TPS Pressure 500PG Click

TPS Pressure 500PG 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.

Click Library

  • Author : Stefan Filipovic
  • Date : Sep 2025.
  • Type : I2C type

Software Support

Example Description

This example demonstrates the use of the TPS Pressure 500PG Click board. The application continuously measures and logs the pressure in millibars and the temperature in degrees Celsius.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TPSPressure500PG

Example Key Functions

  • tpspressure500pg_cfg_setup This function initializes Click configuration structure to initial values.
void tpspressure500pg_cfg_setup ( tpspressure500pg_cfg_t *cfg );
  • tpspressure500pg_init This function initializes all necessary pins and peripherals used for this Click board.
err_t tpspressure500pg_init ( tpspressure500pg_t *ctx, tpspressure500pg_cfg_t *cfg );
  • tpspressure500pg_default_cfg This function executes a default configuration of TPS Pressure 500PG Click board.
err_t tpspressure500pg_default_cfg ( tpspressure500pg_t *ctx );
  • tpspressure500pg_read_data This function reads pressure (mBar) and temperature (degC) values.
err_t tpspressure500pg_read_data ( tpspressure500pg_t *ctx, float *press, float *temp );

Application Init

Initializes the driver, checks communication, and applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    tpspressure500pg_cfg_t tpspressure500pg_cfg;  /**< Click config object. */

    /** 
     * 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.
    tpspressure500pg_cfg_setup( &tpspressure500pg_cfg );
    TPSPRESSURE500PG_MAP_MIKROBUS( tpspressure500pg_cfg, MIKROBUS_POSITION_TPSPRESSURE500PG );
    if ( I2C_MASTER_ERROR == tpspressure500pg_init( &tpspressure500pg, &tpspressure500pg_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( TPSPRESSURE500PG_ERROR == tpspressure500pg_default_cfg ( &tpspressure500pg ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads and logs pressure and temperature values every 100 ms.

void application_task ( void )
{
    float pressure = 0;
    float temperature = 0;
    if ( TPSPRESSURE500PG_OK == tpspressure500pg_read_data ( &tpspressure500pg, &pressure, &temperature ) )
    {
        log_printf( &logger, " Pressure: %.2f mBar\r\n", pressure );
        log_printf( &logger, " Temperature: %.2f degC\r\n\n", temperature );
    }
    Delay_ms ( 100 );
}

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.
