Compile error

[Mark]

Hi Martyn,

My parts have all finally arrived and I’m starting to build. It’s been a couple of years since I programmed Arduinos (4 actually). I installed the 1.6.3 IDE, downloaded your sketch and the required lib etc.

When I try to compile I get an error

parseNewdata.ino: In function ‘void parseNewData()’:
parseNewdata.ino:63:37: error: invalid conversion from ‘const char*’ to ‘char’ [-fpermissive]
Error compiling.

The line says
receivedChars[0] = “”;

That looks fine to me – right kind of quotes anyways.

Any idea?

Thanks!

Actually I think I solved it.

You were assigning receivedChars[0] to null as ‘slash 0’

I changed it to read

receivedChars[0] = 0;

and it now compiles.

I haven’t run it yet as I’ve yet to build but I think that should be fine, no?

What version of the IDE are you using?
I think this comes up with the newer IDEs.

I installed 1.6.3 because that’s what you said you used – I figured it would make life easier.

Also because my nano is an older one – the longer board with the larger chip and the 12v power supply jack. I figured I’d have a better chance of the older IDE working with an older nano.

Hi Mark,

thanks for reporting back.

This has been reported before but I couldn’t duplicate the issue so assumed it was a change in the compiler or compiler settings with newer IDEs.

Just thought it may actually be the wrong kind of quotes. Maybe it needs single quotes but a zero should work fine.
