This appendix describes the recipe to be followed in order to implement a new protocol. A new protocol can be executed by the host computer or the electronic boards. In both cases, the host algorithm has to be coded and only in the last case, the PICs firmware has to be recoded. In the first section of this appendix we show how to modify the host algorithm. In the second one, we show how to code the PICs. It is not necessary to understand the whole host algorithm (see the section Host Software in Appendix C) to be able to code a new protocol.
