I have handed myself a 2-week ban from the Raspberry Pi forums, in solidarity with @DougieLawson After that it will be time for my annual hibernation to mark the season known in the No...

Welcome to the Raspberry Pi forums.

Does 'Pixel' mean the Raspberry Pi Foundation Desktop graphical user interface?

Re: While writing image to SD Etcher complains :: it looks like this is not a bootable image; the image does not appear

any ideas



Perhaps try seeking advice for your non-RaspberryPi hardware in a place that is not dedicated to Raspberry Pi hardware?

This previous thread might have provided a clue...

Yes.

Balena have a worked example: https://www.balena.io/docs/learn/gettin ... rrypi3/go/

Re: I can't make apt-get work

Welcome to the Raspberry Pi forums.
What I'm doing wrong?

Maybe you are not doing anything "wrong."

Perhaps that package (packages) is not available in the Raspbian (or Debian) Stretch repositories.

Re: Python3 Can't use ELIF

Welcome to the Raspberry Pi forums.


Can any one tell me where I am going wrong?

In a word - indentation.

elif has to be preceded by an if. There is no corresponding if at that level of indentation.

Or alternatively, the elif should not be indented.

Re: Transfer a Picture from Pi to Arduino via UART

If you could help me with the problem I am asking about it would be a great help.


Personally, I find it difficult to offer help without first understanding the problem to be solved. If that approach does not suit you I will withdraw and leave you to accept help from someone else.

Re: Transfer a Picture from Pi to Arduino via UART

Why do you need the added weight and code complexity of the Arduino.

Why not ship the file wirelessly from the RPi to the 'groundstation'?

So the RPi and its camera are airborne?

Where is the Arduino? If you are making a serial port connection is it also part of the same payload?
