I have to confess that when I design a standalone microcontroller
project, the interface almost always is RS232. Most uCs have UART
functionality with data rates up to at least 250Kbps. I don't have
to fool with complicated protocols and the interface is very useful
for debugging. MAX232s or their equivalent are cheap and easy to
RS232 means that I can hook it to just about anything.
I've got a pile of USB->RS232 adapters for those crippled systems
that can speak only USB of some flavor.
