Click library

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

Software Support

We provide a library for the NO22 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 NO22 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void no22_cfg_setup ( no22_cfg_t *cfg );

  • Initialization function.

    NO22_RETVAL no22_init ( no22_t ctx, no22_cfg_t cfg );

  • Click Default Configuration function.

    void no22_default_cfg ( no22_t *ctx );

Example key functions :

  • Function for reading ADC data

    uint16_t no22_read_data ( no22_t *ctx );

  • Function for reading ppb data

    float no22_get_ppb ( no22_t *ctx );

  • Function for setting pht pin

    uint8_t no22_set_pht_state ( no22_t *ctx, uint8_t state );

Examples Description

Measure the level of NO2

The demo application is composed of two sections :

Application Init

Driver init


void application_init ( void )
{
    log_cfg_t log_cfg;
    no22_cfg_t cfg;
    uint8_t error_data;

    /** 
     * 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.


    no22_cfg_setup( &cfg );
    NO22_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    no22_init( &no22, &cfg );

    error_data = no22_set_pht_state( &no22, NO22_PIN_STATE_LOW );

    if ( error_data == NO22_DEVICE_ERROR )
    {
        log_printf( &logger, "Device error \r\n" );
        for ( ; ; );
    }

    log_printf( &logger, "***** App init ***** \r\n" );
}

Application Task

Measures in span of 1 seconc ppb of NO2


void application_task ( )
{
    uint16_t temp_data_read;
    float data_ppb;

    temp_data_read = no22_read_data( &no22 );
    log_printf( &logger, "ADC: %d \n\r", temp_data_read );

    data_ppb = no22_get_ppb( &no22 );
    log_printf( &logger, "PPB: %f \r\n", data_ppb );

    log_printf( &logger, "___________________________\r\n" );

    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.NO22

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.

Matrix R Click

0

Matrix R Click is a mikroBUS add-on board with two red 5x7 matrices driven by two MAX7219 8-bit LED Display Drivers. The active area of each matrix is 7.62mm high and 5.08 mm wide. 7x5 is a standard resolution for displaying ASCII characters, so the Click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The Click communicates with the target MCU through the mikroBUS:tm: SPI interface with two separate Chip Select lines for each matrix (CSL for the left, CSR for the right). This board is designed to use a 5V power supply.

BT Audio 3 Click

0

BT Audio 3 Click is a compact add-on board with high-performing voice and audio post-processing capability for Bluetooth audio applications. This board features the BM83, a fully certified Bluetooth v5.0 stereo audio module from Microchip. The BM83 contains an onboard Bluetooth stack and audio profiles and supports 24-bit/96 kHz high-resolution audio formats to enable high-fidelity wireless audio. An integrated Digital Signal Processor (DSP) decodes AAC and SBC codecs and executes advanced audio and voice processing such as Wide-Band (WB) speech, Acoustic Echo Cancellation (AEC), and Noise Reduction (NR). Configured in Host mode, the BM83 allows data processing via the UART interface, and in addition, comes with many additional features such as audio control buttons, onboard microphones, LED indicators, and more.
