Qtserialport polling method.

Lavanya

Can any body tell me the how to implement polling method of communication for serialport using qtserialport class.

Hi,

You can take a look at the sync examples to see how to use QSerialPort in a synchronous fashion.

Be aware of the consequence of polling in a GUI application.

Hi,
That means the terminal example which implement asynchronous fashion of serial port is for interrupt method ?

Lavanya

i am bit confused with synchronous and asynchronous which is for interrupt and for polling method implementations.
can some one clarify me in regard this?

SGaist

Clarify what exactly ?

-> synchronous: you block waiting for something
-> asynchronous: you get a notification when something arrived

Lavanya

@SGaist said in Qtserialport polling method.:

you block waiting for something

Thank you SGaist.
Synchrounous=polling method of implementation.
ASynchronous=interrupt method of implementation.
This what i want to get clarified.
Thank you by your post i understand this.
