Click library

Software Support

We provide a library for the Opto3 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 Opto3 Click driver.

Standard key functions :

Example key functions :

Examples Description

Opto 3 click to be used in applications that require reinforced galvanic isolation for both their input and output stages.

The demo application is composed of two sections :

Application Init

Initializes GPIO interface.

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.
opto3_cfg_setup( &cfg );
OPTO3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
opto3_init( &opto3, &cfg );
log_printf( &logger, "** Opto 3 is initialized **\r\n" );
}

Application Task

Switches ON or switches OFF the both outputs depending on the states of the inputs, respectively.

void application_task ( void )
{
OPTO3_STATE state_in1;
OPTO3_STATE state_in2;
OPTO3_SWITCH state_out1;
OPTO3_SWITCH state_out2;
state_in1 = opto3_get_in1( &opto3 );
state_in2 = opto3_get_in2( &opto3 );
state_out1 = state_in1 ^ 1;
state_out2 = state_in2 ^ 1;
log_printf( &logger, "** Opto 3 out1 is**\r\n" );
opto3_set_out1( &opto3, state_out1 );
log_printf( &logger, "** Opto 3 out2 is **\r\n" );
opto3_set_out2( &opto3, state_out2 );
}

Note

Input state is active low, and output state is active high.

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.
