Library Description

The library offers an option to control the state of relays.

Key functions:

void relay_relay2Control( uint8_t pinState ) - Controls the Relay 2 pin.

void relay_relay1Control( uint8_t pinState ) - Controls the Relay 1 pin.

Examples Description:

The application is composed of three sections:

• System Initialization - Sets pin directions.
• Application Initialization - Initializes driver.
• Application Task - Turns relays on and off.

void applicationTask()
{
relay_relay2Control ( 1 );
relay_relay1Control( 1 );
mikrobus_logWrite("Relays turned on", _LOG_LINE);

Delay_ms(1000);

relay_relay2Control ( 0 );
relay_relay1Control( 0 );
mikrobus_logWrite("Relays turned off", _LOG_LINE);

Delay_ms(1000);
}

Other mikroE Libraries used in the example:

• UART

Additional notes and information

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.
