Accel 17 click

Accel 17 Click is a compact add-on board that contains an acceleration sensor. This board features the MXC62320MP, a low-power digital output dual-axis accelerometer fabricated on a standard, submicron CMOS process from MEMSIC.

Click library

  • Author : Luka Filipovic
  • Date : Sep 2021.
  • Type : I2C type

Software Support

We provide a library for the Accel17 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Accel17 Click driver.

Standard key functions :

Example key functions :

Example Description

This example showcases ability of the device to read

x, y axis orientation.

The demo application is composed of two sections :

Application Init

Initialization of communication modules(I2C, UART), and

configures device.

void application_init ( void )
{
log_cfg_t log_cfg;
accel17_cfg_t accel17_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
accel17_cfg_setup( &accel17_cfg );
ACCEL17_MAP_MIKROBUS( accel17_cfg, MIKROBUS_1 );
err_t init_flag = accel17_init( &accel17, &accel17_cfg );
if ( I2C_MASTER_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
accel17_default_cfg ( &accel17 );
Delay_ms( 1000 );
log_info( &logger, " Application Task " );
}

Application Task

Reads axis data and calculates it and logs result every 300ms.

void application_task ( void )
{
accel17_get_axes_data ( &accel17, &axes );
log_printf( &logger, " > X[degree]: %.2f\r\n > Y[degree]: %.2f\r\n", axes.x, axes.y );
log_printf( &logger, "*********************************\r\n" );
Delay_ms( 300 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Accel17

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. UART terminal is available in all MikroElektronika compilers.
