In нажмите сюда sample, UART1 will be used. It is not needed. Navigate to the SerialSample source project. Make two separate copies of the app. Open two instances of Visual Studio on your PC. This will be the instance of the sample we run on the PC. Using the SerialSample App When the SerialSample app is launched on the PC, ttl apk window will open with the user interface similar to the screenshot shown below. The device ids of all the serial devices found connected ttl apk the device will be listed in the top ListBox of the SerialSample app window.
This will likely be the last device in the listbox you may кажется взломанные тв apk нами to scroll down. The app will attempt to connect and configure the selected serial device. When the app has successfully connected to the attached serial device it will display the configuration of the serial device. By default, the app configures the serial device for Baud, eight data bits, ttl apk parity bits and one stop bit no handshaking.
To send data from one device to the other connected device do the following: Choose a device to transmit from. On the transmit device, type the message to be ttl apk in the "Write Data" text box. For our example, we typed "Hello World! The app on the transmitting device will display the sent message and "bytes written successfully! If you see this, un-plug the device, plug it back in and refresh the connection or redeploy the app. SerialCommunication namespace.
The SerialDevice class will be used to enumerate, connect, read, and write to the serial devices connected to the device. For accessing the serial port, you must add посмотреть больше DeviceCapability to the Package. You can add this by opening the Package. If your appxmanifest adds ttl apk serialcommunication capability, modifying your appxmanifest with the designer will corrupt your appxmanifest the Device xml child will be lost.
Ttl apk can workaround this problem by hand editing the appxmanifest by right-clicking your appxmanifest and selecting View Code from the context menu. The following code connects and super tool скрытый видеорекордер the selected device ID and creates a SerialDevice object. FromIdAsync entry. FromMilliseconds fm радио apk serialPort. None; serialPort. One; serialPort. We do this in the sample code by creating an async read task using the DataReader object that waits on the InputStream of the SerialDevice object.
All we do is keep reading the ttl apk port in an infinite loop interrupted only when an exception is приведенная ссылка ttl apk by the cancellation token. LoadAsync ReadBufferLength. ReadString bytesRead ; status. In order to chain continuation reads from the serial port, we dynamically generate repeating tasks via "recursive" task creation - "recursively" call Listen apk 4 the end of the continuation chain.
The "recursive" call is not a true recursion. It will not больше на странице stack since every recursive is made in a new task. The "recursive" call is not true recursion. WriteString sendText. Initialize the CancellationToken object and pass that as an argument to the read task. In this sample, читать больше proceed to also refresh the list of devices ttl apk. When the user provides input, we write the bytes to the OutputStream of the SerialDevice object.
We add the ability to cancel the read task using the CancellationToken. узнать больше we close the device connection and clean up when done.
