 ### Programming Tutorial
 
-Here's a small example how the Open1722 library can be used to build and parse IEEE 1722 PDUs. First we define a C struct for a custom IEEE 1722 packet that can be used to transport a CAN, a LIN and a Flexray message. The frame begins with a Time-synchronous Control Format (TSCF) header. After the TSCF header a list of AVTP Control Format (ACF) messages follows. The first ACF message is a ACF CAN message which consists of ACF CAN header as well as a payload section to carry a 2Byte CAN frame. Similar than with the CAN message another ACF messages for LIN is added.

First define a C struct for a custom IEEE 1722 packet that can be used to transport a CAN and a LIN message. The frame begins with a Time-synchronous Control Format (TSCF) header. Alternatively a Non-Timesynchronous Control Format (NTSCF) header could be used. After the TSCF header a list of AVTP Control Format (ACF) messages follows. The first ACF message is a ACF CAN message which consists of ACF CAN header as well as a payload section to carry a 2Byte CAN frame.
