touchgfx float value

[Angle]

Hi, how can I do if I want to display the float value in touchgfx screen?

so, this is my stm32cubeide main.c which i want to display this type of data on the screen.

 

so I extern into model.cpp file. 

then I put the float value here? I got confuse since a lot of tutorial only using the uint16_t. 

Is it correct or not ? please advice me and guide me for the step or any can i refer

You should use Unicode::​snprintfFloat() function. See documentation: https://support.touchgfx.com/4.21/docs/api/classes/classtouchgfx_1_1_unicode#function-snprintffloat as well as a little discussion here: https://community.st.com/s/question/0D53W000020jQsuSAE/how-to-display-the-value-in-float-using-snprintf

Hello @Angle​ ,

@ktrofimo​ is right, the best solution for that is to use Unicode::​snprintfFloat() method with wildcards in a TextArea for example.
