Hello !

I'm trying before buy Flowcode 5 for AVR free edition.
I will need for my next project square root function on ATMEGA2560 MCU.

This MCU isn't available in the free edition but I think the problem is not here.

Impossible to compile. Is it a problem on the free edition or on the commercial licence too ?

How to solve this problem ?
Thank you for your help

Hello

I tried with my Flowcode 5.5 for PIC licence and it compile well. I don't know if the computation works in the real life but it works in simulation.
So I think it is a problem with the AVR release.

Hello,

No there does seem to be an issue with compilation even on the pro license. I will investigate and see if it is a quick fix.

Adding this to the defines section of the supplementary code should resolve the issue.

#define float32_sqrt sqrt

I'll see if I can find a more elegant fix to get this bug wrapped up.
