So, I was testing in a 15.6" display, and the code for config.txt lets me use as an tablet, but just when i unplug and replug it. Would you know what i possibly could do to fix this please?
You can use the USB-C or USB-Micro (on the screen) to power the set-up, just so long as you get enough power to the system it'll be happy. A POE HAT is also an option (then all you need is a powered Ethernet cord). As a note, I wouldn't recommend powering this system through the GPIO Pins as they won't allow enough current in for the system.
It is a fantastic episode which all the details and references. I'm sure you have to spend a lot of time researching and recording this. Thank you so much. Cheers.
Simple champ, just pull out the SD card gentle and insert your new one. Give this guide a look if you need mate - core-electronics.com.au/guides/dual-monitors-raspberry-pi-4/
Could one use these little screens without the help from a RaspberryPI. For example plug in the screen with its power source into an output from a Camera for a display.
I've been doing research on this and apparently, you can, but I'm still looking to see if one can dim it directly, since it has a DDC/CI monitor control without the need of external source like a raspberry pi, but I'm not sure on the language so the search continues.
It might depend on the video, AMOLED screens suffer from burn in if the same image is on screen for too long. We have some info in the guide if you want to check it out! core-electronics.com.au/guides/amoled-display-raspberry-pi/
Hii great video! I was wondering which lcd display would you recommend if we want to just display the output video of a camera. The camera is attached to the RPi whereby RPi runs face recognition
Heyya 😊 big thanks. It depends really on how pretty/form factor that you want the LCD display to be. The official 7 Inch Touchscreen Display would be a great choice - core-electronics.com.au/catalog/product/view/sku/CE04459 If you desire something more streamline check out this display here - core-electronics.com.au/catalog/product/view/sku/FIT0820
I tried to use a Geekworm 3.5" with a IQaudio DAC+ and after 2 days of trying to get the damn thing to work, I finally started the return. Do waveshares work okay with DACs?
Any advances on the screentearing issue? I've read that it doesn't have that issue on windows. I'm itching to get it, but I would like to know why it's not meshing well with the rpi. Maybe it's just the hdmi connector?
My understanding is Window based machines and Jetson Nano have no issue with screen-tearing in any orientation. I have tried this with different HDMI Connectors and still found there to be tearing in landscape mode.
@@Core-Electronics Would it be possible to test it with a different OS on the rPi? I found this on the forums: "Ubuntu Desktop 21.04 on my Pi 4B 4GB and I can report that Canonical have managed to fix the screen tearing problem" 21.04 uses wayland instead of the x11 window system.
I reckon its going to work just fine. Come jump on our Core Electronics forum and create a new topic on this and we can test it out for you + provide images 🙂
So I have the Raspberry Pi 4B and am looking to blend the video looper configuration with the 3.5lcd or a 4in hdmi lcd. Is there a specific order I should configure the systems?
I'd start with setting up the Hardware and getting your preferred screen all up and running. From there go through the Video Looper process - core-electronics.com.au/tutorials/raspberry-pi-video-looper.html We found the current Video Looping System wont work with Screen that receive the video data through GPIO pins. So long as your using a HDMI port to transmit the video you should be sweet.
Not on that specific HDMI but you'll find a lot of what happens in the above video will correlate when your setting it up. Altering the | config.txt | is a common process for all these types of screens. Good Luck!
Honestly no, some full sized monitors that are meant for Landscape can be flickery in portrait and thats normally a driver issue. So I reckon that is what the situation is here.
could it be used as a philips hue controller, to control light/light colors? I want to make my room more tech. Remove the physical buttons to control the lights...
Well my Waveshare 5.5 amoled display worked for about a month. Stopped using it and then went to use it again on the same device ( Jetson Nano ) and got the blinking green light, and now it is not longer detected on any system with any cable.. Another dissapointed user here, I should have taken the negative reviews seriously
I am new to raspberry pi sorry if my question is a bit dumb. Is it possible to use the raspberry pi with the touch screen display only(with the power supply) with a camera? With no use of a pc or laptop
Absolutely you can 😊 the Raspberry Pi 4 Model B is a Full On single board Computer. You can definitely hook up a screen and a camera to it no problem. The only time you might need a PC or Laptop is when you are flashing a new Micro-SD card that will end up the brain for your single board raspberry pi computer. We also sell already flashed cards so you wont even need to touch another computer if you go down that route - core-electronics.com.au/16gb-microsd-card-with-noobs-for-all-raspberry-pi-boards.html
I reckon it would. The method of adding | Option "CalibrationMatrix" "etc etc " | that you see me doing at 6:38 is a very common method of rotating touch and screen for these kind of displays.
