Re: Video for 1080x2880

At 30fps, the bitrate is halved, so you could try halving the clock. (to 104M)

Re: Raspberry Kiosk

Your question is very very vague, but on the whole, yes, you can use the Pi as a kiosk. There are a few packages available to do this. Google will find them.

Re: ssh not working in Raspbian Desktop (june 2018)

We don't provide a 64bit OS, so the majority of help here will be related to the 32bit raspbian OS. Raspbian by default does not have SSH enabled. You can enabled it using raspi-config. Once enabled, it should work with no problems. I have never heard of it not working, and I use it all the time and...

I have to agree with Ewan, this information is not widely known at all. I was ready to pick pay almost 3 times the regular price because they were ‘out of stock’ at all the normal places.

No it isn't. it just means we're not ready to say anything yet. We ...

OK, so that table is the timings for 60fps, is there also one for 30fps? Because I don't think the Pi is fast enough to hit those 60fps figures at that resolution. No other table. This is the only one, This is the native for the TFT. If this is not fast enough, using this config the expected behavi...

Re: Video for 1080x2880

So, is the display natively that resolution or is it actually 2880x1080 or are you are rotating it?

The hdmi timings need to be defined to the native display, then you apply rotations.

However, is supect you might be exceeding the limits of the output with that high a resolution AND rotation.

Re: I am missing some fundamental understanding of C?

Where are the variables used in the image function declared? I wonder if you have two sets defined, and its using uninitialised ones. You'll probably need to provide the entire functions to be clearer.

Your loop version is very inefficient. You created an entirety new string, add a load of characters to it, then compare, all of which are lengthy processes. All you need to do is loop for half the string, and compare characters from the front+index to the back-index. Thanks for the reply. You're ri...
