WebThis means that a permanently faulty device will cease to be active on the bus (go into Bus Off state), but communications between other nodes can continue unhindered. If the bus media is severed, shorted or suffers from some other failure mode the ability to continue communications is dependent upon the condition and the physical interface used. WebThe CAN controller’s interface consists of 4 signal lines known as TX, RX, BUS-OFF, and CLKOUT. These four signal lines can be routed through the GPIO Matrix to GPIOs. …
