TEXT PROGRESS Negative Values

[Ofaro.1]

Hi,

I'm trying to display the temperature values ranging from -40 to +40 on TEXT PROGRESS in TouchGFX designer. Unfortunately, the values range only starts from 0.

Can anyone help me with this? I'll be very grateful.

Hi,

You cannot directly work with negative values with a Text Progress widget. What I suggest to do is create your own Text progress by using a Box Progress widget instead and adding text over it with a textArea widget. That way you can display whatever text you need. For the box progress widget, if you need to go from -40 to 40degrees, then I would set the minimal value to 0 and the maximum value to 81 (-40 to 40 but dont forget the 0 degree value).

Hi Romain,

Thanks for your kind guidance. This is a great suggestion but I want to make one thing more clearer that how come the TextArea widget will update the text i.e. when the temperature will change for e.g. 15 C to 18 C ?

I also understand that the box Progress widget will update according to the values but I want to display temperature values if this makes sense.

I will be very grateful for your feedback.

Hi,

You need to update the text Area yourself through code to change the value when relevant. I'll attach a project of what I had in mind.

Hi Romain,

One more question regarding TouchGFX, when I import an image in touch gfx, it generates the correctly but in STM32 IDE, this error comes "undefined reference to `image_icon_hourglass' ".

TouchGFX is generating the code fine.

Your kind comments will be very helpful.

Hi,

Where is this error faced ? Can you run on target from TouchGFX or do you just generate code from it ?

What you could try to do within STM32CubeIDE is to clean and re build. Try to delete the generated folder in the tree view of your project in CubeIDE.

Hi Romain,

Really appreciate your response.

It's been fixed, just needed to enable the automatically generate makefiles.

Thanks
