display in stm cube ide for project of nanoedge studio ia

[IsmailYangui]

Hello everyone, I am working on a project using nanoedge studio ia in rating N, I want to check my project with cube ide, I can make a view with tera term or other tool, which shows the result corresponding to my database. I used stm32L475vgt6; The problem is that there is also no display with a simple code that says printf(hello World)

Hello Ismail,

I didn't understand your question.

Can you explain me what is the "println(hello World")" you are talking about?

You can use screenshot if you need to.

Have a good day,

Julian

after i finished all steps of nanoedge . now i want to do this project in stm cube ide . i want the result displays in tera term . but there is no result appear in tera term so i make a simple code to testing . but no result also . now i  want to make a led to light up when the result is diabetes and light off when non_diabetes .. to undrsatnd me . the dataset i used in nanoedge is a dataset for daibetes . so it's 1 if daibetes else 0
