Arduino IDE Compiled SoftwareSerialExample failed

[victory460]

 I tried to use

‘ Arduino15 \ packages \ Digilent \ hardware \ pic32 \ 1.0.3 \ libraries \ SoftwareSerial\examples\SoftwareSerialExample‘
Soft serial port to achieve a send and receive function, but it is wrong:

which is why?How to solve it?

Hi @victory460,

I think (but don't know for certain) that the issue is that the source code for the SoftwareSerial library (not originally designed by Digilent) doesn't support the MZ chip that is used on the WiFIRE boards since I was able to successfully compile the software serial example for all of the other PIC32MX based Digilent boards.

I have asked another Digilent engineer to confirm this and to learn what sort of changes would need to be made to get this example in the Digilent core working for the WiFIRE board.

Thanks,
JColvin

Hi @victory460,

James was correct, it is an issue in the source code for the SoftwareSerial library. The PIC32MZEFG100 does not have an SIDL bit in the CNCON register like the older chips. You can get around this by commenting out those lines in SoftwareSerial.cpp for now. I have added an ifndef line to fix this in the Digilent Core v1.0.4 which i just uploaded.

Hope this helps!

Thank you very much for your answer, I followed your approach, and it succeeded.

My goal is to add another one serial communication to OpenScope MZ then I tried to use a soft serial port in the OpenScope MZ firmware, but it compiled failed.

exit status 255

I know this question is repeated definition Serial, but I do not know how to modify it to add a serial port.

Please help me to add one serial communication to OpenScope MZ .Thank you very much.
