robo copter

Preface The message passing process from the physical port of flight control to the application layer is sorted by combining the Mavlink message previously added.By the passing of the whole frame in the comb again; here combined with Rover to narrate, May and copter some difference, start first ~ libraries Here needs to explain, regarding the Mavlink the agreement and the generation part, here does not have the detailed description, after specially w

and disadvantages. The first advantage is to avoid using virtual methods to slightly increase the execution speed. The second point is to clearly know which methods will be overloaded. Let's look at a class about aircraft description. Suppose we have a base class that describes airplanes. Now, we need to complete an aircraft control system with a global function fly, which is responsible for sending the plane to take off. Then, we only need to do this: Using system; Class plane { Public Virtual

attacker can directly access the. ipa package of the original application and copy its art interface for use. For example, there is almost no difference between Touch Scan Pro on the right and TouchScan on the left, except that the color is changed from green to blue. A similar problem occurred last month. After the release of an e-book reader named Classics, its UI was completely copied by another application e-book. In some cases, the copied application is the free version of the copied paid

20080610 The helicopter was finally found today, it's more than ten days after the accident of the copter. the result was so depressed. including a clew of five military personnel and 14 quake victims were all found dead. what a pity! Just had gotten though the earthquake, but encountered this unfortunate things. I cocould do nothing to make things better. eeverything I can do is to pray for them. Please, be safe !. The miserable truth no one cocould

. Regular 3-node (or more-node) Vsan clusters still use traditional methods, witness component or scattered across all hosts in the cluster.Application ScenariosThe problem comes, Witness appliance is also on a host, and this host can not be a 2-node Vsan in a cluster of one, that is not to say or need 3 host? Since there are 3 hosts, then why bother to specialize, directly build a regular 3-node Vsan cluster can not?Well, that's a good question to ask, but the 2-node Vsan scenario is not the sa

Ubuntu has revealed to the outside that their newest idea of Iot is to make Linux the core of making Iot more intelligent and scalable. SnappyUbuntuCore is the latest platform for smart devices. It promises to run the same software stored locally or on the cloud. Obviously, the biggest benefit of the latter is that users can avoid frequent regular upgrades. For Ubuntu, the biggest advantage of the platform over competitors is its current user base. For example, ErleRobo Ubuntu has revealed to th

minimalist style. 　Design Thumb Size Click object for Game Application The question we cannot speculate is whether the user uses your index finger to manipulate more or more with your thumb. So, for this, we have to do a very careful research, and then set a reasonable target size. However, if your application is a game, most users will use the thumb. That's why in many game applications, the size of some controls is usually as big as the thumb, so that users can hold their hands more securel
