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.
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.
This library contains API for Timer Relay Click driver.
timerrelay_cfg_setup
Config Object Initialization function.
void timerrelay_cfg_setup ( timerrelay_cfg_t *cfg );
timerrelay_init
Initialization function.
err_t timerrelay_init ( timerrelay_t *ctx, timerrelay_cfg_t *cfg );
timerrelay_default_cfg
Click Default Configuration function.
err_t timerrelay_default_cfg ( timerrelay_t *ctx );
timerrelay_set_wiper_pos
Timer Relay set wiper position function.
err_t timerrelay_set_wiper_pos ( timerrelay_t *ctx, uint8_t wiper_pos );
timerrelay_activate_reset
Timer Relay reset timer function.
void timerrelay_activate_reset ( timerrelay_t *ctx );
timerrelay_activate_trigger
Timer Relay activate trigger function.
void timerrelay_activate_trigger ( timerrelay_t *ctx );
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 :
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; /**< Logger config object. */
timerrelay_cfg_t timerrelay_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
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 " );
}
This example is activating the trigger every 4 seconds activating the relay timer.
void application_task ( void )
{
timerrelay_activate_trigger( &timerrelay );
log_printf( &logger, " Trigger activated. \r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
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.

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.
