Library Description

The library contains all the necessary functions for detecting and reading the steps.

Key functions:

• uint8_t pedometer_process() - Pedometer process.
• uint32_t pedometer_getStepCounter() - Functions for get step counter.
• void pedometer_resetStepCounter(uint32_t newCnt) - Functions for reset Step counter.

Examples description

The application is composed of three sections :

• System Initialization - Sets INT pin as INPUT for detection STEP .
• Application Initialization - Initializes driver init and sets step counter on 0 .
• Application Task - It checks if a new step is detected, if detected new step - reads the current number of steps made and logs data to the USBUART.

void applicationTask()
{
    uint8_t newStep;
    uint32_t stepCounter;
    char demoText[ 50 ];
    
    newStep = pedometer_process();

    if(newStep == PEDOMETER_NEW_STEP_DETECTED)
    {
        stepCounter = pedometer_getStepCounter();
        LongWordToStr(stepCounter, demoText);
        mikrobus_logWrite(" Step Counter : ", _LOG_TEXT);
        mikrobus_logWrite(demoText, _LOG_LINE);
        
        mikrobus_logWrite("---------------------------", _LOG_LINE);
        Delay_ms( 50 );
    }
}

Other mikroE Libraries used in the example:

• Conversions Library
• UART Library

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.
