Temp Probe Click

Temp Probe 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 is an example that demonstrates the use of the Temp Probe Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempProbe

Example Key Functions

• tempprobe_cfg_setup Config Object Initialization function.

  void tempprobe_cfg_setup ( tempprobe_cfg_t *cfg );

• tempprobe_init Initialization function.

  err_t tempprobe_init ( tempprobe_t *ctx, tempprobe_cfg_t *cfg );

• tempprobe_default_cfg Click Default Configuration function.

  err_t tempprobe_default_cfg ( tempprobe_t *ctx );

• tempprobe_write_word Word Write function.

  err_t tempprobe_write_word ( tempprobe_t *ctx, uint16_t reg_addr, uint32_t data_in );

• tempprobe_read_bytes Byte Read function.

  err_t tempprobe_read_bytes( tempprobe_t *ctx, uint16_t reg_addr, uint8_t *data_out, uint8_t n_bytes );

• tempprobe_read_temp Temperature Read function.

  uint8_t tempprobe_read_temp ( tempprobe_t *ctx, uint16_t sel_channel, float *data_out );

Application Init

Initializes SPI interface and performs a device configuration for properly working and configures the desired channels.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  
    tempprobe_cfg_t tempprobe_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    tempprobe_cfg_setup( &tempprobe_cfg );
    TEMPPROBE_MAP_MIKROBUS( tempprobe_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == tempprobe_init( &tempprobe, &tempprobe_cfg ) ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }
    tempprobe_reset( &tempprobe );
    Delay_ms ( 300 );
    if ( TEMPPROBE_ERROR == tempprobe_default_cfg( &tempprobe ) ) 
    {
        log_error( &logger, " Config Error " );
        for ( ; ; );
    }
    Delay_ms ( 300 );
 
    log_info( &logger, " Application Task " );
}

Application Task

Measure temperatures from all sensors and display the measurements on the serial port.

void application_task ( void ) 
{
    float temperature_k = 0;
    float temperature_pn = 0;
    tempprobe_write_byte( &tempprobe, TEMPPROBE_REG_COMM_STATUS, TEMPPROBE_START_CONV );
    while ( TEMPPROBE_NO_BUSY_STATE != tempprobe_check_busy( &tempprobe ) );
 
    tempprobe_read_temp( &tempprobe, TEMPPROBE_REG_PN_JUNCTION_CONV_RES, &temperature_pn );
    log_printf( &logger, " PN-Junction: %.2f C\r\n", temperature_pn );
    tempprobe_read_temp( &tempprobe, TEMPPROBE_REG_THERMO_K_CONV_RES, &temperature_k );
    log_printf( &logger, " Thermo K:    %.2f C\r\n", temperature_k );
 
    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

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.
