Replacing array member on the fly (big LCD characters idea)

[Ioannis]

And there is Nextion displays, in many sizes, low cost, with touch and colors to do anything like that with almost zero overhead in programming.

But in either case, nice study case.

I am using the Nextion displays more and more. Not only can they display anything you like, they're easy to program, use a simple UART communication protocol (with user defined Baud rate), and because they're touch screen, they eliminate the need for buttons, knobs, and switches. You can load practically any font you want into your project, along with graphics for fancy buttons etc.

(Nuts & Volts Magazine currently has Part 4 of a 7 part article series on using the Nextion... and yes, I wrote it.)

Unfortunately, nextion displays are junk in several aspects:

1. Low display brightness, bad viewing angles, zero daylight visibility, bad contrast. Can't be compared to OLED in this field. And who needs "ease of programming" (which is very questionable), if you can't see the result?
2. Their IDE is written with left rear feet and has appropriate usability.
3. Price? Above mentioned 1602 OLED module costs $9. I'd love to have Nextion for that price.

All above is based on personal experience with nextion displays, not other's ideas or impressions.

OK, depends on what you want to do. If you want to place the LCD opposite of the sun, yes, nextion will not fit in.

In anyway, most of the user interface is well covered with these displays. As for the price, well, you can't have touch for free, right?

And the IDE is not that bad. You need to take your time, see some tutorials (there are many on-line), ask Mike if needed, he is here and very helpful and off you go.

At the end of the day, you will offer your client a more attractive device than the classic 2x16 display.

It is 21st century, and Nextion using cheapest TN+Film panels, but asking premium prices is just a funny thing They can do at least IPS, for better angles and contrast. For the touch screen, a simple glass add-on touch screen (which is used in Nextion), sized for 1602 display, costs about 30 cents in china. So you can upgrade even 1602 LCD with touch screen (I don't see any practical purpose in that, but this is possible) And by the way, topic is not about Nextion

might i ask where from , i cannot find anyone in Australia that stocks them , most tell me they are end of product life
or only have units with different chipset
ebay has no hits
crystalfontz says end of life [extortionate shipping cost]
google zip nil nothing other than the winstar site

i would get one to play with but it looks to be not worthwhile
