content: Hi,I have been looking at various 3.5" to 4.5" intelligent/programmable/HMI displays that have a serial interface to connect to my other custom electronics.I have come across various manufacturers but the most common ones seem to be Nextion vs Stone.Which manufacturer you would reccomend... Nextion or Stone or other ones?My priorities for this project are reliability and ability to make a circular progress bar like the one attached. The latter seems to be a trivial thing but after downloading the programming software of various manufacturers that does not seem so. They all have a gauge widget but it has the hand (like a clock) and I cannot use that type of gauge for aesthetic reasons and also because at the centre of the circle I have to display data.Am I missing something? Perhaps the way you would construct such gauge/circular-progress-bar?Thank you as always!

content: you have Dwin too hmi based displaysIve played a bit with themI find good resemblances between Stone and DwinI would say nextion is another kind of hmi, not the same software, not the same mentality

content: Thank you coromonadalixI had a look at Dwin and yes it does look like another option.In what way is the Nextion different from Stone and Dwin?Why would you choose any one over the other two?Thank you

content: I have used Nextion for two different projects.Models NX4827T0043 and NX4832T035I have about 4 of each model left over after the prototype fail...If the freight was not too expensive I would send them to you for nothing.The issues:Their UI design software is a dog with fleas. (Nextion Editor)Documentation is poor.The screen refresh rate is very slow.Very limited collection of UI elements. Certainly nothing like the widget you are looking for. (At the time I was using it.)It has been a couple of years since that project and they may have improved since then.They would have to improve a lot.YMMV

content: Thank you Mr.BThey might not be suitable for the projects I posted about but they might come handy for other 1-off personal projects where just basic functionality is enough.How much is the posting to the UK? If it is not too much I might take up your offer and pay for the shipping.Thank you!

content: Even arduino lcd tft screens can be good too, it depend of your needs,I could say hmi display are not what we could call intelligent in nature, they depend of the main board (brain / intelligent side) to do their workDwin, Stone are like visual interface, you program buttons functions and visual / graphical look(s) if i may saySome nextion are more powerful nowNew Dwin hmi display with the t5 and newest technology are more powerful too, some of them are almost like an android tablet lollOnce again it will depend of your needsYou have adruinos world, raspi ... and many devices on the market i would search for the most available "community / shared experiences / projects / librairies "One thing i hated, some hmi displays brand / forums are poorly maintained for some of them, chineeses forums seems more elaborated, and have more ressources than their english "translated" counterparts ... even for softwares releases, docs, examples, tips ...That's a thing you have to consider for long term projectsmy 2 cents
