Click library

Software Support

We provide a library for the Accel12 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 Accel12 Click driver.

Standard key functions :

Example key functions :

Examples Description

This application allows acceleration measurement in three perpendicular axes.

The demo application is composed of two sections :

Application Init

Initialization driver init and configuration Accel measuremen and Tap detection interrupt

void application_init ( void )
{
log_cfg_t log_cfg;
uint8_t temp;
// 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.
ACCEL12_MAP_MIKROBUS( cfg, MIKROBUS_1 );
accel12_init( &accel12, &cfg );
accel12_default_cfg( &accel12 );
log_printf( &logger, "--- Start measurement --- \r\n" );
}

Application Task

Reads the acceleration data in 3 axis and detects the tap on the axes. All data logs on the USBUART every 1.5sec.

void application_task ( void )
{
int16_t X_Axis;
int16_t Y_Axis;
int16_t Z_Axis;
uint8_t tap;
/* Accelerometer measurement */
accel12_get_axis_data( &accel12, &X_Axis, &Y_Axis, &Z_Axis );
log_printf( &logger, " X axis : %d \r\n", X_Axis );
log_printf( &logger, " Y axis : %d \r\n", Y_Axis );
log_printf( &logger, " Z axis : %d \r\n", Z_Axis );
/* TAP interrupt */
tap = accel12_get_tap_detection( &accel12 );
switch ( tap )
{
case 1:
{
log_printf( &logger, " X positive \r\n" );
break;
}
case 2:
{
log_printf( &logger, " Y positive \r\n" );
break;
}
case 3:
{
log_printf( &logger, " Z positive \r\n" );
break;
}
case 4:
{
log_printf( &logger, " X negative \r\n" );
break;
}
case 5:
{
log_printf( &logger, " Y negative \r\n" );
break;
}
case 6:
{
log_printf( &logger, " Z negative \r\n" );
break;
}
}
log_printf( &logger, " -------------------------------- \r\n" );
Delay_ms( 1500 );
}

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.
