Opto 2 Click is a galvanic isolator Click board™, used to provide an optical isolation of sensitive microcontroller (MCU) pins, when operated by external signals.
We provide a library for the Opto2 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.
This library contains API for Opto2 Click driver.
Config Object Initialization function.
void opto2_cfg_setup ( opto2_cfg_t *cfg );
Initialization function.
OPTO2_RETVAL opto2_init ( opto2_t ctx, opto2_cfg_t cfg );
OUT1 Check function.
uint8_t opto2_check_out1 ( opto2_t *ctx );
OUT2 Check function.
uint8_t opto2_check_out2 ( opto2_t *ctx );
OUT3 Check function.
uint8_t opto2_check_out3 ( opto2_t *ctx );
This application used to provide an optical isolation of sensitive microcontroller.
The demo application is composed of two sections :
Initializes device selects the outputs (OUT1 - OUT4) which state be checked.
void application_init ( void )
{
log_cfg_t log_cfg;
opto2_cfg_t cfg;
/**
* 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.

Performs the check procedure for selected outputs and logs the states from that outputs on USB UART. Repeat the check procedure every 2 seconds.

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.
