I'm trying to get sprintf working with SDK 17.1.
Basically, I'm struggling getting this simply use-case to work.
char buf[32];
sprintf(buf, "%.3f", 3,5);
I'm not able to find a flag that enables this support. Any assistant would be greatly appreciated.
Hi,
Which compiler/IDE are you using?
In Segger Embedded Studio, there is a project option to enable float support for printf:
You also likely need to change your "float" from "3,5" to "3.5", comma is used to separate different parameters.
I verified that the float in sprintf works in UART peripheral example in SES, with the above option set to "float".
Best regards,
Jørgen
