np. it's still looking good here and I've bounced the pi loads, sent heaps of data to the screen and it is ticking away nicely. I shall leave it running overnight and see what it's looking like in the morning.

Re: LCD Garbled ness :(

Any chance you can share your init script please? So your saying with wiring on OLED as 4bit. Init script set to 8bit then modify down to 4bit and it works ? I imagine it's something in the HD44780 chip which doesn't reset usually but does on an 8bit/4bit switch... As long as I understand your solu...

Re: LCD Garbled ness :(

To be honest, im on the brink of binning the whole lot. I went back to a proper LCD and things are fine, right until I add my python program to an init script. Then I get sod all from the display despite the fact that I can see my python application running. Frustrating.... Yes, Time consuming.. Ye...

OLED 16x2 HD44780 woes

Hi, I'm having issues with this (http://www.midasdisplays.com/pdf/MCOB21605G1V.pdf) screen. I've used LCD version of this screen before with an arduino, the oled version is nice as it requires less wires and less current and no faffing about with contrast. This is supposed to be a drop in replacemen...

Re: How to connect a temp sensor, save data and send collected data

<t>Thanks Ciseco. The DS18B20 base board will make my project much easier. Is it possible to address multiple DS18B20s from a single base board?<br/> <br/> Also... when are you likely to have stock of the slice-of-pi boards again?<br/> <br/> With that side of things sorted I need only to determine h...

Re: How to connect a temp sensor, save data and send collected data

<t>I feel really stupid asking this but I'd rather not blow anything up until the PI boards are more readily available but after reading a little on the pages you referred to, am I correct to assume that if I connected one of my zone inputs to pin 12 and pin 6 then in python called…<br/> <br/> GPIO....

Re: How to connect a temp sensor, save data and send collected data

Wow, im really lost now :s  All I know is that the alarm inputs are configured as "Normally closed - Breaking negative or positive voltage loop"

I guess a LOT more reading is required, where to start is the ultimate question

Re: How to connect a temp sensor, save data and send collected data

<t>Hi jbeale, thank you for your reply.<br/> <br/> Yes the XRF does operate at 3.3v and conveniently, ciseco sell a break out board for the pi that not only accepts the XRF but also brings the rest of the GPIO pins up for easier access (here) but im not sure how I would link to the alarm zones on th...

Re: How to connect a temp sensor, save data and send collected data

<t>I thought I would post in here because I wish to do something similar and would like a second opinion on whether my idea is sound.<br/> <br/> I need to collect temperatures from various locations on a site and log them to a database at a central location at the same site. I also want to hook up t...
