I am using an arduino board to get flow reading from a honeywell zephyr flow meter. When I implement my code I just get a consistent -2.5 value. The honeywell talks in hexadecimal and so I need to convert that to decimal so I have usable information I have attached my code for you to see. Not sure what is going on with the program. Any help will be great.
