Library Description

Library provides functions for controlling en pin, and getting int pin state.

Key functions:

• uint8_t motion3_get_int ( void ) - Function for getting int pin state
• void motion3_set_en_pin ( uint8_t state ) - Function for setting en pin state
   

Examples description

The application is composed of three sections :

• System Initialization - Initialization of pins
• Application Initialization - Maps pins and enables device
• Application Task - Waiting for motion to be detected

void application_task ( )
{
    uint8_t int_status;

    int_status = motion3_get_int();

    if ( int_status != MOTION3_INTERRUPT_NOT_DETECT )
    {
        mikrobus_logWrite( "Motion detected", _LOG_LINE );
        while ( int_status != MOTION3_INTERRUPT_NOT_DETECT )
        {
            int_status = motion3_get_int();
        }
        mikrobus_logWrite( "Motion wait", _LOG_LINE );
    }
}

Other mikroE Libraries used in the example:

• UART

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.
