Scroll content of a window for a 320x240 display

Hello everyone and sorry for the weird title. I recently got this LCD monitor for the raspberry: http://i.ebayimg.com/t/4-3-TFT-LCD-Screen-Monitor-Display-Sun-Shade-Car-Rear-View-Reverse-Camera-/00/s/NDAwWDQwMA==/$(KGrHqFHJCcFCdPcNQ9EBQqupSKm0!~~60_12.JPG It's working really really well and the pict...

Re: Rasberry Pi e Relay

Per chi fosse interessato ho risolto grazie a dei suggerimenti nella sezione Automation di questo forum. Ecco il link del topic dove ho spiegato semplicemente come farlo funzionare ;)

Pieter-Jan5000 wrote:Ok sorry. I didn't take a good look at the board. With a board that has opto couplers on it, the need for a line driver is obsolete. It also offers better protection for the indutive load of the relay. Good luck.
Great, thanks a lot again ;) I knew I could count on you guys

Re: Rpi and relay to switch on/off lights

I don't believe it is. The 8-channel relay board shown has opto-isolators driving the relay coils, so the GPIO pin is only having to sink current through a pair of LEDs. http://www.sainsonic.com/zen/albums/ebay/nichegeek/20-018-102/8c.jpg However from Sainsmarts own website there is a link on how t...

Re: Rpi and relay to switch on/off lights

The gpio pins of the raspberry pi are probably too limited in current to drive a relay directly. Use a line driver like the uln2003a to overcome this problem. Then you can also fix the problem of the voltage by feeding the line driver with 5V Yeah, this is what I was wondering but I found some vide...

Re: Rpi and reley to switch on/off lights

Well... so it doesn't matter if the relay is 5v and the gpio pin is 3,3v?

Rpi and relay to switch on/off lights

Hello everybody. I'm looking for a way to connect the raspberry pi to some sort of relay to switch off/on my home lights. I know there are plenty of tutorials out there but my problem is I know about nothing of electronic, my bad. I wanted to buy a relay like this : http://i.ebayimg.com/t/MODUDO-REL...

Re: rpi - webserver

Apparentemente sembra tutto perfetto. Come ti hanno consigliato c'è un'altra cosa ancora che puoi fare: vpn. Puoi installare ad esempio hamachi e mettere in ascolto ssh solo su rete locale e su rete hamachi. Così volendo puoi lasciare la porta 22 o anche utente root vist che l'ssh sarà in ascolto so...

Re: rpi + hdd esterno + controllo alimentazione

Ciao scusa la domanda stupida ma: perché vuoi spegnere del tutto il raspberry?
Ha senso spegnere e riaccendere i due hdd esterni se non utilizzati e questo puoi farlo per l'appunto utilizzando un relè o ancora in modalità software facendo uno spin-down.

Dai un'occhiata qui.

Re: Problema: file ripristinati al riavvio

Sembra quasi che la scheda sd sia in modalità sola lettura... Prova a salvare qualche file su /boot che dovrebbe corrispondere alla partizione in fat32 accessibile anche in Windows. Se li ti salva correttamente, è successo qualcosa nel file system. Se non salva neanche lì, il problema secondo me è s...

Beh la parte semplice da fare è quella dei comandi.

Rasberry Pi e Relay

Ciao a tutti! ;) Ho da circa un annetto il raspberry e sin'ora lo utilizzo come client torrent controllabile via web, come server apache, php e mysql e come server web per uno scanner. Il mio intento sarebbe adesso collegare il raspberry ad un modulo reè tipo questo . http://i.ebayimg.com/t/MODUDO-R...
