Hello!
I am new to using teensy and need to communicate over canbus between several teensys for a project. For the sake of simplicity I am starting by just trying to send a short message from one teensy to another. I am currently using the following CAN bus chips: https://copperhilltech.com/can-bus-mini-breakout-board/. I have found good resources for wiring, but am struggling to work through the code. I am trying to use the flexcan library and have found example code to receive a message but am struggling as to how to send a message. Does anyone have any good resources/tutorials I should look into?
Additionally, I have access to either Teensy 3.2 or 4.0s. Someone told me that a new feature of the Teensy 4.0 was that you did not need an additional can bus break out board to send/receive messages. Is that accurate? I could not find documentation to support that claim.
Any help is much appreciated
