also a point. The third point is that there is no transistor to zoom in. It can also be used. Put the theoretical discussion here for the time being. Continue the new experiment.
The software experiment is to develop an APP to launch data.
The first step is to record the audio output by the remote control genie. The hardware connection uses a public earphone plug to record the key waveform output by the remote
"closed" AndroidIn the beginning, Android is really open source, but now you say that the closed source estimates are no one to oppose.Many people say Android, "Google's own site, as closed as Microsoft's website." It is open source, all under the GPL license to open source. "Lock OEM ManufacturerBy using the app's upgrade to close the source, Google's control on the mobile side stems mainly from app group
electronic products, users are far from it. Users are not able to directly touch the screen and other ways to enter. So Android soft keyboard mode is really not good enough input interactive mode. For the English Department of the country. The input of this TV is OK, just need to be entered directly through the external keyboard, but for a language like Chinese such as the need for conversion, it is troubl
devices can be controlled.According to the principle of remote control to know 38kHz sine wave signal required. the method of how to generate sine waves is found in Playing an arbitrary tone with Android .The test found that it could not output 38kHz, the maximum is only 20KHz. In turn, test "remote control Genie" Output frequency is also 20KHz, then use 20KHz s
products, users from it is a distance, users can not directly touch the screen and other ways to input, so the Android soft keyboard is not good enough input interactive mode. For the English-speaking countries, this TV input is OK to solve, simply through the external keyboard input directly, but for similar to the Chinese language needs to be converted, the problem. This is because the
realization of developing an APP to launch data. The first step is to record the audio output from the Remote Control Wizard. The hardware connection is to record the key waveform output by the remote control genie using a grandfather's headphone plug. Put it in your phone to play audio to send an infrared signal to the TV. Validation passed.2.DIY SoftwareAfter
completion of the invocation of the service lookup, find the call function, after obtaining the WSDL, we can call it, the process of the call, passed the object is a soap wrapped object ...How to call WebService is the main ....The webservice call process is actually very simple ... We just need to know the parameters to be passed when calling the function, and the URL of the function to make the call of the remote method easy ...Calling webservice n
