Temp-Log 3 Click

Temp-Log 3 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This application measures temperature.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempLog3

Example Key Functions

• templog3_cfg_setup Config Object Initialization function.

void templog3_cfg_setup ( templog3_cfg_t *cfg );

• templog3_init Initialization function.

err_t templog3_init ( templog3_t *ctx, templog3_cfg_t *cfg );

• templog3_default_cfg Click Default Configuration function.

void templog3_default_cfg ( templog3_t *ctx );

• templog3_set_temp Set Temperature function.

uint8_t templog3_set_temp ( templog3_t *ctx, uint8_t temp_sel, float temp_in );

• templog3_eeprom_byte_write EEPROM Single Write function.

void templog3_eeprom_byte_write ( templog3_t *ctx, uint8_t reg_addr, uint8_t data_in, uint8_t eeprom_mode );

• templog3_eeprom_sequential_read EEPROM Sequential Read function.

uint8_t templog3_eeprom_sequential_read ( templog3_t *ctx, uint8_t reg_addr, uint8_t *data_out, uint16_t num_bytes );

Application Init

Initializes I2C interface and performs a device default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    templog3_cfg_t cfg;

    /** 
     * 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.

    templog3_cfg_setup( &cfg );
    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 Click 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, and logs the results to the USB UART.

void application_task ( void )
{
    float temperature;
    uint8_t ret_status;

    templog3_wait_conv_done( &templog3 );

    ret_status = templog3_get_temp( &templog3, TEMPLOG3_TEMP_AMBIENT_REG, &temperature );

    log_printf( &logger, "**  Ambient temperature is : %.2f C  **\r\n", temperature );
    
    check_limit_status( ret_status );
    
    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 of the 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.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
