IR 2 Click Board

We provide a library for the IR 2 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.

Library Description

This library contains API for the IR 2 Click Board™ driver.

Key functions

• ir2_get_out_pin This function returns the OUT pin logic state.

• ir2_nec_send_data This function sends an address and data bytes using NEC protocol.

• ir2_nec_read_data This function reads an address and data bytes by using NEC protocol.

Example Description

This example demonstrates the use of the IR 2 Click Board™ by showing the communication between the two click boards configured as a receiver and transmitter using the NEC protocol.

void application_task ( void ) 
 { 
     #ifdef IR2_TRANSMITTER_MODE 
         log_printf( &logger, " Sending message." ); 

         for ( uint8_t cnt = 0; cnt < sizeof ( IR2_DATA ); cnt++ ) 
         { 
             ir2_nec_send_data ( &ir2, IR2_ADDRESS, IR2_DATA[ cnt ] ); 
             log_printf( &logger, "." ); 
         } 

         log_printf( &logger, "rn Message has been sent! rn" ); 
         log_printf( &logger, "- - - - - - - - - - - - rn" ); 
         Delay_ms( 500 ); 
     #else 
         uint8_t address; 
         uint8_t rx_data; 

         if ( IR2_OK == ir2_nec_read_data ( &ir2, &address, &rx_data ) ) 
         { 
             log_printf( &logger, "Address: 0x%.2X, Data: %crn", ( uint16_t ) address, rx_data ); 
         } 
     #endif 
 }

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

Other MikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.IR2

Additional Notes and Information

Depending on the development board you are using, you may need a 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.

MIKROSDK

The IR 2 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
