Dear forum members, I would like to ask a specific question in relation to the CANbus functionality on ShieldBuddy TC275 and TC375. I am using ShieldBuddy TC275 and TC375 boards and would like to start using the CAN bus on these boards for real. If possible please point to a simple example Arduino sketch that upon Uploading onto any of these two boards will demonstrate that CANbus send and receive functionality is working trouble free. Basically, Upload -> Reset -> serial port prints the CAN frames being sent and received.I have the necessary hardware support, the ShieldBuddy boards, some transceivers and other electronic components that are needed to set up the system on the breadboard. Having seen some of the Q and A posts in this section of the forum (most are historical, well past the latest revisions and updates) I conclude that it is best to ask a fresh question regarding CANbus operation on these two boards.
Thank you in advance. |

Hello sinai1,
thank you for your help, it is appreciated.
I have tried to compile on Arduino IDE, but the following errors were found (please see all the way to the bottom of the compiler output):
