4_t *ctx );

Example key functions :

  • This function reads temperature values in Celsius format.

    ‍float thermo4_read_temperature_c ( thermo4_t *ctx );

    - This function reads temperature values in Farenheit format.

    ‍float thermo4_read_temperature_f ( thermo4_t *ctx );

  • This function is used to reset the sensor.

    ‍void thermo4_reset ( thermo4_t *ctx );

    Examples Description

‍This demo example returns temperature values in three different format.

The demo application is composed of two sections :

Application Init

‍Initializes the driver and makes an initial log.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo4_cfg_t cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
// Click initialization.
thermo4_cfg_setup( &cfg );
THERMO4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
thermo4_init( &thermo4, &cfg );
log_info( &logger, "---- Application Init ----" );
}

thermo4_cfg_setup
void thermo4_cfg_setup(thermo4_cfg_t *cfg)
Config Object Initialization function.
thermo4_init
THERMO4_RETVAL thermo4_init(thermo4_t *ctx, thermo4_cfg_t *cfg)
Initialization function.

Application Task

‍Returns temperature values from the sensor.

void application_task ( void )
{
temp_in_celsius = thermo4_read_temperature_c( thermo4 );
temp_in_faren = thermo4_read_temperature_f( thermo4 );
temp_in_kelvin = thermo4_read_temperature_k( thermo );
log_printf(" Temperature celsius : %f %c\r\n", temp_in_celsius, deg_cel);
log_printf(" Temperature farenheit : %f %c\r\n", temp_in_faren, deg_far);
log_printf(" Temperature kelvin : %f K\r\n", temp_in_kelvin);
Delay_ms ( 1000 );
}
thermo4_read_temperature_c
float thermo4_read_temperature_c(thermo4_t *ctx)
Read Temperature in Celsius function.
thermo4_read_temperature_f
float thermo4_read_temperature_f(thermo4_t *ctx)
Read Temperature in Fahrenheit function.
thermo4_read_temperature_k
float thermo4_read_temperature_k(thermo4_t *ctx)
Read Temperature in Kelvin function.
application_task
void application_task(void)
Definition main.c:77

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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Thermo4

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.
