Robostix SNAP

From GumstixDocsWiki

S.N.A.P. is Scalable Node Address Protocol

It is an easily implemented protocol that will support multiple nodes (robostix) on an asynchronous serial interface. Here is a comparison of various serial interfaces.

The robostix code is here. The master node is implemented in Python.

This example can be run with RS232 levels between UART0 on the robostix and any computer that can run Python (Windows, Linux host, Gumstix).
