... The question was, how to connect it with Scratch? Scratch will need a driver module or you're going to have to wiggle GPIO pins in the right order with the right timing to drive it from your scratch program. You may by able to do that with Simon Walter's ScratchGPIO ...

... The cable is exactly the right length so the screw holes in the adapter will line up with the mounting holes in the display. If you tug on it or wiggle it around too much when fastening the adapter to the display it will pull the cable out slightly and you'll only have a white screen. I'd remove ...

Hi I am very new to RPi and Linux/command-line. I ran this script as described and needed to do the bash -x ./rpi-wiggle command for it to work. I ran it via putty and everything proceeded to the reboot option, to which I said yes. It rebooted very quickly and I watched on the connected ...

... can't be overwritten (unless you choose to give a user's account root privileges). Combine that with the change that allows non-root users to wiggle GPIO pins and it's all a whole lot more secure. Thanks Dougie, yip that is correct, PiNet would be a perfect solution for this. You maintain ...

Not sure about pigpio using the pigpiod. Have to check.

Mind you I'd rather it did not. All seems to get crazy heavy weight just to wiggle some I/O pins.

... So it should be possible to get any webserver running with userid=www-data gid=www-data to be able to read / wiggle GPIO pins without needing sudo to get root privileges.

... Because it looks like running that as a stand-alone webserver is going to be the easiest option at the moment. Making Apache2, Lighttpd or NGINX wiggle GPIO pins (in the pattern needed for the Energenie stuff) isn't something I can hack together for you on Xmas Eve. get pi-power installed with ...

... of doing it was to write a server that subscribed to a bunch of MQTT topics, then the non-privileged client only needed to publish a message to wiggle a GPIO pin.

Is anyone else having trouble connecting otg cables to the Zero? I have 2 that I've tried and both sometimes need a bit of a wiggle to get the Zero to realize there is something connected. Both cables have worked perfectly with various tablets I have used over the years, is the data ...

... a performance advantage over previous models which is quite noticeable even during casual browsing. I would be curious to know which board can wiggle an I/O bit faster. The IPC of the ARM1176 is less than the one of the Cortex-A7, so the Pi2 is faster by a good margin on single-core

... a performance advantage over previous models which is quite noticeable even during casual browsing. I would be curious to know which board can wiggle an I/O bit faster. How fast depends on the speed one can launch with a good overarm throw !

emma1997

That depends on your definition of "faster". Certainly 1000mhz is faster than 900mhz. As I mentioned the 2B does have a performance advantage over previous models which is quite noticeable even during casual browsing. I would be curious to know which board can wiggle an I/O bit faster.

... It's simply better to never open that can of worms. I think with a 4.1.7 (or higher) kernel and the gpiomem module it's going to be easier to wiggle GPIO pins from Apache2 (or Lighttpd or NGINX) without needing sudo or root privileges. I just have to find a way to set the environment variable ...

... far and suspect Rasbian may have changed again since those libraries. Or maybe they were before Rpi2. Do you or anybody else have any ideas how to wiggle a Rpi2 pin with the simplest possible code?

DougieLawson

... idea. The main thing with Raspbian on the RPi is that the use of root is much more open than on a regular system because of the need to be root to wiggle the GPIO pins from python using RPi.GPIO. You can harden the system, starting with an update to the /etc/sudoers file. The underlying problem ...
