- DWIN is a high-tech company specializing in human-computer interaction solutions. In the field of human-computer interaction, DWIN will always be your most reliable choice. In this getting started tutorial, we will learn to set up DWIN 4.3-inch TFT LCD Display called DMG80480C043_02WTC. It is a 4.3-inch colour LCD Display with 800X480 Pixel Resolutions called a T5L LCD Module. It operates between 4.5V to 5.5V and is compatible with all microcontrollers including Arduino, STM32, Pic, 8051, and others. We need the FCC-10 terminal cable called FCC1015A and the HDL662B UART to USB Converter Board to establish communication with a computer. To load the firmware as a factory demo, we need an SD Card. Finally, a beautiful GUI can be created without the use of any programming.

In this video, I show you these excellent DWIN displays I got from the manufacturer. I first review and discuss the properties of both displays I got, and then I pick the smaller display (easier to handle for a demo) and show you how to create a GUI. I also show how to transfer information in both ways: display-to-serial and serial-to-display, so you will get a lot of information available to be able to start working with the display.
I also wrote a detailed article about the exact same content that I show in the video. If you prefer reading instead of watching videos, please visit my website:

Thank you so much for explaining variable issue at 34:15 , I was stuck with it for last 1 day. Cheers!
me too! thank you so much!
Glad it helped!
nice explained we like you continue the series.
Thanks! There will be a set of new parts, it just takes a lot of time to prepare them.
Amazing! I sincerely appreciate it.
Thanks!
Thank you for the tutorial!
Very well explained please continue the series.
I have a question. On win displays there are two usart ports
Do you know how to use them?
Is one of them used to send data from the screen while the other one is for receiving ?
Or how does these two usarts work?
You are welcome! There will be a continuation in the near future, stay tuned! :)
One (UART2) (TX2 and RX2) is for communicating with the microcontroller. The other (UART1: RX4 and TX4) is a so-called "expanded serial port". If I am not wrong, it is probably used when you use the display with the HDL662B Adapter and connect it to the computer. It is probably the debugging port.
Thank you for your long and valued video about 49:38!💝
My pleasure! More will come soon.
Very good tutorial. Wish I have found this earlier 😅. Have gone thru lots of research to get the display working. Now I'm trying to enable / disable or hide / unhide a button like normal GUIs. Any clues to do it ? I mean to control the touch components.
Thanks! I haven't tested hiding/disabling elements, but it must be possible. I will make a series of videos on these displays, so I will cover that topic too. Stay tuned!
harika anlatmışsın teşekkürler
You're welcome!
Hello. Thanks you for the useful guiding.
I have trying to do same as your did but I have a problem is I can not make my screen display vertical, can you help me to show what did I do wrong?
Hi! Have you checked my other video on configuring the display? I am pretty sure that I explained how to deal with portrait and landscape mode. You both have to take care of the picture's aspect ratio and the page resolution.
Is it possible to download a project from the display back to an SDcard (in case you lost the program on the computer)?
Hi! AFAIK, it is not possible. Nor to SD card, neither via serial.
Can you please kindly answer ?Can these DWIN HMI Display be used as controller for claw machine?
Hi! You can use them for any purposes you want. But keep in mind that these are only displays. The real work is done on a microcontroller connected to the display.
When you mention, at end of video, about competitors, you mean about 4DSystems ?
Nextion was on my mind.
very interesting, thank you! I wonder how DWIN compares with Nextion displays. any idea?
Thanks! I worked with Nextion as well, and the first thing I immediately noticed is the price. DWIN is cheaper! Also, DWIN uses their own chip instead of an STM32 microcontroller which is very advantageous, especially in today's chip shortage. DWIN, especially after already using Nextion in the past has a bit stranger approach in programming, but once you get used to DWIN's programming, it is actually better. In fact, you don't even need to write a single line of code for the DWIN displays, however you need to spend some time understanding how the VP addresses work and how to interpret the data stream. Also, DWIN gives you a *FULL* control for their displays. It does not matter if you buy their cheap $20 or their expensive $100 display, you will be able to use both of them with the same functions. Or at least I could not find any limitations yet. The other manufacturer blocks certain functions, for example I cannot put a switch or a combobox on my basic Nextion display. All in all, it is cheaper but better. I will make more videos on these displays because I think they deserve more attention and they are not really discovered by makers yet.
