Accel 2 Click

Accel 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : I2C/SPI type

Software Support

Example Description

This application is three-axis accelerometer which embeds.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Accel2

Example Key Functions

  • accel2_cfg_setup Config Object Initialization function.
void accel2_cfg_setup ( accel2_cfg_t *cfg );
  • accel2_init Initialization function.
err_t accel2_init ( accel2_t *ctx, accel2_cfg_t *cfg );
  • accel2_generic_write Generic write function.
void accel2_generic_write ( accel2_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );
  • accel2_check_id Check Accel 2 ID.
uint8_t accel2_check_id ( accel2_t *ctx );
  • accel2_read_xaxis Function read X axis.
uint16_t accel2_read_xaxis ( accel2_t *ctx );
  • accel2_read_yaxis Function read Y axis.
uint16_t accel2_read_yaxis ( accel2_t *ctx );

Application Init

Initialization device. Check sensor ID and initialize Accel 2 Click.

void application_init ( void )
{
   log_cfg_t log_cfg;
   accel2_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 ----" );

   accel2_cfg_setup( &cfg );
   ACCEL2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
   accel2_init( &accel2, &cfg );
}

Application Task

This is a example which demonstrates the use of Accel 2 Click board. Measured coordinates (X,Y,Z) are being sent to the UART where you can track their changes.

void application_task ( void )
{
   int16_t value_x;
   int16_t value_y;
   int16_t value_z;
   uint8_t txt_x[ 15 ];
   uint8_t txt_y[ 15 ];
   uint8_t txt_z[ 15 ];

   value_x = accel2_read_xaxis( &accel2 );
   value_y = accel2_read_yaxis( &accel2 );
   value_z = accel2_read_zaxis( &accel2 );

   log_printf( &logger, "Axis X: %d\r\n", txt_x );

   log_printf( &logger, "Axis Y: %d\r\n", txt_y );

   log_printf( &logger, "Axis Z: %d\r\n", txt_z );
   
   log_printf( &logger, "-------------------------------" );

   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
