• Author : MikroE Team

• Type : I2C type

Software Support

We provide a library for the Pedometer 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 Pedometer Click driver.

Standard key functions :

• Config Object Initialization function.

  void pedometer_cfg_setup ( pedometer_cfg_t *cfg );

• Initialization function.

  PEDOMETER_RETVAL pedometer_init ( pedometer_t ctx, pedometer_cfg_t cfg );

• Click Default Configuration function.

  void pedometer_default_cfg ( pedometer_t *ctx );

Example key functions :

• Functions for get Interrupt state on the INT pin.

  uint8_t pedometer_get_interrupt_state ( pedometer_t *ctx );

• Functions for get step counter.

  uint32_t pedometer_get_step_counter ( pedometer_t *ctx );

• Generic read function.

  void pedometer_generic_read ( pedometer_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

Examples Description

This application detected steps.

The demo application is composed of two sections :

Application Init

Initializes driver init and sets step counter on 0.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pedometer_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 ---- \r\n " );

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 application_task ( void )
{
    //  Task implementation.

    uint8_t new_step;
    uint32_t s_counter;
    char demoText[ 50 ];

    new_step = pedometer_process( &pedometer );

    if ( new_step == PEDOMETER_NEW_STEP_DETECTED )
    {
        s_counter = pedometer_get_step_counter( &pedometer );
        log_printf( &logger, " Step Counter : %d \r\n ", s_counter );

        Delay_ms ( 50 );
    }

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.Pedometer

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.
