 		 #129958 - it's quite easy
Responding to: ???'s previous message
I think if you really want two serial ports then i think you should witch to atmega128

Erik Malund said:
why on earth do that, there are plenty of '51 derivatives with two UATS
even though I am sure it is a misspell, redoing a job from '51 to atmega would require a lot of time or a witch :)

While it might be a lot of time, it's actually quite easy.
I had rewritten several '51 asm projects into AVR asm and found out it is quite straighforward. For one longer task I even started to write a 51->AVR "compiler" but gave up as the rewrite was faster and easier...
The point is, that the AVRs have more resources (if you are allowed to choose a big enough type), relatively similar architecture (OK this is arguable), and even if most of the '51 opcodes translate into a bunch of AVR opcodes, it has ample processing power and plenty of code space and RAM to allow this.

I hope I will not be ex(s)pelled from 8052.com for this heresy.

      No 1 on Jan's List!            01/01/70 00:00      
      no problem in using 805x            01/01/70 00:00      
         do so, but first ...            01/01/70 00:00

                                    Fair point - so back to OP            01/01/70 00:00      
         Maybe one uArt is enough...            01/01/70 00:00      
   use Atmels            01/01/70 00:00      
      why use Atmel?            01/01/70 00:00      
         Maybe other architecture            01/01/70 00:00

                     good discussion            01/01/70 00:00      
                        How can you do this            01/01/70 00:00      
                           hand shaking            01/01/70 00:00      
                              no need of handshaking signals            01/01/70 00:00      
                                 you are right            01/01/70 00:00      
                              Not necessarily            01/01/70 00:00      
                     I confirm that            01/01/70 00:00      
         it all depends on what he can both get and afford            01/01/70 00:00      
            The architecture doesn't really matter            01/01/70 00:00
