Topic: Atmega 328 (Read 2226 times) previous topic - next topic


Hello arduino people .. :D

i will use atmega 328 and
Maybe i think true, maybe wrong but,

as i understand atmega has 1 RX and 1 TX
But i need 2 RX ..

- How can i do that ? can i change one atmega pin to RX ?

- Is there any suggestion ?

thank you
have a good arduino



There is a software serial library that should be of use to you.  http://www.arduino.cc/en/Tutorial/SoftwareSerial


Even better would be to use the NewSoftSerial library, instead. If functions more like the hardware serial function, with the ability to determine if data is available to read (which SoftwareSerial does not have).
The art of getting good answers lies in asking good questions.


Or use a 644 or mega board (2/3 hardware serial ports)



Thank you all =)

have a good day
