Library Description

Library provides functions for communicating and fully control device. There are specific functions for reading data from slots A and B, setting interrupt mask and reseting device.

Key functions:

• uint8_t smoke2_get_int_pin ( void ) - Get state of int pin
• uint16_t smoke2_read_data ( uint8_t reg ) - Generic function for reading data from registar
• void smoke2_write_data ( uint8_t reg, uint16_t tx_data ) - Generic function for writing bit state

Examples description

The application is composed of three sections :

• System Initialization - Initialization of communication modules and additional pins
• Application Initialization - Mapping pins and configures device for measurement
• Application Task - Example shows module working depending on example mode

void application_task ( )
{
    if ( EXAMPLE_MODE_SMOKE == example_mode )
    {
        smoke_example(  );
    }
    else
    {
        proximity_example(  );
    }
}

Additional Functions :

• void smoke_example () - Example checks if sensor data is gone over thershold set
• void proximity_example () - Reads sensor data and logs it

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• SPI
• I2C
• UART
• Conversions

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.
