Detailed Description

CAN Bus Click Example.

Description

This library contains API for CAN Bus click board™. This example transmits/receives and processes data from CAN Bus click. The library initializes and defines the UART bus drivers to transmit or receive data.

The demo application is composed of two sections :

Application Init

Initializes driver, wake-up module, and set high-speed operation mode.

Application Task

Transmitter/Receiver task depends on uncommented code. Receiver logging each received byte to the UART for data logging, while transmitted send messages every 2 seconds.

Additional Function

• static void canbus_clear_app_buf ( void ) - Function clears memory of app_buf.
• static err_t canbus_process ( void ) - The general process of collecting presponce that a module sends.

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.
