In this course I'll show the student how to build a Dual Controller Area Network (CAN) module using the Teensy 4.0 single board computer and program it with the free Arduino Integrated Development Environment (IDE). The schematic and breadboard bill of material are shown with complete construction instructions. The parts from Digikey can be bought for around $35 and the Teensy 4.0 headers require simple soldering skills or the student can purchase a completed CanWiser module.

Part 1 is the Introduction where an overview of the course is presented.

Part 2 is building the breadboard hardware

Part 3 is getting the software from the free Arduino Integrated Development Environment to the Teensy addon and then programming the Dual CAN breadboard with a simple checkout program

Part 4 is sending and receiving CAN messages using 2 of the Teensy 4.0 onboard CAN interfaces.

Part 5 on building a CAN data logger to capture CAN messages and store them in the on-board SSD card on the Teensy 4.1 is included.

The completed Dual CAN Module can be used by the student to further their understanding and knowledge of the Controller Area Network. Using the Teensy modules with the Arduino IDE is a great and inexpensive way to explore embedded systems programming.
