Re: Damaged HDMI ports on two seperate Pi

I do not have a switch. But yes, it has probably been the same cable in both cases so perhaps I should eliminate that variable as well. The Pi was using different power supplies so no common denominator. Currently using an old D-link wall wart, seems to work and has more than enough amps, no low vol...

Damaged HDMI ports on two seperate Pi

Basically, how do you prevent this from happening? Is there some best practice to be followed when connecting HDMI to avoid this sort of nonsense? I've now had my second Pi (a Pi 3) damaged from what must have been a static charge. Same setup, same Acer monitor, a couple of years apart. No output si...

Re: Screenly OSE -- Digital Signage for the Raspberry Pi

Quick question: Is there a way to force / push a reload of a web page / asset using either OSE, Pro or 2? I have this stats page that I only want reloaded when on external events. Right now I have a XMLHttpRequest going every 2 seconds and ob_get_contents() and I guess I could also make Screenly Pro...

Re: Screenly OSE -- Digital Signage for the Raspberry Pi

Just discovered Screenly OSE / Pro and now have a quick question: How does the Pro version fetch its data from the server? By timer or is it pushed on demand? Is it possible to run from a RPi that has no public IP / is behind a corporate firewall? Similar to how TeamViewer works? Hi Bjorn, You can ...

Re: RPi Cam Web Interface

Also, on another note, would it be possible to interact with RPi Cam Web Interface from home automation software? Telling it when it needs to record video or snap images? I'm thinking of having a PIR motion sensor instead of the motion software. It would be a great way to have your cake and eat it t...

Re: Connecting peripherals to the same GPIOs

You'd need to connect the devices to different chip select line, one to CE0, the other to CE1. See the diagram at http://elinux.org/RPi_Low-level_peripherals The other signals are shared (MISO, MOSI, SCLK). MOSI/SCLK are outputs from the PI so you can ignore as a voltage problem. MISO (Master In Sl...

Re: Connecting peripherals to the same GPIOs

Each of the 2 peripherals you want to use needs an SPI bus connection, fortunately the raspberry pi has two SPI bus connections, which will allow you to connect both of these with just one change of pin. (One of the 24's needs to be changed to 26). Ok I see. So the other pins can accept two connect...

Connecting peripherals to the same GPIOs

I've tried to look up the answer to this on my own but I'm just stumped. Basically I want to connect different radio modules, 433MHz (pilight with the prefilter) and 2.4GHz (mysensors) to the GPIOs, and it turns out they require the same specific pins (19, 21, 23, 24): http://www.mysensors.org/build...
