The communication protocol is defined by means of a set of frames that both transmitter and receiver can understand.
For instance and example of frame can be like in the following figure.

With comStudio is possible to customize each frames defined in the communication protocol. This can be done in the Frame customization widget. It is used for both Commands and Receive frames. In this way comStudio can decode, or build upon request, each frame defined in the protocol.

In the Frame customization widget is possible to change the frame name.
The structure of the frame can be modified through the sub-frame editing.
Finally it is possible to view the frame data in different format: Hexadecimal, ASCII (Text) or Decimal.
In the Frame customization widget it is possible also to enable the automatic CRC computation and set the linked receive frame or the linked command.
