Keylock click

Keylock click carries a processed sealed key lock mechanism that can be set in three different positions. The click is designed to run on either 3.3V or 5V power supply.

Click library

Software Support

We provide a library for the Keylock 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Keylock Click driver.

Standard key functions :

Example key functions :

Examples Description

This application monitors key position in its lock mechanism.

The demo application is composed of two sections :

Application Init

Initialization driver enables GPIO and also writes log.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info(&logger, "---- Application Init ----");
// Click initialization.
KEYLOCK_MAP_MIKROBUS( cfg, MIKROBUS_1 );
keylock_init( &keylock, &cfg );
Delay_ms( 100 );
log_printf( &logger, "--------------- \r\n" );
log_printf( &logger, " Keylock Click \r\n" );
log_printf( &logger, "--------------- \r\n" );
}

Application Task

Detects the position in which the key currently is.

Results are being sent to the Terminal, where you can track changes.

void application_task ( void )
{
uint8_t new_state;
uint8_t old_state = 0;
new_state = keylock_get_position( &keylock );
if ( old_state != new_state )
{
if ( new_state == KEYLOCK_KEY_POS_1 )
{
log_printf( &logger, " Position ONE \r\n" );
}
else if ( new_state == KEYLOCK_KEY_POS_2 )
{
log_printf( &logger, " Position TWO \r\n" );
}
else if ( new_state == KEYLOCK_KEY_POS_3 )
{
log_printf( &logger, " Position THREE \r\n" );
}
else
{
log_printf( &logger, " ERROR!!! \r\n" );
}
old_state = new_state;
log_printf( &logger, "---------------- \r\n" );
}
Delay_ms( 500 );
}

Note

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
