C library PSoC3 to PSoC5

[ScEn_283436]

Hi,

   

I have recently switched from Creator 3.0 - PSoC3 to Creator 3.3 SP2 - PSoC5. Have been having issues getting the libraries to function as they did previously in 3.0. I have checked the migration guide and there is no mention of the C libraries. First I had a problem with math.h and found an app-note on that regarding the build settings->linker->general. Is there a similar thing you have to do for stdio.h? The sprintf function doesn't do anything. Also, is there a guide for setting all this up?

   

Thanks,

   

Nick

To use sprintf() for floats:

   

    
• Increase the heap to at least 0x0200
    
• Use newlib nano
    
• Use newlib nano float formatting
