Timer Relay click

Timer Relay Click is a compact add-on board that allows you to control the load with a timer. This board features the NE5555, a precision timer from Diodes Incorporated. It is a precision timing circuit capable of producing accurate time delays in a monostable mode of operation.

Click library

  • Author : Stefan Ilic
  • Date : Jun 2023.
  • Type : SPI type

Software Support

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

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of the Timer Relay Click board by

setting the relay timer to 2 seconds ON time, then holding it OFF for 2 more seconds.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration,

then setting the ON time to 2 seconds.

void application_init ( void )
{
log_cfg_t log_cfg;
timerrelay_cfg_t timerrelay_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
timerrelay_cfg_setup( &timerrelay_cfg );
TIMERRELAY_MAP_MIKROBUS( timerrelay_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == timerrelay_init( &timerrelay, &timerrelay_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( TIMERRELAY_ERROR == timerrelay_default_cfg ( &timerrelay ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
if ( TIMERRELAY_ERROR == timerrelay_set_delay( &timerrelay, 2 ) )
{
log_error( &logger, " Value configuration." );
for ( ; ; );
}
timerrelay_activate_reset( &timerrelay );
log_info( &logger, " Application Task " );
}

Application Task

This example is activating the trigger every 4 seconds activating the relay timer.

void application_task ( void )
{
log_printf( &logger, " Trigger activated. \r\n" );
Delay_ms( 4000 );
}

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.TimerRelay

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.