@@CuriousScientist that's fantastic, thank you VERY much! I have an application in mind where I would like to display a live feed from the camera, and possibly freeze a frame and make that into a button. I'm quite sure I cannot do it with the Nextion displays I have, but I've seen videos on the DWIN channel where at least the playback of a live camera feed is possible, although none of those I watched have any instructions. it would be FANTASTIC if you were to cover that. thanks again for the video and the quick reply!
I cannot promise that I will cover it let's say in two weeks, but I noted down this idea and will try to incorporate it in my "DWIN series".
@@CuriousScientist thanks, man! I am in no rush, so don't worry! :-) I'm a long time subscriber, so if you make it, I'll catch it
Can we give power to display board directly using a 5v power supply and connect it with Pin +5v and gnd ? While flashing and in regular use
Sure, you can use an external power supply as long as it is the _only_ power supply. Do not connect the serial adapter and the external power supply at the same time. Also, make sure that the external power supply can supply enough current (1 A, if I remember correctly). Actually, these details are clearly stated in the manual of the displays. Read it!
@@CuriousScientist Thanks a lot it helped a lot
Cheers! Glad to help!
thank you for the tutorial
any idea how to connect the dwin dmg10600c101_15wtr with arduino?
Hi! In the same way like I did. It also uses UART.
@@CuriousScientist can i contact you in whatsapp i need to illustrate to you the problem
I don't have WhatsApp. For display related issues you can directly contact the manufacturer. Their contact information is in the description of the video. WhatsApp too.
No my question is that the display output is 8 volt and the arduino only handles 5 v i need the name of the adapter that connect the display and the arduino
I don't know how you managed to measure 8 V, because the typical voltage level of the IO is 3.3 V and the maximum is 5 V. Something is not correct there.
I accidentally supplied 12 volts to the DWIN screen, which should have been powered with a 5-volt adapter. I pulled it out, but I'm not sure if the screen is damaged. Can you please let me know?
Try it with the correct power supply and hope that it will work.
I have a unit with one of these screen and the j it arrived damage and I’m looking to replace it. Can the software be read then written to a new screen so it will run the unit?
Hi! There is a section in the DGUS toolkit that allows you to download certain files from the display using the serial connection. But I don't remember exactly which files can be downloaded. I recommend you to check the datasheet of the displays, or just contact DWIN. They are super helpful.
@@CuriousScientist thanks for the reply. I am in contact with them and like you say seem really helpful. They say I need a set code from the company that supplied me the unit but I can see why I can’t just unsolder the lcd off the bit with the chip and solder the new one on to retain the software
You can try the resoldering solution, but it sound a bit too complicated. Isn't it easier to just ask for the files from the company? You can explain them that you had the display damaged. I believe they would understand it and they would probably help you.
Is there a way to retain a value after rebooting? Let's say I need to retain the slider value upon rebooting
Sure! Save it in the eeprom of the MCU, then reload it from there upon reboot.
@@CuriousScientist when you say "eeprom of the MCU", are you referring to the MCU of the DWIN, or the MCU of the arduino that's broadcasting the data to the DWIN?
The Arduino's eeprom.
@@CuriousScientist Thank you for your help and the very useful dwin tutorials
If anyone needs further info, please google 'ESP32 Save Data Permanently using Preferences Library'
I followed the same in the video. Once the sd card process is completed, I have removed the SD card and power on again. But i ended up with a black screen. May i know where i went wrong?
You first power off the screen, then remove the SD card!
I don't know where you went wrong because I don't know what you did. Did you name the file correctly? Did you generate them correctly? Are they in the DWIN_SET folder? Do you have the font (hzk) file in place?
@@CuriousScientist yes I have done all the things as you have said
please make videos on linux lcds and also make on linux lcd interface with other microcontrollers
Sure, if you sponsor me. I don't make videos on requests for free.
i have a question about a DWIN screen, maybe you can help me figure it out...
at some point during flashing of a screen for a 3d printer i flashed a firmware onto it that was rotated 90degrees, upon flashing back to the stock firmware i began having issues with touchscreen
basically the left half of the screen is working the other isnt, but not dead, to press a button on the right side of the screen, i have to touch the right side of the left half,
to press a button on the left side of the screen, i press the left side of the left half..
so basically it is as if the touch area is squished together and left aligned...
is there a way to fix this ? and how ?
the other firmware must have changed or written something into the screen, that dosent get changed back by the original firmware...
Hi! Did you change the configuration file that contains the orientation (the t5l file)? You need to change it as well in order to affect the rotation of the display. You can regenerate the file from the DGUS software and then upload it with the rest of the files.
