Temp Log 6 Click

Temp-Log 6 Click is a temperature sensing Click board™, which features the MAX6642, a specifically designed IC, capable of measuring its own die temperature, as well as a temperature at a remote PN junction. This option makes Temp-Log 6 Click well-suited for monitoring the temperature of a CPU, GPU or FPGA, where the PN junction is typically a substrate PNP transistor on the die of the measured IC.

Click library

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

Software Support

We provide a library for the TempLog6 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 TempLog6 Click driver.

Standard key functions :

• Config Object Initialization function.

  void templog6_cfg_setup ( templog6_cfg_t *cfg );

• Initialization function.

  TEMPLOG6_RETVAL templog6_init ( templog6_t ctx, templog6_cfg_t cfg );

• Click Default Configuration function.

  void templog6_default_cfg ( templog6_t *ctx );

Example key functions :

• Writes one byte of data.

  void templog6_write_byte ( templog6_t *ctx, uint8_t reg, uint8_t data_buf );

• Reads one byte of data.

  uint8_t templog6_read_byte ( templog6_t *ctx, uint8_t reg );

• Gets the INT pin.

  uint8_t templog6_get_interrupt ( templog6_t *ctx );

Examples Description

The example starts off with the initialization and configuration of the Click and logger modules, tests the communication channel and reads and displays local and remote temperature values every second.

The demo application is composed of two sections :

Application Init

Initializes and configures the Click and logger modules and tests the communication for errors.

void application_init ( )
{
    log_cfg_t log_cfg;
    templog6_cfg_t cfg;

    uint8_t test;

    /** 
     * 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.

    templog6_cfg_setup( &cfg );
    TEMPLOG6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    templog6_init( &templog6, &cfg );

    // Test communication 

    test = templog6_read_byte( &templog6, TEMPLOG6_REG_MANUFACTURER_ID );

    if ( test == TEMPLOG6_MANUFACTURER_ID )
    {
        log_printf( &logger, "--- Comunication OK!!! ---\r\n" );
    }
    else
    {
        log_printf( &logger, "--- Comunication ERROR!!! ---\r\n" );
        for ( ; ; );
    }

    templog6_default_cfg( &templog6 );

    log_printf( &logger, "--- Start measurement ---\r\n" );
}

Application Task

Reads and displays local and remote temperature values every second.

void application_task ( void )
{
    float remote_temp;
    float local_temp;

    local_temp = templog6_read_byte( &templog6, TEMPLOG6_REG_LOCAL_TEMPERATURE );
    log_printf( &logger, "--- Local Temperature: %f C\r\n", local_temp );

    remote_temp = templog6_read_byte( &templog6, TEMPLOG6_REG_REMOTE_TEMPERATURE );
    log_printf( &logger, "--- Remote Temperature: %f C\r\n", remote_temp );

    log_printf( &logger, "-----------------------------\r\n" );
    Delay_ms ( 1000 );
}  

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.TempLog6

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.
