Detailed Description

Opto 7 Click 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.

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.

Additional Function

static void opto7_clear_app_buf ( void )
static void opto7_log_app_buf ( void )
static err_t opto7_process ( opto7_t *ctx )

< 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 LOG_MAP_USB_UART macro definition for detailed explanation.
