About rc car systems usage and details

Every rc car has a receiver. When looking to manage the device, you will find it very simple. Moreover, you can totally capture all frames that reach the DMX connector. The display shows the word "OFF" until the user selects a channel using the keypad matrix. In addition, the decimal points can be quite precise to ensure functionality!

The OS as extended machine

In this facet of the personality of the SO, the outstanding feature is to simplify the programmer the details of the operation of rc car devices connected to the system. This feature is also evident in applications where the OS is not used. A programmer can use these functions without knowing that the data is put on pins or read, change multiple records in the uC. It is said that these functions are an abstraction of the process I / S in port. This is good because it helps developers to develop solutions more quickly and with less likelihood of mistakes and that if the function is well written it is unlikely to fail.

The extended machine function is to provide the rc car programmer an "interface" through which resources are used the system without having to delve too deeply into the details of the operation of its various components. This interface the OS provides the programmer or user, commonly known as system calls or APIs (Application Programmer Interface).

However, this view of the operating system is very applicable to our environment, in the sense that today are classified as system calls, because in our world everything is small in capacity and creating a powerful machine consumes resources extended usually will not have. So in this case the machine is limited to some extended function calls and use OS libraries so far have used regularly.

The OS as resource manager

In this case the OS, acts as a steward of our resources. The advantage of having someone to manage resources efficiently is that the OS provides the user with a set of rules for sharing and making use of available resources effectively and efficiently.

An example of resource management is the use in a system with no OS, the programmer has to be very aware of the implementation of your rc car system because certain conditions may be temporary in the execution of some functions have to be fulfilled. In our case it is usual for us to break the coconut handling interruptions, delays making, changing and checking counters flags.
