debug_printf not printing floating point numbers

peter_fenn — Wed, 03 Jun 2015 23:47:49 GMT

In bare-metal KDS3 + KSDK1.2 project using debug_printf, all the remedial steps described in previous posts were tried but none of these fixed the issue.
Finally got float numbers to print correctly by uncommenting the #define PRINTF_FLOAT_ENABLE 1 in the print_scan.h file under the SDK\platform\utilities\src folder!

- What is the correct method (ie.from KDS IDE settings) to get this to work?

Hi Peter,

Check this post that towards the bottom shows how to add in #define in the Properties of the project.

If you try it let us know if this is successful or not.

printf() with float values

Regards,

David

True. Other methods do not work to me and only Peter's method does. KDS3.0+KSDK1.3, MQX light.
