the modem interface below is very reasonable. The four methods declared by this interface are indeed the functions of the modem. Public interface modem {public void dial (string PNO); // connect public void hangup (); // disconnect public void send (char C ); // send public char Recv (); // receive} However, this interface shows two responsibilities. The first is connection management, and the second is data communication. Do these two duties need to be separated? This depends on how the applic

If debug is required, what is the purpose of the tested code? Do not test it at the beginning. debug it directly. There are two reasons why the te

The following areTop five: Bloated class:The reason why the class is bloated is that developers lack the most basic coding principle, namely the "single Responsibility Principle" (SRP. These classes tend to become very bloated because different methods that lack Association in func

1: single responsibility principle (SRP ): An excellent System Design emphasizes the relationship between modules with low coupling and high cohesion. In object-oriented design, this rule is also applicable. Therefore, the first design principle of object-oriented design is: single Responsibility Principle (SRP, single responsibility principle ). A single responsibility emphasizes the separation of duti

Even if you don't believe in the full DDD approach, you should also be very careful about class structure and naming. Each class is a clue that you leave to yourself and others, and it helps you rebuild your mental model when you return in the future. variable, parameter, and method namingtry to avoid common variables and method naming.

). OTG devices are fully compliant with the USB2.0 standard and provide a host of detection capabilities that support the Host Orders Protocol (HNP) and the dialog request Protocol (SRP). In OTG, the initial host device is called a device, and the peripheral is called a B device. The initial role can be determined by how the cable is connected. Figure 1 shows that the default host is determined with the 5th ID pin, and the dual-use device uses the new

To achieve such a feature, there is a new concept in OTG-dual-function devices (Drd:dual-roledevice). 1 DRD can meet the following characteristics:Have a certain USB host capability and provide a list of 1 peripherals;Full speed operation (or fast operation) as a peripheralSupports full speed operation (low or fast) as a master control machineSupport for Host Negotiation

One DRD can meet the following requirements: ● Has certain USB Host capabilities and provides a list of peripherals; ● Full-speed operations (or quick operations) can be performed as peripherals ); ● As the master machine, it can support full speed operations (low speed or fast) ● Supports host negotiation protocol (HNP) and Session Request Protocol (
