Relay 6 click

Relay 6 Click is a compact add-on board for precise load control and monitoring applications. This board features four 9913-05-20TRs, a reed relay from Coto Technology, well-known for its ultra-miniature SMD design, which offers the smallest footprint in the market. These four relays each have four load connection terminals and blue LED indicators that signal the operational status, ensuring clear and immediate feedback.

Click library

  • Author : Stefan Ilic
  • Date : Nov 2023.
  • Type : I2C type

Software Support

We provide a library for the Relay 6 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 Relay 6 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of Relay 6 click board by toggling the relays state.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

void application_init ( void )
{
log_cfg_t log_cfg;
relay6_cfg_t relay6_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
relay6_cfg_setup( &relay6_cfg );
RELAY6_MAP_MIKROBUS( relay6_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == relay6_init( &relay6, &relay6_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( RELAY6_ERROR == relay6_default_cfg ( &relay6 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Switches all relays state every second and displays the state on the USB UART.

void application_task ( void )
{
uint8_t relay_data;
relay_data = RELAY6_RELAY1_PIN;
log_printf( &logger, " Turning on only Relay 1 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay6_set_relay( &relay6, relay_data, ~relay_data );
relay_data <<= 1;
Delay_ms ( 1000 );
log_printf( &logger, " Turning on only Relay 2 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay6_set_relay( &relay6, relay_data, ~relay_data );
relay_data <<= 1;
Delay_ms ( 1000 );
log_printf( &logger, " Turning on only Relay 3 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay6_set_relay( &relay6, relay_data, ~relay_data );
relay_data <<= 1;
Delay_ms ( 1000 );
log_printf( &logger, " Turning on only Relay 4 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay6_set_relay( &relay6, relay_data, ~relay_data );
relay_data <<= 1;
Delay_ms ( 1000 );
}

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.Relay6

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.
