Click library

Software Support

We provide a library for the Pedometer3 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 Pedometer3 Click driver.

Standard key functions :

Example key functions :

Examples Description

The demo application displays measuring 2 accelerometers (normal accel and high pass accel), counting steps and displaying tilt positions. The sensor includes additional feature and setups that you can look up in the library.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Settings the click in the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
PEDOMETER3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
pedometer3_init( &pedometer3, &cfg );
// Default click configurations
pedometer3_default_cfg( &pedometer3 );
}

Application Task

Reads Accel and High Pass Accel X/Y/Z axis and detect Tilt Position. All data logs on the USBUART every 500 ms.

void application_task ( void )
{
static uint16_t ped_step = 0;
pedometer3_axis_t accel_axis;
pedometer3_axis_t highpass_axis;
// Task implementation.
pedometer3_get_accel_axis( &pedometer3, &accel_axis );
pedometer3_get_highpass_accel_axis( &pedometer3, &highpass_axis );
ped_step += pedometer3_get_step_counter( &pedometer3 );
log_printf( &logger, "___________ Pedometer 3 click _____________\r\n");
log_printf( &logger, "-- Accel : [ X ]: %d / [ Y ]: %d / [ Z ]: %d \r\n", accel_axis.x, accel_axis.y, accel_axis.z);
log_printf( &logger, "-- HP Accel : [ X ]: %d / [ Y ]: %d / [ Z ]: %d \r\n", highpass_axis.x, highpass_axis.y, highpass_axis.z);
log_printf( &logger, "-- Step counter : [ STEP ]: %d \r\n", ped_step);
pedometer3_get_tilt_position( &pedometer3, &tilt);
switch ( tilt.current_pos )
{
{
log_printf( &logger, "-- Current Tilt Position: [ LEFT ] \r\n" );
break;
}
{
log_printf( &logger, "-- Current Tilt Position: [ RIGHT ] \r\n" );
break;
}
{
log_printf( &logger, "-- Current Tilt Position: [ DOWN ] \r\n" );
break;
}
{
log_printf( &logger, "-- Current Tilt Position: [ UP ] \r\n" );
break;
}
{
log_printf( &logger, "-- Current Tilt Position: [ FACE DOWN ] \r\n" );
break;
}
{
log_printf( &logger, "-- Current Tilt Position: [ FACE UP ] \r\n" );
break;
}
}
Delay_ms( 400 );
}

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.

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.
