Relay Click 3 is a dual relay Click board, featuring two single-pole double-throw relays which can be operated by output pins of the host microcontroller (MCU). It offers an elegant and easy solution for controlling a wide range of power applications.
We provide a library for the Relay3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Relay3 Click driver.
Config Object Initialization function.
void relay3_cfg_setup ( relay3_cfg_t *cfg );
Initialization function.
RELAY3_RETVAL relay3_init ( relay3_t ctx, relay3_cfg_t cfg );
This function turns on either the 1st or the 2nd relay on the Click.
void relay3_relay_on ( uint8_t relay );
This function turns off either the 1st or the 2nd relay on the Click.
relay3_relay_off ( uint8_t relay );
This example starts off with the initialization and configuration of the Click and logger modules and later on showcases how to turn specified relays ON/OFF using the output pins.
The demo application is composed of two sections :
This function initialises and configures the logger and Click modules.
void application_init ( )
{
log_cfg_t log_cfg;
relay3_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 ----");
// Click initialization.
relay3_cfg_setup( &cfg );
RELAY3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
relay3_init( &relay3, &cfg );
}
This function turns on the 1st and the 2nd relay and then turns them both off.
void application_task ( )
{
case_1( );
Delay_ms ( 1000 );
case_2( );
Delay_ms ( 1000 );
case_3( );
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
