Following on from the weather station wiringPi page… So I’ve had a thought on the one-wire temperature sensor…. 1-Wire is a well defined system and works well on the Pi, however wiringPi has a “pin” based system, so how about … Continue reading
After setting up and testing some of the hardware in part 1, its now time to add the devices into wiringPi. As in part 1, I’m writing this as I go, to give you an idea of my thoughts and … Continue reading
The Raspberry Pi Weather station is a hardware and software system designed by the Raspberry Pi Foundation designed to let schools, etc. record their local weather. The system was produced in conjunction with Oracle who are providing a centralised database … Continue reading
I’m asked many times why wiringPi has its own pin numbering scheme for the Raspberry Pi, rather than use the native hardware pin numbering (which is can also use, along with the physical pin numbers).. The answers are simple… Firstly… … Continue reading
So early evening last night (Saturday 19th Match), a nearby neighbours power went off… They called Western Power who at about 9pm decided that it was an emergency… Due to a young person being in the affected house. So at … Continue reading
On the first birthday of the Raspberry Pi (That’s the first anniversary of the original February 29th launch!) The fantastic foundation brings out the Model B v3. Features over and above the existing Pi Model B v2: Wi-Fi and Bluetooth … Continue reading
So as well as technology, I love baking – to the extent that I bake stuff to sell with all the shenanigans that goes with that. Local authority inspections, food hygiene certificates, insurance, blah…. Some bread I made … (Devon … Continue reading
A quad-core Raspberry Pi? Sure. Why not. Put 4 x ARMv7 Cortex-A4 cores on the chip and lets give it 1GB of RAM while we’re at it. And here it is. The Pi v2. Unlike all previous Raspberry Pi’s the … Continue reading
I’ve had two people recently email me regarding their Raspberry Pi sensor monitoring projects stop after 49 days… The reason is simple, the solution slightly more complex, so what’s going on? The wiringPi GPIO library has a function: millis() which … Continue reading
