Re: Official 7" Touchscreen

Hi guys Think I just sorted it !!!!

Re: Secure online banking

You need to be careful or your little hobby project might result in a security risk that acts as an entry point into your network. They can’t perform secure booting such as ARM Trustzone, and the SD card and operating system are not easily encrypted. I think that this post wins the oldest necro awa...

Re: Raspberry Pi Desktop for PC versus Pi3 Raspbian

RPD is basically Debian with a different graphical interface. So installing GPU drivers for Debian and whatever GPU your PC has is the way to go.

I've been looking at touchscreen stuff recently, if I have time will look at this.

However, I am very busy.

The 3 only has one camera port exposed, although the SoC can support two, only on the compute module are both available.

Just to confirm, in config.txt you have added the line lcd_rotate=1 Are you running the latest firmware? In the latest firmare there is also display_lcd_rotate which might be worth a go.

Perhaps its time to learn another language such as C++ instead of Java ?
C++, even C++17 is fully supported on all Pi's.
I suspect that is probably the best option. No real chance getting that java version going I guess.

Python, c++, Ruby might be good options..

Re: C programs written in ubuntu to run on raspberry pi

You need to recompile the code on the Pi itself, since on Ubuntu (I assume) it would have been built for the x86 architecture, and Pi is ARM.

Yes, this is a known issue when using non-standard rotates. I know what causes it, but have not yet found a neat way of fixing it - I do have a nasty hack but would rather not use it.

Re: Enclosing and cooling a pi zero w in a warm moist environment.

A Pi0 should stay pretty coool, if it get over 85 it will throttle anyway.

You could connect the heatsink though the case to another on the outside if it does get too hot.

Re: GUI changes not being saved

If you are running on a Pi-top, installing the pi-top utils (pt-hub etc) installs a service that runs at startup that resets a bunch of desktop settings to Pi-top's chosen defaults.
