Thanks! I don't mind getting a response as I can neglect it, so I haven't searched for it. Read the manual of the display, and it will be described there if it is possible to turn it off.
After using the DWIN software for a while i feel it is a long way from a complete package. The software needs a few for functions to become ready for mainstream use. It needs at least the ability to simply define a background color for each screen and control. Using a dedicated image for each background and control should be an option. It would be nice if there was an option to specify a color gradient for things like a slide bar. It should not be a big issue even if the color is converted into the required format in background.
Hi! I think it is rather complete, but some functions are just really cumbersome. But I guess this is due to the fact that they based the whole logic on changing and manipulating values under SP/VP addresses. Also, most of the dynamically added things' colours can be changed by manipulating the values under the SP address of the control, if I remember correctly. However, I never came across a color gradient for a slide bar. I don't know if it is possible, but maybe there's a workaround for it.
Hi, I watch the video and I'd like to say things which I tried to understand. In the menu part, we give key value for all button but the problem is Enter button. When I choose enter for the enter button, it didn't send the values to serial terminal, but when I changed enter to return, it fixed the problem. Did you do the same things or did I miss some part?
Nice tutorial Mr. Scientist! Now a question, if you have an opinion with that. Looks like a litle bit complex to share info between the Arduino PLC and the hmi Screen.... If we choose a Raspberry for our projects (Linux) with Python, for example, or even pure javaScript we can share and control data from plc - screen superEsay way... Then.. What am I missing? Why is that hard with arduino and what's the benefit ? fast proces? cheap systems? Ok.. Arduino don't need any OS to operate... yes BUT! thanks anyway for the super-interesant video! Im gona use it on my next project.
Hi and thanks! I respectfully disagree, they are not complex to use at all. It is just sending ASCII characters back and forth. Once you understand the logic, it is very simple in my opinion.
Great stuff. Can you do a video about sending images dynamically with icon overlay? We are stuck with "static" images. It would be cool to send a hex image string like profile picture etc. to the display.
Hi! I follow my own pace with this video series and such topic is not yet on my list. But I wrote it down and when I arrive to that area, I will try to work on it. But I cannot promise any date and time.
The Arduino code is available on my Patreon. The "display file" is not available because it is display specific. However, you can follow the video and create the same files.
hi! when i press ENTER , first page is not getting displayed. for ENTER i selected basic touch module under Touch control, checked the Full QWER keyboard, clicked on set button and clicked on Enter under keycode....is it correct?could u guide me
There are 2 types of "enter" if I remember correctly. One is for confirming (acts as "OK") and another is for line break. Check if you use the proper one.
How to print string[text message]from Arduino controller to dwin display?....like in my code i am sending ascii values if i changed to char values it is taking the ascii values but i need text message how to do this
I am recieving A9 CB F9 54 FD FF FD 00 data from dwin not recieving the data with 5A A5 header . Am i doing something wrong . Any thoughts on this problem . Thank you.
I'm using the DMG24240C013 screen, and I applied the same steps as you described. After changing the Touch-sensitive Variable Changes Update setting to Auto and loading the CFG file I created onto my screen, the backlight went off, and I can't see anything. Even if I try to load a different project, the issue remains unchanged.

Hi! I tried to make a very similar procjet using a DMG12480C068_03WTC.

Even for the same text, the message is different. For exemple, I receive 1A 41 01 20 20 24 24 AE BF BF for text "ttt" - same time, if I send 0x83 command to read VP 0x1000, the answer is correct 5A A5 10 83 10 00 06 74 74 74 FF FF Is it anything that I missed?
