I got from the seller a dedicated library for UNO and ATmega2560 and I adapted to an ESP8266.
But my problem is that the software "Visual LCD Studio" (also provided by the seller) that only allows to send the 2 demos (provided) to the screen or download to the PC, but impossible to create a new project.
I contacted the manufacturer and I just received an answer.
He says that the software provided does not allow to create a new project.
So I said I did not buy a screen just to run a demo.
This screen has 2 ports: I2C for Arduino and a serial port for "Visual LCD Studio" which must compile images and commands (usable then from I2C Arduino) I have no explanation about the serial protocol, and how to compile my own project.
If you have this screen and you can use it, please share.
Thanks.
Hello,
I'd like to buy the same screen. Can you share your experience about, how were you able to manage it to use?
Have you found any arduino library for the screen?
Hello,
For this screen, I used a library that was provided to me by the seller. I modified for this to work with an ESP8266. Otherwise, use is for UNO or AtMega2560 only. For me everything is fine, I managed to use it at my convenience. The principle is that you have to create screens with a dedicated application, then compile and send in the screen memory. A port of the screen is made for that. Then I use it in wire (SCL, SDA) Interceptions are managed by a subroutine.
If you need other explanations, maybe I can help you.
Do not count too much on the manufacturer, he never responds to messages.
Hello,
5 "! I do not know this model ... I am curious and I would like to have the link to see, thank you.
For the software, it is "Visual Studio LCD" that the seller provided to me (Aliexpress) but I had obtained a more recent version by the manufacturer's site. But it was at the beginning of the existence of this screen (about 1 year) and since the manufacturer no longer puts a download link and does not respond to messages.
Hello,
Ask the vendor for software and sample programs. Otherwise you tell me if he doesn't give them and I give you what I have. But it is desirable to obtain those of the seller who will certainly be newer.
Happy holidays.
Hello,
The version offered by hundatech is an old version which has never evolved. It is full of bugs, but we have no choice, we have to deal with it! I modified the library so that it works with an ESP8266 (it works well) but impossible with an ESP32 (I did not succeed) I attach the library in zip.
Hello,
I downloaded the link, there are more recent documents (pdf) than those I have, but the software is of the same version (ver1.1.2)
The most important would have been to have a more recent version of the software (a lot of bug) and still no treatment for ESPxxxx therefore, no real evolution ... But the library that I gave works well with ESP8266, I even improved some functions. The most complicated is to understand how it works. Once acquired, it's easy to operate the screen. But there are a few things to know, because you have to play with the bugs and that's not won!
I have the 5" screen model.
I use it with arduino, and despite the fact that C or C++ is a strange language for me (I am not informatician), I manage to make it work (I spent a few hours there anyway!).
So I have followed your discussion, and unfortunately I don't have a better version of their software.
My main problem right know, is that the "number" control is not working: when I try to compile the project, I have an error.
Did you have the same problem ?
