Click library

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

Software Support

We provide a library for the Ammonia 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 Ammonia Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ammonia_cfg_setup ( ammonia_cfg_t *cfg );

  • Initialization function.

    AMMONIA_RETVAL ammonia_init ( ammonia_t ctx, ammonia_cfg_t cfg );

Example key functions :

  • Sensor heater function

    void ammonia_heater ( ammonia_t *ctx, uint8_t state );

  • Read data function

    uint32_t ammonia_data_read ( ammonia_t *ctx );

Examples Description

This demo application reads ADC value.

The demo application is composed of two sections :

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 );
}

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.Ammonia

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.

H-Bridge 2 click

5

H-Bridge 2 click can be used to drive a motor by utilizing a specific configuration of the output stage MOSFETs, known as the H-bridge. This configuration enables H-Bridge 2 click to drive a motor with up to 1.2A and 15V, providing control of the speed and direction, as well as the dynamic (rheostatic) braking capability.