@@CuriousScientist I don't have a rotation issue, I wanna use the original firmware again, and now the touchinputs are messed up with the original firmware, the rotation I fixed for the alternate firmware but then I decided to go back to the original one cause I liked it better and now touch isn't working as it should
To me it sounds like a rotation issue. The screen alignment change but the power-on display direction remained unchanged, therefore the touch are is also according to the other configuration. Why don't you contact the developer of the firmware? They must know if any of these settings are incorrect. You can also try to upload an empty display with the assumed-to-be-correct power-on display direction, and then reupload the original firmware.
@@CuriousScientist i did upload one following your tutorials, but then i either dont have touch or i have the same touch issue ...
and the x and y directions for touch are all correct its just squished ...
i did contact the manufacturer of the 3d printer for a fix but they do not offer firmware downgrades etc, they told me ..
was just wondering if someone with knowledge about the DWIN system knows how to fix it
Did you choose the correct resolution according to the _EXACT_ type of your display? They can look identical, but have different LCD panels with higher or lower resolution. That could explain the squished touch controls maybe.
I am having trouble with Variable Icon in DGUS. How to control transparency of added icon?
I have added back and white monochrome jpgs.
I am able to change my icon based on input but my black background in my icon is getting removed. I have tried changing display mode but it is not changing anything. I have tried other color images as well but their background is also getting removed.
How to control and turn this off is transparency setting?
Thanks
Hi! I haven't worked with transparency, so unfortunately, I do not know the answer. I recommend you to look at the datasheet of the display, it explains well how it should be implemented.
@@CuriousScientist thanks for response.
I managed to "solve" it, it seems the changes that I made in the DGUS for my VAR_ICON are not reflecting in their simulation mode. But when the ui code is uploaded on display, changes are working as intended. So problem is probably in their simulation I guess.
Yeah, you kind of missed mentioning that you encountered this issue in the emulator and not on the actual display... I emphasized several times, even in comments that the emulator should not be trusted, it is riddled with bugs.
@@CuriousScientist I probably overlooked them as I thought problem was with only transparency code or DGUS version perhaps. Thanks for the info.
Hello, I have some issues regarding the communication. Hex values doesn't come the same in slider display and ADC value, even after sending display isn't taking it. Could you please help
Hi! Could you rephrase your question? I don't really understand the issue, sorry.
Hello, I am not able to send Or receive the values through display. I have set the address and all the settings as per instructed in the video but still not able to communicate. What can be done?
I don't know how you are trying to send the command, so I cannot help. You need to provide more information. What baud rate do you use?
You need to enable TTL mode to ON. In my board you have to solder (short) two pads in the back. They're labeled.
Wow, this is new to me! Thanks for your contributions!
i used NEXTION DISPLAYS in past.......they are same quality as DWIN but TWICE the price
Each of these display families have their own advantages and disadvantages.
An error occurred while upgrading the screen and it became a black screen that does not work
Can you help me to restart it
DWIN LCD DMG80480C050_03WTR
can you help me
I can't find a way to reset the screen again
Please contact their customer service. I am not a DWIN employee, I am just a dude working with these displays.
How to send decimal numbers from ESP32 to Dwin display?
It is the same way as I send the ADC values to the display. Watch the video.
@@CuriousScientist Thanks for the reply. I am getting errors in the Arduino IDE. on seding integers it works fine but when changing the data type to float, it starts giving errors.
These lines to send int data
Humidity[6] = highByte(h);
Humidity[7] = lowByte(h);
mySerial.write(Humidity, 8);
But on changing h datatype from int to float, getting error
"error: invalid operands of types 'float' and 'int' to binary 'operator>>' #define highByte(w) ((uint8_t) ((w) >> 8)) "
It would be helpful if I can get help in this.
You cannot treat float as an integer. You are trying to do operations on float which can not be done on float. Furthermore, you cannot directly pass a float to the display if I remember correctly. You have to send an integer and you have to know where to put the decimal point. For example, if you want to put "56.34" on the display, you send it as "5634" and then within the display you have to account for the placing of the decimal point to make it "56.34" again. Read the manual of the display, it is described there.
@@CuriousScientist Thanks, i got it. I'll try and let you know.
Hey, just to let you know. It worked. Thanks for the help. you are awesome☺
Can we play video on this display
Hi! As far as I know, it cannot play a video as an LCD or television...etc., but it can play a video from a camera. It is described in the DGUS handbook.
Not working help pls
Hi! If your display is not working, contact their customer support.
PЯӨMӨƧM 👀
?
Well, the software is complete trash tbh
It is not perfect, but it is possible to use it.
