Click library

Software Support

We provide a library for the TempLog3 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 TempLog3 Click driver.

Examples Description

This application measures temperature.

The demo application is composed of two sections :

Application Init

Initializes I2C interface and performs a device configuration for properly working. Also sets the temperature limit to the desired values.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
TEMPLOG3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
templog3_init( &templog3, &cfg );
Delay_ms( 500 );
templog3_default_cfg( &templog3 );
Delay_ms( 200 );
log_printf( &logger, "** Temp-Log 3 is initialized ** \r\n" );
}

Application Task

First ensures that the minimum conversion time is met, and then reads the ambient temperature calculated to the Celsius degrees.

void application_task ( void )
{
float temperature;
ret_status = templog3_get_temp( &templog3, TEMPLOG3_TEMP_AMBIENT_REG, &temperature );
log_printf( &logger, "** Ambient temperature is : %.2f C **\r\n", temperature );
Delay_ms( 300 );
}

Note

The temperature range that can be measured or written is from -40 to +125 Celsius degrees. The user can change the measured temperature resolution, but the range remains the same. The limit temperature resolution is always a 10bit, or 0.25 Celsius degrees. If user wants to enable the EEPROM Write Protection, the A0 pin on the device must be set to the high voltage level

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.

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.
