Manometer click

Manometer click carries a piezoresistive silicon pressure sensor,the HSCMAND060PA3A3 from Honeywell, an industry-leading module with an extremely high accuracy of ±0.25%FSS BFSL.>

Click library

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

Software Support

We provide a library for the Manometer 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 Manometer Click driver.

Standard key functions :

• Config Object Initialization function.

  void manometer_cfg_setup ( manometer_cfg_t *cfg );

• Initialization function.

  MANOMETER_RETVAL manometer_init ( manometer_t ctx, manometer_cfg_t cfg );

Example key functions :

• Generic write function.

  void manometer_generic_write ( manometer_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

• Generic read function.

  void manometer_generic_read ( manometer_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

• Function read 16-bit data and convert to pressure in mbar.

  float manometer_get_pressure ( manometer_t *ctx );

Examples Description

This application carries a piezoresistive silicon pressure sensor.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C and start write log to Usart Terminal.

void application_init ( void )
{
 log_cfg_t log_cfg;
    manometer_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 ----" );

    manometer_cfg_setup( &cfg );
    MANOMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    manometer_init( &manometer, &cfg );
}

Application Task

This is a example which demonstrates the use of Manometer Click board.

void application_task ( void )
{
 float read_data;

    read_data = manometer_get_pressure( &manometer );
    Delay_10ms( );

    log_printf( &logger, " Pressure: %d mbar\r\n", read_data );

    read_data = manometer_get_temperature( &manometer );
    Delay_10ms( );

    log_printf( &logger, " Temperature:  %d C\r\n", read_data );
    log_printf( &logger, "--------------------------\r\n" );

    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.Manometer

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.
