Thermo 20 Click is a compact add-on board that provides an accurate temperature measurement. This board features the TSYS03, a miniature digital temperature sensor that comes up with factory calibrated, highly accurate temperature data from TE Connectivity.
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.
This library contains API for Thermo20 Click driver.
thermo20_cfg_setup
Config Object Initialization function.
void thermo20_cfg_setup ( thermo20_cfg_t *cfg );
thermo20_init
Initialization function.
err_t thermo20_init ( thermo20_t *ctx, thermo20_cfg_t *cfg );
thermo20_default_cfg
Click Default Configuration function.
err_t thermo20_default_cfg ( thermo20_t *ctx );
thermo20_set_cmd
Send command function.
err_t thermo20_set_cmd ( thermo20_t *ctx, uint8_t cmd );
thermo20_start_conversion
Start conversion function.
void thermo20_start_conversion ( thermo20_t *ctx );
thermo20_get_temperature
Get temperature data function.
float thermo20_get_temperature ( thermo20_t *ctx );
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 :
Initialization communication modules(I2C, UART). Resets device and read Serial Number.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
thermo20_cfg_t thermo20_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
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 " );
}
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 )
{
thermo20_start_conversion( &thermo20 );
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.

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.
