  • Date : Jul 2021.
  • Type : I2C type

Software Support

We provide a library for the Thermo20 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 Thermo20 Click driver.

Standard key functions :

Example key functions :

Example Description

This example showcases the ability of Thermo 20 Click board to

read it's serial number. It can read themperature and measure from -40degC to 120degC.

The demo application is composed of two sections :

Application Init

Initialization communication modules(I2C, UART). Resets device and read Serial Number.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo20_cfg_t thermo20_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo20_cfg_setup( &thermo20_cfg );
THERMO20_MAP_MIKROBUS( thermo20_cfg, MIKROBUS_1 );
err_t init_flag = thermo20_init( &thermo20, &thermo20_cfg );
if ( I2C_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
thermo20_default_cfg ( &thermo20 );
uint32_t ser_numb = thermo20_get_serial_number( &thermo20 );
log_printf( &logger, " > Serial Number: %lu\r\n", ser_numb );
log_info( &logger, " Application Task " );
}

Application Task

In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value,

and calculates temperature in degrees C.

void application_task ( void )
{
float temperature = thermo20_get_temperature( &thermo20 );
log_printf( &logger, " > Temperature[deg C]: %.2f\r\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.Thermo20

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.
