Three important concepts in the Linux device model are bus, device, and driver. That is, bus, device, driver, and in fact, the kernel defines some data structures such as struct bus_type, struct device, and struct device_driver. These three important data structures come from one place, include/linux/device.h. We know that there are many types of buses, … Read more
Mark as Favorite Read Good Articles Daily As a PCB design engineer, it is essential to possess knowledge about high-speed signals. High-speed signals are typically found in various parallel buses and serial buses. Understanding what a bus is will help you determine its speed and start routing. Bus A bus is a shared physical pathway … Read more
As the automobile industry develops, the number of electrical devices in vehicles is increasing. For each additional electrical device, two power lines must be added. Simultaneously, each electrical device requires two additional switch wires. The rapid increase in electrical devices in vehicles has led to a corresponding rise in switch wires. This increase in electrical … Read more
Source:Automotive Chassis Home Requirements for Adding Termination Resistors According to ISO11898-2 regulations on the value of termination resistors, a 120Ω termination resistor must be connected at both ends of the bus, totaling 60Ω on the bus, while intermediate nodes do not require termination resistors, as shown in Figure 1. Figure 1 Termination Resistor Effects of … Read more
Bus control, as the name suggests, refers to a control system where many devices are set up on a single bus circuit. As shown in the figure below, all smoke exhaust outlets in the same smoke compartment can be controlled by a single bus control line. A button on the bus control panel can simultaneously … Read more
