Welcome in the forum!

   

No need to present your email address here, I suggest you to delete it.

   

To print floats use the sprintf() function which will convert a float into a string. Some prerequisites:

   

Update to PSoC Creator 3.0 from Cypress website

   

In the view of the .cydwr file, "System" tab: set the "heap size" to 0x0200

   

In Project -> Build Settings -> Linker set use newlib-nano float formatting to "true"

   

in your main.c add a #include <stdio.h>

       

Happy coding

Here is a program that shows how to use the sprintf() commands.  It is setup for Psoc 5lp and is running on PSoC Creator  3.3 CP2 (3.3.0.7343).

Here is the program using a CY8Ckit-049-42xx.

Up date your PSOC Creator to the latest version as it makes support easier.

should i update Psoc3.0 became to 3.3 CP2 ? After that archive02 file will work on Psoc3.3 CP2  ?  So Do i dont need other bootloadable.hex file from using now ?

[rola_264706]

You need recompile the SCB_bootloader.cwrk file  after you update to Psoc Creator 3.3 CP2 that way you will have the correct files for the  bootloadable  dependencies . You should also install all of the kit files you intend to use.  Make sure your other files are updated also such as the PsocProgrammer is updated also.
