Accel 25 click

Accel 25 Click is a compact add-on board that contains an acceleration sensor. This board features the MXC4005XC, a 12-bit three-axis thermal accelerometer from MEMSIC. It allows selectable full-scale acceleration measurements of ±2g, ±4g, or ±8g in three axes with a compatible I2C serial interface with 400KHz fast mode operation.

  • Author : Stefan Ilic
  • Date : Feb 2023.
  • Type : I2C type

Software Support

We provide a library for the Accel 25 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 Accel 25 Click driver.

Example Description

This example demonstrates the use of Accel 25 click board by reading and displaying

accel data (X, Y, and Z axis) as well as temperature measurements on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
accel25_cfg_t accel25_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
accel25_cfg_setup( &accel25_cfg );
ACCEL25_MAP_MIKROBUS( accel25_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == accel25_init( &accel25, &accel25_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( ACCEL25_ERROR == accel25_default_cfg ( &accel25 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads and displays the accel data (X, Y, and Z axis) as well as temperature measurements

on the USB UART every 100ms approximately.

void application_task ( void )
{
accel25_data_t meas_data;
// Wait for data ready indication
{
if ( ACCEL25_OK == accel25_read_data ( &accel25, &meas_data ) )
{
log_printf( &logger, " X: %.3f g\r\n", meas_data.x );
log_printf( &logger, " Y: %.3f g\r\n", meas_data.y );
log_printf( &logger, " Z: %.3f g\r\n", meas_data.z );
log_printf( &logger, " Temperature: %.2f degC\r\n", meas_data.temperature );
}
Delay_ms ( 100 );
}
}

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.Accel25

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.
