    Serial Read/Write on RS-232

    FredA

      Can the 3.5 mm RS-232 port on the Galileo board be used for input/output using the Serial.read and Serial.write statements in the Arduino IDE?

       

      If so, what is the port number.

          Not without tinkering. The default setup doesn't use that one. You can find the mappings in a thread called "Serial ports" by EJP.

            Thank you AlexT

             

            OK,   So my plan A will not work.  Plan B would be to use an RS-232 shield that gets its RX and TX from pins 0 and 1.

             

            Do pins 0 and 1 on the Galileo conflict with the USB as they do on some other Arduino boards.

             

            I am a little disappointed.  The third paragraph of the Galileo product brief says that the RS-232 port is one of the features that "expands the native usage and capabilities beyond the Arduino shield ecosystem."  That would seem to me that the RS-232 port is supported.

              Well, I think the phrase is correct - native capabilities in this case is direct access to Linux console and UEFI shell, which indeed expand potential usages beyond shields (and for shields there's UART @ pin 0 & 1)
