Help for double variable...

[Wolfgang Kos]

Hello,
I have a Problem with double variable from external C-Code.
The external C-Code is insert with include.

The double variable for speed like this:

extern double speed_external;
the value is like 0.0

Then I insert C-Code in flowcode like this why i will see the speed on display:

C-Code.jpg (24.31 KiB) Viewed 5301 times

and I becomes this error:

Error.jpg (32.28 KiB) Viewed 5301 times

What can I do?
When I delete this C-Code, all is good, other function on the external Code will function good.

Thank you for all Infos.

Wolfgang

Hi Wolfgang,

Please can you post a program that demonstrates this and we will investigate for you. It's usually down to something minor.

Hell Benj,

thank you for you answer, I will look for code, is very difficult many files

I can read the variable now, I make it in external code when I will see the variable like this Value=5.5 I only see Value=5
Is think the variable is bad defined from me.

How I must defined from typ double variable in Flowcode ???

Hi Wolfgang,

It depends on which micro you're using but a double is often defined as a single precision float.

How are you printing out the value?

H Benj,

I solved the problem, I find in Flowcode this code:

float2int() and FloatToString$()

very good...
