Click library

  • Author : Nenad Filipovic
  • Date : Nov 2023.
  • Type : SPI type

Software Support

We provide a library for the Rotary B 2 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 Rotary B 2 Click driver.

Example Description

This library contains the API for the Rotary B 2 Click driver to control LEDs states and a rotary encoder position readings.

The demo application is composed of two sections :

Application Init

Initialization of SPI module and log UART. After the driver init, the app executes a default configuration and turn off all LEDs.

void application_init ( void )
{
log_cfg_t log_cfg;
rotaryb2_cfg_t rotaryb2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
rotaryb2_cfg_setup( &rotaryb2_cfg );
ROTARYB2_MAP_MIKROBUS( rotaryb2_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == rotaryb2_init( &rotaryb2, &rotaryb2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( ROTARYB2_ERROR == rotaryb2_default_cfg ( &rotaryb2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

This example demonstrates the use of the Rotary B 2 Click boardâ„¢. The demo example shows the functionality of a rotary encoder used to control LEDs.

void application_task ( void )
{
if ( ROTARYB2_OK == rotaryb2_set_led_data( &rotaryb2, led_data ) )
{
rotaryb2_switch_detection( );
rotaryb2_encoder_mechanism( );
}
}

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.RotaryB2

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.
