I want to send two uint16 numbers through the serial communication. The DSP wants the header and terminator to be equal to 'S' and 'E'. The command serial does not have an option for 'header' but it has an option for defining 'terminator'.
To use the header I am writing
Now in order to send the two numbers I am using:
x = int16(1);
fwrite(obj,[x x],'int16')
I know that in each fwrite command an 'E' will be sent as well. How can I avoid this? Can I just send E at the end of the commands with another fwrite?
I am using this block to configure the DSP for receiving data.

You are right! fwrite does not automatically send terminator.

Protocol Decoder block and Protocol Encoder block might be useful in such scenarios.
