Click library

  • Author : Jelena Milosavljevic
  • Date : Jul 2021.
  • Type : I2C/SPI type

Software Support

We provide a library for the Smoke2 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Smoke2 Click driver.

Standard key functions :

  • smoke2_cfg_setup Config Object Initialization function.

    void smoke2_cfg_setup ( smoke2_cfg_t *cfg );
  • smoke2_init Initialization function.

    err_t smoke2_init ( smoke2_t *ctx, smoke2_cfg_t *cfg );
  • smoke2_default_cfg Click Default Configuration function.

    err_t smoke2_default_cfg ( smoke2_t *ctx );

Example key functions :

  • smoke2_get_int_pin This function eget state of int pin of Smoke 2 Click board.

    uint8_t smoke2_get_int_pin ( smoke2_t *ctx );
  • smoke2_write_data This function is generic for writing data to register of Smoke 2 Click board.

    void smoke2_write_data( smoke2_t *ctx, uint8_t reg, uint16_t tx_data );
  • smoke2_read_data This function is generic for reading data from registar of Smoke 2 Click board.

    uint16_t smoke2_read_data( smoke2_t *ctx, uint8_t reg );

Example Description

This example is made to see how Smoke 2 clicks work. The purpose of this example is that, depending on the way we choose, it collects data from the external environment about smoke, processes it, and prints it via the UART terminal.

The demo application is composed of two sections :

Application Init

Initialization of communication modules, additional pins, Mapping pins and configures device for measurement.


void application_init ( void ) 
{
    log_cfg_t log_cfg;            /**< Logger config object. */
    smoke2_cfg_t smoke2_cfg;      /**< Click config object. */

    /** 
     * 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.
    smoke2_cfg_setup( &smoke2_cfg );
    SMOKE2_MAP_MIKROBUS( smoke2_cfg, MIKROBUS_1 );
    err_t init_flag  = smoke2_init( &smoke2, &smoke2_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
        for ( ; ; );
    }

    smoke2_soft_reset( &smoke2 );
    smoke2_set_mode( &smoke2, SMOKE2_MODE_IDLE );

    uint16_t devid = smoke2_read_data( &smoke2, SMOKE2_REG_DEVID );
    log_printf( &logger, ">> ID:  0x%.2X\r\n", ( uint16_t ) ( devid & 0xFF ) );  
    log_printf( &logger, ">> REV: 0x%.2X\r\n", ( uint16_t ) ( ( devid >> 8 ) & 0xFF ) );
    Delay_ms ( 1000 );

    log_printf( &logger, ">> Configuration <<\r\n" );
    smoke2_default_cfg( &smoke2 ); 
    Delay_ms ( 1000 ); 

#if ( EXAMPLE_MODE == EXAMPLE_MODE_SMOKE )
    log_printf( &logger, ">> SMOKE MODE <<\r\n" );
    log_printf( &logger, ">> Calibration <<\r\n" );
    uint16_t calib_data = smoke2_smoke_calibration( &smoke2, 500 );
    log_printf( &logger, ">> Calibration data: %u\r\n", calib_data );
#elif ( EXAMPLE_MODE == EXAMPLE_MODE_PROXIMITY )
    log_printf( &logger, ">> PROXIMITY MODE <<\r\n" );
#endif
    log_info( &logger, " Application Task " );
}

Application Task

Example shows module working depending on example mode. We can choose between: EXAMPLE_MODE_PROXIMITY and EXAMPLE_MODE_SMOKE.


void application_task ( void ) 
{
#if ( EXAMPLE_MODE == EXAMPLE_MODE_SMOKE )
    smoke_example( &smoke2 );
#elif ( EXAMPLE_MODE == EXAMPLE_MODE_PROXIMITY )
    proximity_example( );
#endif
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Smoke2

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. UART terminal is available in all MikroElektronika compilers.

Oximeter 5 Click is a compact add-on board suitable for measuring blood oxygen saturation. This board features the MAX30102, integrated pulse oximetry, and heart-rate monitor module from Analog Devices. The MAX30102 includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. It operates on a single 1.8V power supply acquired from both mikroBUS™ power rails for the internal LEDs, communicating through a standard I2C compatible interface. The MAX30102 can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.

Current 5 Click

0

Current 5 Click is a compact add-on board that provides a precise and accurate current sensing solution. This board features the INA381, a high-speed current-sense amplifier with an integrated comparator from Texas Instruments. This device has selectable operating modes (transparent or latched) and detects overcurrent conditions by measuring the voltage developed across a current shunt resistor. Then it compares that voltage to a user-defined threshold limit set by the comparator reference potentiometer. The current-shunt monitor can measure differential voltage signals on common-mode voltages that vary from –0.2V to 26V, independent of the supply voltage. This Click board™ delivers higher performance to applications such as test and measurement, load and power supplies monitoring, low-side phase motor control, and many more.
