RE: [AVR-Chat] Two or more serial ports

2005-08-01 by Larry Barello

Try the MAX3110E spi uart.  Makes it simple to add as many real hardware
uarts as you need to any project.

Or, check out http://www.atmel.com/dyn/resources/prod_documents/doc2557.pdf
and just add as many mega8's as you need serial ports to your project.  It
is probably cheaper than the MAX part...

Why not use the MEGA162 to be the TWO serial ports and use 2/1wire 
communication between the 162 and the mega8/32 ?
