- CIC Prefix : RELAY3
- Author : Aleksandar Paunovic
- Verison : 1.0.0
- Date : Nov 2018.
We provide a library for the Relay_3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
Library contains functoins for turning on/off relays 1 and 2. Library contains functions for turning on/off relays 1 and 2 after a defined period of time.
Key functions :
void relay3_relayOn( uint8_t relay_ )
- Turns selected relay onvoid relay3_relayOff( uint8_t relay_ )
- Turns selected relay offvoid relay3_onDelay( uint8_t relay_, uint8_t units_, uint16_t time_ )
- Turns selected relay on after a defined period of time in selected units of timevoid relay3_offDelay( uint8_t relay_, uint8_t units_, uint16_t time_ )
- Turns selected relay off after a defined period of time in selected units of time
Examples Description
The application is composed of three sections :
- System Initialization - Initializes LOG functionality, initializes RST and CS pins as OUTPUTs
- Application Initialization - Initializes GPIO driver
- Application Task - Activates relays 1 and/or 2 based on user input
void applicationTask( )
{
dataReady = UART_Rdy_Ptr( );
if (dataReady != 0)
{
receivedData = UART_Rd_Ptr( );
switch (receivedData)
{
case '1' :
{
relay3_case1( );
break;
}
case '2' :
{
relay3_case2( );
break;
}
case '3' :
{
relay3_case3( );
break;
}
default :
{
mikrobus_logWrite( "wrong command", _LOG_LINE );
break;
}
}
}
}
Additional Functions
- void relay3_case1( ) - Turns relay 1 on/off
- void relay3_case2( ) - Turns relay 2 on/off
- void relay3_case3( ) - Turns relays on/off
The full application code, and ready to use projects can be found on our LibStock page.

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.
