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 :
relay6_cfg_setup
Config Object Initialization function.
void relay6_cfg_setup(relay6_cfg_t *cfg)
Relay 6 configuration object setup function.
Relay 6 Click configuration object.
Definition: relay6.h:151
relay6_init
Initialization function.
err_t relay6_init(relay6_t *ctx, relay6_cfg_t *cfg)
Relay 6 initialization function.
Relay 6 Click context object.
Definition: relay6.h:134
relay6_default_cfg
Click Default Configuration function.
err_t relay6_default_cfg(relay6_t *ctx)
Relay 6 default configuration function.
Example key functions :
relay6_reset_port_expander
Relay 6 reset port expander function.
void relay6_reset_port_expander(relay6_t *ctx)
Relay 6 reset port expander function.
relay6_port_expander_write
Relay 6 port expander write register function.
err_t relay6_port_expander_write(relay6_t *ctx, uint8_t reg, uint8_t data_in)
Relay 6 port expander write register function.
relay6_set_relay
Relay 6 set relay state function.
err_t relay6_set_relay(relay6_t *ctx, uint8_t on_relay, uint8_t off_relay)
Relay 6 set relay state function.
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.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
if ( I2C_MASTER_ERROR ==
relay6_init( &relay6, &relay6_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
#define RELAY6_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.
Definition: relay6.h:121
void application_init(void)
Definition: main.c:27
@ RELAY6_ERROR
Definition: relay6.h:169
Application Task
Switches all relays state every second and displays the state on the USB UART.
{
uint8_t relay_data;
log_printf( &logger, " Turning on only Relay 1 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay_data <<= 1;
Delay_ms( 1000 );
log_printf( &logger, " Turning on only Relay 2 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay_data <<= 1;
Delay_ms( 1000 );
log_printf( &logger, " Turning on only Relay 3 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
relay_data <<= 1;
Delay_ms( 1000 );
log_printf( &logger, " Turning on only Relay 4 \r\n" );
log_printf( &logger, " = = = = = = = = = = = = = \r\n" );
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.
