SoftwareSerial error:

Question

Please help me with this library "Softwareserial". The basic sketch does not work. Please look the errors:

    C:\Program Files (x86)\Arduino\libraries\SoftwareSerial\SoftwareSerial.cpp:128:2: error: #error This version of SoftwareSerial supports only 20, 16 and 8MHz processors

PLEASE HELP ME!

Welcome. This is a Q&A system and not a dump and answer forum. Also if you provide more info and about the board used and also bother formatting the code. The answer will be as simple as you have probably tried to use the library with a board that is no compatible. — RSM

This is impossible to answer without your code, and without knowing what board you are compiling for. Please read How do I ask a good question?. — Nick Gammon

You're trying to use the AVR SoftwareSerial library with an ARM based board. It won't work. Ever.

There should be no need to use SoftwareSerial - the SAMD chips have multiple UART channels - just use one of those.

Thanks, I understand what you mean. BTW one more question. What about Bluetooth which connecting to Arduino board. I have this line in my code: SoftwareSerial bluetooth(1,0); In this case, i use the softwareserial library, how then to be?
