Click library

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

Software Support

We provide a library for the Manometer2 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 Manometer2 Click driver.

Standard key functions :

• Config Object Initialization function.

  void manometer2_cfg_setup ( manometer2_cfg_t *cfg );

• Initialization function.

  MANOMETER2_RETVAL manometer2_init ( manometer2_t ctx, manometer2_cfg_t cfg );

Example key functions :

• Generic read data function uint32_t manometer2_read_command ( manometer2_t *ctx, uint8_t reg_address );

• Function read coeffitient

  void manometer2_read_coef ( manometer2_t *ctx );

• Get pressure data function float manometer2_get_pressure ( manometer2_t *ctx, uint8_t oversampling_ratio );

Examples Description

This application is digital pressure sensor.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, initialization Manometer 2 sensor MS5525DSO-SB001GS by read coeffitient value and start write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    manometer2_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.

    manometer2_cfg_setup( &cfg );
    MANOMETER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    manometer2_init( &manometer2, &cfg );

    manometer2_read_coef( &manometer2 );
    log_printf( &logger, "        Initialization \r\n" );
    log_printf( &logger, "----------------------------- \r\n" );
    Delay_100ms( );
}

Application Task

This is a example which demonstrates the use of Manometer 2 Click board. Measured pressure and temperature value from sensor, calculate pressure [ PSI ] and temperature [ �C ], results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for aproximetly every 3 sec when the data value changes.

void application_task (  )
{
    float temperature;
    float pressure;

    temperature = manometer2_get_temperature( &manometer2, MANOMETER2_CONVERT_4096 );
    Delay_10ms( );

    pressure = manometer2_get_pressure( &manometer2, MANOMETER2_CONVERT_4096 );
    Delay_10ms( );

    log_printf( &logger, " Pressure :  %.2f PSI \r\n", pressure );
    log_printf( &logger, " Temperature: %.2f C \r\n", temperature );
    log_printf( &logger, "----------------------------- \r\n" );

    Delay_1sec( );
    Delay_1sec( );
    Delay_1sec( );
} 

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.Manometer2

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.
