Re: How to configure the composite video output to a 7" LCD?

I tried every configuration ... I do not even get anything on the LCD again. As I wrote above, I had some hieroglyphs at first but now - even after setting up a completely new raspbian on another sd card, nothing works. Any ideas, impulses, ...? The LCD works. It has 2 inputs and one is the camera t...

Re: How to configure the composite video output to a 7" LCD?

I am still trying with different images. Please, let this thread open. :) I could only test the HDMI port with a VGA adapter because I do not have an adapter from the Raspberry Pi's composite video output to my VGA monitor. So, I only can test it in the car and then add or change anything in my flat...

Re: How to configure the composite video output to a 7" LCD?

that means it will ignore the lack of hdmi, and always force it into hdmi only mode! you want to turn that off if you want composite also, which model of pi are you on?, the 4 needs an extra setting to enable composite output I tested all variations. Nothing worked. That's so curious. So, I have to...

Re: How to configure the composite video output to a 7" LCD?

i believe the composite output is disabled if hdmi is detected on he rpi4, composite remains off by default and you need to enable it in config.txt I uncommented the line `hdmi_ignore_hotplug=1`. fyi, it is 1440/3 pixels as they count r, g, and b separately. Thanks. But I didn't set anything yet. W...

Re: How to configure the composite video output to a 7" LCD?

I am sure because I have another monitor and there I can see the booting and I can use it.
And in the camper I can connect by ssh local. So, it runs. But I cannot see anything on the LCD but on another monitor.

How to configure the composite video output to a 7" LCD?

Hello Pi-Fans, I have a 7" LCD color monitor with 1440 x 234, PAL/NTSC, 16:9 in my camper and want to use it for my Raspberry Pi 3B+. And I already have (the right) cable and connected it (composite video output of the pi to cinch input of the LCD). First trial: The blue stand-by screen changed to a...

Re: HDMI output to RCA/cinch input?

All Raspberry Pi computers have Composite Video out which can feed directly into a TV or monitor which has an RCA / Phono / SCART connector. It would probably be easier using that than trying to find an HDMI to composite interface. Really? Where can I find it? That sounds funny because I tried a lo...

HDMI output to RCA/cinch input?

Good evening! I want to connect the HDMI output of my Raspberry Pi 3 with the cinch input (RCA?) of the LCD-Display of our camper (for the back camera, 2nd channel). What type of connector or transformation unit do I need? I do not think that the solution is only a cable because there must be a conv...

Re: Why this GPIO-sequence and which GPIOs for Interfaces?

Thanks for your answers! It is very difficult to route the traces (tracks) even with a 6 layer board that the RPi has and using automatic routing software. So I think the RPF did as well as possible with the layout that we now have. I'm sorry if it sounds like "I don't like it". I was just wandering...

Re: Camera Rev 1.3 from China?

Crazy, I tried a lot and in the end I recognized that the connection between the camera objective wasn't connected well to the module. I pressed it, it clicked and now it works! Wow.
Thanks because without your answer I don't think that I had tried more!

Why this GPIO-sequence and which GPIOs for Interfaces?

Hello in a great programming New Year! I have two questions: 1: The more philosophical question: Why the pins are in order like they are? Why they do not build it with 2 Pins on one side with 5V, 3.3V and GND, then all the programmable ones? Why this "chaos"? Is this because of the micro controller?...

Camera Rev 1.3 from China?

Hello,

I'm using a normal PiCam for some weeks and now I bought a cheap version from China for more experiments. But with the same installation and coding the new Camera doesn't work? Is it defective or can there be a difference?

Thank you

ssh: write: Software caused connection abort (only sometimes!)

First, I want to thank you for the idea of the Pi. It's great and I use it every day! I use it headless and have no problem with ssh from my MacBook. But today ... When I try "ssh pi@192.168.0.172" or per ethernet-cable with "ssh pi@raspberrypi.local" there is shown: write: Software caused connectio...
