IR 2 Click is a compact add-on board representing a compact and easy solution for adding infrared (IR) remote control to your design. This board features the TSMP58138, a miniaturized sensor for receiving the modulated signal of QEE113 IR emitting diode from Vishay Semiconductors. This IR sensor module consists of a photodetector, pre-amplifier, and automatic gain control to surpass ambient noise with signals transmitted to it in the near-infrared range with a wavelength of 940nm. It also communicates with the target MCU via selectable GPIO lines.

IR 2 Click is a compact add-on board representing a compact and easy solution for adding infrared (IR) remote control to your design. This board features the TSMP58138, a miniaturized sensor for receiving the modulated signal of QEE113 IR emitting diode from Vishay Semiconductors. This IR sensor module consists of a photodetector, pre-amplifier, and automatic gain control to surpass ambient noise with signals transmitted to it in the near-infrared range with a wavelength of 940nm. It also communicates with the target MCU via selectable GPIO lines.
We provide a library for the IR 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.
This library contains API for IR 2 Click driver.
ir2_cfg_setup
Config Object Initialization function.
void ir2_cfg_setup ( ir2_cfg_t *cfg );
ir2_init
Initialization function.
err_t ir2_init ( ir2_t *ctx, ir2_cfg_t *cfg );
ir2_get_out_pin
This function returns the OUT pin logic state.
uint8_t ir2_get_out_pin ( ir2_t *ctx );
ir2_nec_send_data
This function sends an address and data bytes using NEC protocol.
void ir2_nec_send_data ( ir2_t *ctx, uint8_t address, uint8_t data_in );
ir2_nec_read_data
This function reads an address and data bytes by using NEC protocol.
err_t ir2_nec_read_data ( ir2_t *ctx, uint8_t *address, uint8_t *data_out );
This example demonstrates the use of an IR 2 Click board by showing the communication between the two Click boards configured as a receiver and transmitter using the NEC protocol.
The demo application is composed of two sections :
Initializes the driver and logger and displays the selected application mode.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
ir2_cfg_t ir2_cfg; /**< Click config object. */
/**
* 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 " );
// Click initialization.
ir2_cfg_setup( &ir2_cfg );
IR2_MAP_MIKROBUS( ir2_cfg, MIKROBUS_1 );
if ( PWM_ERROR == ir2_init( &ir2, &ir2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, "- - - - - - - - - - - - \r\n" );
#ifdef IR2_TRANSMITTER_MODE
log_printf( &logger, "- Transmitter mode - \r\n" );
#else
log_printf( &logger, "- Receiver mode - \r\n" );
#endif
log_printf( &logger, "- - - - - - - - - - - - \r\n" );
log_info( &logger, " Application Task " );
}
Depending on the selected mode, it sends a desired message using NEC protocol or reads all the received data and displays them on the USB UART.
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, "\r\n Message has been sent! \r\n" );
log_printf( &logger, "- - - - - - - - - - - - \r\n" );
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: %c\r\n", ( uint16_t ) address, rx_data );
}
#endif
}

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.
