Accel 16 Click

Accel 16 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 : Luka Filipovic
  • Date : Sep 2021.
  • Type : SPI type

Software Support

Example Description

This showcases ability of the Click board to read x, y, and z axes data in different resolution, read IC temperature and also have additional functionality to read ADC data. Device also has ability to store data in internal fifo buffer.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Accel16

Example Key Functions

Application Init

Initialization of communication modules(SPI, UART) and additional interrupt pins. Reads device ID's and revision. Then configures device to work in FIFO mode or to read data from the registers, sets 2g resolution, 12.5Hz output data rate, sets interrupt 1 active low, powers on device, and calibrates temperature.

{
log_cfg_t log_cfg;
accel16_cfg_t accel16_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
accel16_cfg_setup( &accel16_cfg );
ACCEL16_MAP_MIKROBUS( accel16_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == accel16_init( &accel16, &accel16_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
accel16.application_type = ACCEL16_APPLICATION_REG;
uint8_t temp_buf[ 4 ] = { 0 };
log_printf( &logger, " > ID0: 0x%.2X\r\n > ID1: 0x%.2X\r\n > ID2: 0x%.2X\r\n > REV: 0x%.2X\r\n",

Application Task

Depending of the application mode selects example.

  • If fifo example is selected waits for the interrupt to indicate that data is ready in fifo buffer and reads number of fifo entries. Data that should be read are X, Y, Z axes and temperature.
  • If register example is selected also waits for interrupt to indicate that data is ready to read. Then reads X, Y, Z axes, temperature, and ADC data.

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.
