Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

We provide a library for the TempLog4 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 TempLog4 Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void templog4_cfg_setup ( templog4_cfg_t *cfg );

  - Initialization function.

  ‍TEMPLOG4_RETVAL templog4_init ( templog4_t *ctx, templog4_cfg_t *cfg );

• Click Default Configuration function.

  ‍void templog4_default_cfg ( templog4_t *ctx );

Example key functions :

• Generic Write function.

  ‍uint8_t templog4_write_reg ( templog4_t *ctx, uint8_t reg, uint16_t input_data );

  - Generic Read function.

  ‍uint8_t templog4_read_reg ( templog4_t *ctx, uint8_t reg, uint16_t *out_var );

• Set Address Pointer function.

  ‍void templog4_set_addr_ptr ( templog4_t *ctx, uint8_t addr );

  Examples Description

‍This application measures the temperature.

The demo application is composed of two sections :

Application Init

‍Initializes I2C interface and performs a device configuration for properly working.

void application_init ( void )
{
    log_cfg_t log_cfg;
    templog4_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    templog4_cfg_setup( &cfg );
    TEMPLOG4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    templog4_init( &templog4, &cfg );
    templog4_default_cfg ( &templog4 );
}

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;
 
    wait_conversion_done( );
 
    ret_status = templog4_get_temp( &templog4, TEMPLOG4_TEMP_AMBIENT_REG, &temperature );
 
    log_printf( &logger, "** Ambient temperature: %f C **\r\n", temperature );
 
    check_limit_status( );
 
    log_printf( &logger, "\r\n", temperature );
 
    Delay_ms ( 300 );
}  

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.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.TempLog4

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.
