Ammonia Click

Ammonia Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

• Author : MikroE Team
• Date : Jul 2020.
• Type : SPI type

Software Support

Example Description

This demo application reads ADC value.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ammonia

Example Key Functions

• ammonia_cfg_setup Config Object Initialization function.

void ammonia_cfg_setup ( ammonia_cfg_t *cfg );

• ammonia_init Initialization function.

err_t ammonia_init ( ammonia_t *ctx, ammonia_cfg_t *cfg );

• ammonia_heater Sensor heater function.

void ammonia_heater( ammonia_t *ctx, uint8_t state );

• ammonia_data_read Read data function.

uint32_t ammonia_data_read( ammonia_t *ctx );

Application Init

Initalizes SPI driver, turns on the heater, and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ammonia_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.

    ammonia_cfg_setup( &cfg );
    AMMONIA_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ammonia_init( &ammonia, &cfg );
    Delay_ms ( 100 );

    ammonia_heater( &ammonia, AMMONIA_HEATER_ON );
    Delay_ms ( 1000 );

    log_printf( &logger, "-------------------- \r\n" );
    log_printf( &logger, "   Ammonia  Click    \r\n" );
    log_printf( &logger, "-------------------- \r\n" );
}

Application Task

This is an example that shows the capabilities of the ADC 9 Click by reading ADC value and displaying it via UART.

void application_task ( void )
{
    spi_adc_value = ammonia_data_read( &ammonia );

    log_printf( &logger, "ADC value: %s \r\n", spi_adc_value );

    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
