HardwareSerial conflicting declaration #42
Comments

HI JosepM,
I didn't see a solution to the problem in the thread you mentioned. Did you?
I'm sorry but I never used a Due before so I'm unfamiliar with this problem.
But I guess whatever solution you find, you can apply it to the controlino
sketch as well.
If you do, please consider making a pull-request with the changes you made.
And btw, please have a look at the develop-v2 thread on Github. I started
implementing a second much-better version of Instrumentino and I'd be
really happy if other interested people would like to join me in its
development.
Thanks,
Joel

However, for an Arduino Uno it just works fine and it compiles correctly.
Googling the problem I found this github thread
<mrstig/arduino-netbeans#6>. In the last
comment they mention that those device specific flags may be the origin of
the problem, but I don't know if that is applicable to your code.
Have you ever had this issue before?
Thank you in advanced!

Hello, I have also used instrumentino with the arduino due and I had to make some changes. extern HardwareSerial Serial; and extern HardwareSerial Serial1; On the other hand in order to use SPI comunication. I have replaced: SPI.transfer(strtol(argV[i], NULL, 10)); Best regards, |
