Hardware development generally refers to the hardware development of electronic products. The research and development of a kind of visible electronic products, such as mobile phones, mice, keyboards, and stereos are all hardware. Hardware development is a series of researches carried out in these areas. Hardware development is generally divided into: schematic design, circuit diagram design, PCB board design, test board production, functional testing, stability testing, single-chip design, small batch production, formal market or formal use and other steps.
What happens to the Node ID in the CAN bus?
In principle, two nodes are not allowed to have the same ID segment in a CAN-bus network, but what if the two nodes have the same ID segment?
Before the experiment, we must first have a clear un
