5. Synchronous api

Synchronous api example

Remember to check the examplesync module for a complete example using the synchronous api

Use

UsbSerial also allows to use it in a synchronous way.

public boolean syncOpen();
public int syncWrite(byte[] buffer, int timeout) // Blocking operation
public int syncRead(byte[] buffer, int timeout) // Blocking operation
public void syncClose();

Flow control is also performed in the same way that the Asynchronous api.
