Wireless remote control uses high-frequency radio waves to control the model. For example, the 6-channel 2.4 GHz Remote Control of wfly, a set of more than 200 pieces, with automatic frequency hopping anti-interference capability, theoretically, we can allow hundreds of people to remotely control their models at the same site without interfering with each other. In addition, the remote control distance is also quite advantageous. The power of the 2.4 GHz remote control system is only less than 1

In the establishment of the project, the start Task StartTask () started the task MyTask (), also set up a message queue, and then send a message queue, send out their own deleted themselves, the receiver has been able to receive data??? Why??? Because our message queue is not emptied, there is always data in the message queue, of course, in the execution of MyTask's task, mytask inside has this sentence waiting for message queue ss=osqpend (STR_Q,0

1. Application description of the telephone interceptor When we enter the phone number and make a call, the system will issue an ordered broadcast (Action = "android. intent. action. new_outgoing_call "), which is expected to be sent to the broadcast receiver of the phone dial application. However, we can set a higher priority interceptor broadcast receiver (Android: Priority =" 1000 "), this allows the

We recommend that you do not forget some basic parameters of the infrared receiver diode. 1. Dark Current: When the infrared receiving diode is in the terminated state, there is still a current called dark current. This dark current has a slight relationship with the reverse voltage, but it is highly correlated with the temperature. As shown in: 2. the infrared receiving diode is vulnerable to interference. It will respond to a certain range of

Broadcast receiver in Android can be used to listen for broadcast events. Before using broadcast, you must either use code or register in Androidmanifest.xml. The following example implements using SMS to trigger an example in androidgraphics2dtutorial.

Android source code Analysis--BroadcastBroadcasting is a way of delivering messages between components. The implementation of broadcasting mechanism is based on the binder interprocess communication.Binder interprocess communication and broadcast differences: In binder, the client component and service component must first obtain a proxy object for the service before the client component has to know the presence of the service component beforehand. The broadcast sender is not aware of the presen
