In this chapter, we discovered the CAN bus and how we can connect our embedded kits together in order to exchange data between them. We presented the CAN utilities we can use to quickly get access to the CAN bus, and we discussed a bit regarding the possibility to do a transceiver-less connection for a short-range communication.
In the next chapter, we will look at a group of devices that was rarely used in the past on an embedded computer. However, since the past few days, these devices are becoming one of the most important peripherals an embedded system must have. They are the multimedia devices.
