Click library

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

Software Support

We provide a library for the Airquality5 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 Airquality5 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void airquality5_cfg_setup ( airquality5_cfg_t *cfg );

  • Initialization function.

    AIRQUALITY5_RETVAL airquality5_init ( airquality5_t ctx, airquality5_cfg_t cfg );

  • Click Default Configuration function.

    void airquality5_default_cfg ( airquality5_t *ctx );

Example key functions :

  • Functions for write data in register.

    void airq5_write_data ( airquality5_t *ctx, uint8_t reg, uint16_t data_b );

  • Functions for read data from register.

    uint16_t airq5_read_data ( airquality5_t *ctx, uint8_t reg );

  • Functions for configuration.

    void airq5_set_configuration ( airquality5_t *ctx, uint16_t config );

Examples Description

This application can detect gas pollution for a number of different gases.

The demo application is composed of two sections :

Application Init

Initializes device and configuration chip.


void application_init ( void )
{
    log_cfg_t log_cfg;
    airquality5_cfg_t cfg;
    airquality5.data_config = 0x8583;

    /** 
     * 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 ----" );

    airquality5_cfg_setup( &cfg );
    AIRQUALITY5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    airquality5_init( &airquality5, &cfg );
}

Application Task

Reads the values of CO, NH3 and NO2 sensor and logs data on USBUART every 500ms.


void application_task ( void )
{
    uint16_t NO2_sensor_data;
    uint16_t NH3_sensor_data;
    uint16_t CO_sensor_data;

    CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );

    NO2_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NO2 );
    log_printf( &logger, " NO2 data: %d\r\n", NO2_sensor_data );

    NH3_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_NH3 );
    log_printf( &logger, " NH3 data: %d\r\n", NH3_sensor_data );

    CO_sensor_data = airq5_read_sensor_data( &airquality5, AIRQ5_DATA_CHANNEL_CO );
    log_printf( &logger," CO data: %d\r\n", CO_sensor_data );

    log_printf( &logger, " -------- ");
    Delay_ms ( 200 );
}  

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.Airquality5

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.

Angle 8 Click

0

Angle 8 Click is a compact add-on board that detects the absolute angular position of a permanent magnet. This board features the MA782GGU, a low-power angle sensor with integrated wake-up angle detection from Monolithic Power Systems. With its power cycling ability, the MA782GGU can be optimized for applications that require low average power. It supports a wide range of magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations. Fast data acquisition and processing provides accurate angle measurement at an applied magnetic field of 60mT, alongside magnetic field strength detection with programmable thresholds. This Click board™ is suitable for general-purpose angle measurements, in embedded motion control applications, as a power/speed control trigger solution, and more.
