## Code Examples

The following code examples needs to be uploaded to each of the UNO R4 WiFi boards, one will send a message, one will receive it. These examples are available in the Renesas core, and using the Arduino IDE, you can access them by navigating to **File > Examples > Arduino_CAN > CANWrite/CANRead**

The library used is built in to the core, so no need to install the library if you have the core installed.
The library used is built into the core, so no need to install the library if you have the core installed.

To initialize the library, use `CAN.begin(CanBitRate::BR_250k)`, where a CAN bit rate is specified. Choose between:
