Re: Allegro on Raspbian?

For anyone else who comes across this thread.

If you want to compile allegro 5, check out these instructions http://www.stuffaboutcode.com/2016/11/c ... ry-pi.html

Allegro 5.2 + runs really well on the Pi (particularly the Pi 2 & 3).

Re: As gift for 12 year old?

I personally think a Raspberry Pi is a great gift for a 12 year old interested in computing. Remember he may need more than just the Pi, power, sd card, keyboard, mouse, monitor unless he already has those things. If you decide to get a Pi, have a look at the book 'Adventures in Raspberry Pi' its a ...

Re: Doubts about the language to use

If your objective is to create 'bare metal' code your choices are probably assembler and C. If you are an inexperienced programmer this will be an uphill battle, simply creating an environment to compile, test and run your code is (almost) a project in itself. Have a look at "Raspberry Pi Bare Metal...

Re: (Yet another) Vintage Pi-Radio

I think I used exactly the same rotary encoders in my radio build ( http://www.stuffaboutcode.com/2015/05/raspberry-pi-vintage-radio-build.html ) - KY040? I struggled initially with the KY040 as it doesnt use the traditional gray code - my blog post about it is here http://www.stuffaboutcode.com/201...

Re: Need some verification from more experienced people

You wont have a problem.

Connect your buttons using a pull up to ground, so that when they are switched you connect ground to the GPIO.

Use the GPIOs to switch a relay (or probably just a transistor) which connect a separate 12v power supply to the LEDs.

Re: Start and Stop Raspberry Pi 3

All good advice.

I would take a simpler approach though and just leave it on all the time! The Pi uses very little power (even less so when idle) and it really isnt going to hurt it. I have Pi's which have been permanently on July 2012.

Re: Pi3b block on splashscreen

If your image goes back to September (and was presumably in an older Pi), it could be because your OS needs upgrading.

If so, put your SD card back in your old Pi and upgrade using:

Code: Select all

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

You are going to need some sort of relay which can switch your computer on based on a signal from your Pi.

It sounds like a very doable project.
