 		 #129907 - use Atmels
Responding to: ???'s previous message
Most Atmel 8051 contain the PCA, which make it easy to generate 5 half UARTs (RXD or TXD).

For receive simple enable the capture function and then the compare function to scan the 8 data bits.

For transmit simple use the set/clear pin on compare function.

Also use the highest priority (level 3) for the PCA, so no other interrupts are able to destroy the bit timing.

      Yes , you can build your own software port.            01/01/70 00:00

   Have you considered 8052?            01/01/70 00:00      
      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      
            why on earth do that            01/01/70 00:00

                  yechhh ... ATMEL (eewwww...)            01/01/70 00:00      
                  8051 -> AVR: not easy !!!            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      
               architectures            01/01/70 00:00      
                  There are many ways of defining "best"            01/01/70 00:00
