MATLAB AppDesigner | Tutorial 7 | How to use a knob/discrete Knob

[@electricalpowerengineering532]

Great tutorials !!! In the discrete knob can we say: value = app.Knob2.Value; app.EditField_2.Value=value; It works for me just fine like the continuous one. Please keep up the good work

[@carlosecondoriochoa5962]

Yes, that way is easier.

[@umidusmanov4507]

You could display discrete knob just by making equal app.EditField_2.Value to value. There is no need to use the comparison of strings and if statement. The VALUE itself is a string which outputs the position if discrete knob

[@marcoperrotta9619]

I agree. I tried it and it works.

First of all ,I would like to say thank you for creating this tutorial.Honestly I have a hard time finding reference on making a GUI in Matlab.I tried making an Arduino project using GUIDE Matlab and is very complicated to code but AppDesigner seems very easy to use.Keep up the goodwork and hopefully you can make tutorials on how to make GUI's for Arduino using AppDesigner.

pro tip: you can watch series at flixzone. Been using them for watching lots of of movies lately.

@Steven Noah yup, I have been watching on flixzone} for since december myself =)

hi, i just want to ask something. why is bith of the callbacks for my matlab app designer not working? it kept giving me errors such as 'Error using matlab.ui.control.EditField/set.Value (line 98) 'Value' must be a character vector or a string scalar.' Please help

Hi me too

[@Ibrahima-Ba]

J'ai réussi : appli. EditField_2 a été configuré en tant que champ d’édition numérique, mais vous essayez d’y stocker un vecteur de caractère. Vous devez changer d’application. EditField_2 être un champ d’édition de texte. Devrait-il s’agir d’un champ d’édition? Voulez-vous que l’utilisateur puisse le modifier pour dire (par exemple) « Bonjour » ? Lorsque vous avez un nombre limité de valeurs autorisées et que vous souhaitez que l’utilisateur puisse choisir l’une d’entre elles, il est généralement préférable d’utiliser une zone de liste ou une dropbox.

hi u can just edit like this, value = app.FrekansKnob.Value; app.EditField.Value = string(value);

[@Ibrahima-Ba]

Hi excuse me, I have a error : Error using matlab.ui.control.internal.model.AbstractNumericComponent/set.Value (line 111) 'Value' must be a double scalar. How to correct the problem ?
