Click library

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

Software Support

We provide a library for the Pressure8 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 Pressure8 Click driver.

Standard key functions :

  • pressure8_cfg_setup Config Object Initialization function.

    void pressure8_cfg_setup ( pressure8_cfg_t *cfg ); 
  • pressure8_init Initialization function.

    err_t pressure8_init ( pressure8_t *ctx, pressure8_cfg_t *cfg );

Example key functions :

  • pressure8_get_pressure Functions for get Pressure data

    float pressure8_get_pressure ( pressure8_t *ctx, uint8_t press_format );
  • pressure8_get_device_status Functions for get device status

    uint8_t pressure8_get_device_status ( pressure8_t *ctx );
  • pressure8_set_psi_range Functions for set PSI range

    void pressure8_set_psi_range ( pressure8_t *ctx, float psi_min, float psi_max );

Examples Description

This application reads pressure data.

The demo application is composed of two sections :

Application Init

Initialization device and logger module, reset device and set PSI range.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure8_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.
    pressure8_cfg_setup( &cfg );
    PRESSURE8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure8_init( &pressure8, &cfg );

    pressure8_device_reset( &pressure8 );
    pressure8_set_psi_range( &pressure8, 0, 25 );
    Delay_ms ( 1000 );

    log_info( &logger, " Application Task " );
}

Application Task

Reads pressure data in mBar and logs it on the USB UART once per second.

void application_task ( void )
{
    float pressure = 0;

    pressure = pressure8_get_pressure( &pressure8, PRESSURE8_DATA_IN_MBAR );
    log_printf( &logger, " Pressure: %.1f mBar\r\n", pressure );

    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.Pressure8

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.

Smart Card 2 Click is a compact add-on board for reading smart cards. This board features Microchip’s SEC1210, a low-power single-chip Smart Card controller with a UART interface. The SEC1210 bridge controller uses a combination of hardware and software to deliver high-performance and flexible design customization options. It is fully compliant with standards like ISO/IEC 7816, EMV 4.2/4.3, ETSI TS 102 221, and PC/SC, utilizing TrustSpan™ technology that enables digital systems to communicate securely, process, move and store information. With its onboard card holder, it supports data processing with 2FF smart cards, and with an additional connector for external connection, it also allows the processing of a standard 1FF card.
