Click library
- Author : Stefan Ilic
- Date : Sep 2023.
- Type : UART type
Software Support
We provide a library for the Opto 7 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 Opto 7 Click driver.
Standard key functions :
opto7_cfg_setup
Config Object Initialization function.
void opto7_cfg_setup(opto7_cfg_t *cfg)
Opto 7 configuration object setup function.
Opto 7 Click configuration object.
Definition: opto7.h:134
opto7_init
Initialization function.
err_t opto7_init(opto7_t *ctx, opto7_cfg_t *cfg)
Opto 7 initialization function.
Opto 7 Click context object.
Definition: opto7.h:111
Example key functions :
opto7_generic_write
Opto 7 data writing function.
err_t opto7_generic_write(opto7_t *ctx, uint8_t *data_in, uint16_t len)
Opto 7 data writing function.
opto7_set_gp1_pin
Opto 7 set GP1 pin function.
void opto7_set_gp1_pin(opto7_t *ctx, uint8_t pin_state)
Opto 7 set GP1 pin function.
opto7_get_gp2_pin
Opto 7 get GP2 pin function.
uint8_t opto7_get_gp2_pin(opto7_t *ctx)
Opto 7 get GP2 pin function.
Example Description
This example demonstrates the use of Opto 7 click board by processing
the incoming data and displaying them on the USB UART.
The demo application is composed of two sections :
Application Init
Initialization of UART LOG and GPIO pin, and UART drivers.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
if ( UART_ERROR ==
opto7_init( &opto7, &opto7_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
#define OPTO7_MAP_MIKROBUS(cfg, mikrobus)
MikroBUS pin mapping.
Definition: opto7.h:86
void application_init(void)
Definition: main.c:78
Application Task
This example is made of two parts: GPIO Example - The output pin is toggled every 5 seconds and input pin state is being tracked. UART Example - Device assigned as transmitter is sending message and receiver is reading it and displaying it on USB UART.
{
#if ( DEMO_EXAMPLE == EXAMPLE_GPIO )
log_printf( &logger, " GP1 pin state HIGH \r\n" );
{
log_printf( &logger, " GP2 pin state HIGH \r\n" );
}
else
{
log_printf( &logger, " GP2 pin state LOW \r\n" );
}
log_printf( &logger, "- - - - - - - - - - - -\r\n" );
Delay_ms( 5000 );
log_printf( &logger, " GP1 pin state LOW \r\n" );
{
log_printf( &logger, " GP2 pin state HIGH \r\n" );
}
else
{
log_printf( &logger, " GP2 pin state LOW \r\n" );
}
log_printf( &logger, "- - - - - - - - - - - -\r\n" );

#else
#if defined TRANSMITTER
log_printf( &logger, " Message sent! \r\n" );
Delay_ms( 2000 );
#else
if (
OPTO7_OK == opto7_process( &opto7 ) )
{
opto7_log_app_buf( );
opto7_clear_app_buf( );
}
#endif
#endif

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.Opto7
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.
