Isn't it just another clocked serial interface? No, it's an asynchronous serial interface; half duplex over one wire. Andy Neil said:
And not a particularly fast one, at that? That depends. I know of companies that run it at > 200kbps. Andy Neil said:
If so, shouldn't be hard at all! Well, the basic hardware interface isn't difficult at all. Just tie Rx and Tx together and you're good to go. Implementing the protocol stack (T=1 in particular) is a different matter, though. Rob. |
