do not forget that having a SW UART, in effect, kill the processor when it is running.

I mentioned in the FAQ, in the first sentence ("even if they work properly they consume a lot of instruction cycles").

Erik Malund said:
The only "no UART UART" I have seen, that has any resemblance of working as a UART processor consumption wise, is one I saw somewhere (I forgot where, maybe someone else can give a link) was one based on two PCA counters.

http://www.intel.com/design/mc...270531.htm ? It's in the FAQ...

Erik said:
Why not just use a processor with two UARTs, why use kludges when solutions are available?

In the FAQ, the first recommended alternative.
