Thermo 23 click

Thermo 23 Click is a compact add-on board that provides an accurate temperature measurement. This board features the TMP144, a high-precision digital temperature sensor from Texas Instruments. The temperature sensor in the TMP144 is the chip itself, that houses temperature sensor circuitry, 12-bit analog-to-digital converter (ADC), a control logic, and a serial interface block in one package. Characterized by its high accuracy (up to ±0.5°C typical) and high resolution of 0.0625°C, this temperature sensor provides temperature data to the host controller with a configurable UART interface.

Click library

  • Author : Stefan Filipovic
  • Date : Mar 2022.
  • Type : UART type

Software Support

We provide a library for the Thermo 23 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 23 Click driver.

Example Description

This example demonstrates the use of Thermo 23 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.

void application_init ( void )
{
log_cfg_t log_cfg;
thermo23_cfg_t thermo23_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
thermo23_cfg_setup( &thermo23_cfg );
THERMO23_MAP_MIKROBUS( thermo23_cfg, MIKROBUS_1 );
if ( UART_ERROR == thermo23_init( &thermo23, &thermo23_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( THERMO23_ERROR == thermo23_default_cfg ( &thermo23 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in Celsius and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
float temperature;
if ( THERMO23_OK == thermo23_read_temperature ( &thermo23, &temperature ) )
{
log_printf( &logger, " Temperature : %.2f C\r\n\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.Thermo23

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.
