Library Description
The library covers all the necessary functions to control Signal Relay click board. Signal Relay click
communicates with the target board through the AN, RST, CS and PWM line. This library
offers functions for turning on or off any and every of the four relays on this click board.
Key functions:
void signalrelay_relayOneOff();- Function turns relay 1 off.The application is composed of three sections:
void applicationTask()
{
mikrobus_logWrite( " Relay One Turn On ", _LOG_LINE );
signalrelay_relayOneOn();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( " Relay Two Turn On ", _LOG_LINE );
signalrelay_relayTwoOn();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( "Relay Three Turn On", _LOG_LINE );
signalrelay_relayThreeOn();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( " Relay Four Turn On", _LOG_LINE );
signalrelay_relayFourOn();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( " Relay One Turn Off", _LOG_LINE );
signalrelay_relayOneOff();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( " Relay Two Turn Off", _LOG_LINE );
signalrelay_relayTwoOff();
Delay_ms( 1000 );
mikrobus_logWrite( "-------------------", _LOG_LINE );
mikrobus_logWrite( "Relay Three Turn Off", _LOG_LINE );
signalrelay_relayThreeOff();
Delay_ms( 1000 );
mikrobus_logWrite( "--------------------", _LOG_LINE );
mikrobus_logWrite( " Relay Four Turn Off", _LOG_LINE );
signalrelay_relayFourOff();
Delay_ms( 1000 );
mikrobus_logWrite( "--------------------", _LOG_LINE );
}

UARTAdditional 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
