Click library

  • Author : Stefan Filipovic
  • Date : Jan 2023.
  • Type : SPI type

Software Support

We provide a library for the Thermo 29 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 Thermo 29 Click driver.

Example Description

This example demonstrates the use of Thermo 29 click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger, and performs the click default configuration which enables

continuous conversion and sets the conversion rate to 1 Hz with a data ready flag enabled on the alert pin. After that, reads and displays the device 48-bit unique ID.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo29_cfg_t thermo29_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo29_cfg_setup( &thermo29_cfg );
THERMO29_MAP_MIKROBUS( thermo29_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == thermo29_init( &thermo29, &thermo29_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( THERMO29_ERROR == thermo29_default_cfg ( &thermo29 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
uint16_t unique_id[ 3 ];
if ( THERMO29_OK == thermo29_read_unique_id ( &thermo29, unique_id ) )
{
log_printf ( &logger, " Device Unique ID: 0x%.2X%.2X%.2X\r\n",
unique_id[ 0 ], unique_id[ 1 ], unique_id[ 2 ] );
}
log_info( &logger, " Application Task " );
}

Application Task

Waits for the data ready alert flag, then reads the temperature measurement in Celsius

and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
float temperature;
// Wait for the data ready alert flag
while ( thermo29_get_alert_pin ( &thermo29 ) );
if ( ( THERMO29_OK == thermo29_clear_alert_status ( &thermo29 ) ) &&
( THERMO29_OK == thermo29_read_temperature ( &thermo29, &temperature ) ) )
{
log_printf ( &logger, " Temperature: %.2f degC\r\n\n", temperature );
}
}

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.Thermo29

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.
