As I stated in another of your threads: To use sprintf for floats you need to set
Use newlib nano
Use newlib nano float formatting
Heap size 0x0200
You're right, I apologize. I'm so in over my head trying to get this project to work I miss some things.
Does the heap size have to be that exactly? Or at least 0x0200?
side note: I deeply deeply appreciate all you're help.
I did not take the time to find out the minimum value, but 0x0200 seem to be large enough for heap.
