Explanation Of CAN Bus

Modern car today like an a small computer where everything is connected each other in the same network.  It have a few network normally used in car like a Controller area network(CAN), Local Interconnect network(LIN), Media Oriented System Transport(MOST) and FlexRay. The most used is CAN Bus . CAN BUS allow ECU communicate each other without host computer. Before, in Old car, the number of ECU is less because low demand on the technology. Today, with current technology, a modern Car have a more than 70 ECU. How it looks like if everything is connected using old way? Hard wire? That the reason in mid-1980, Bosch design CAN Bus to reduce costs and complexity inside the vehicle. CONTROLLER AREA NETWORK(CAN)        CAN is a serial communication bus where allow ECU in car communicate each other robustly with maximum bit rate of 1Mb/s for high speed. It is a mist suitable for systems where a small amount information needs to be exchange. Instead of automo...

Understanding of Embedded System Concept

An embedded system is a controller with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today according to Wikipedia . I am not going to share about definition and etc.. What i am going to share is how it work??πŸ˜ƒπŸ˜ƒ The three main component is Processor, RAM and Memory..Why? and What is the roles of this component? Imagine... πŸ‘·πŸ‘‰ Processor πŸ“πŸ‘‰ Table as RAM πŸ“•πŸ‘‰ Cabinet as Memory You(Processor) processing data at your table(RAM). Then if you need something, get it from Cabinet(Memory) and put into the table and process it. As simple as That!😁 In automotive industry nowadays, for instance, most of the car using radio which is not a Norma radio but intelligent radio which is connected to each ECU in the car. This radio is most like a mini computer where it ...
