håller på och ska bygga ett litet 1wire-nätverk hemma för att hålla koll på värme och luftfuktighet och säkert nåt annat kul man kan komma på. tanken i längden är att även vårt gamla skralltiga värmesystem ska bli automatiskt men det dröjer nog. inte så hemma på det här med hårdvara så ska hur som helst bli fasligt spännande! #hemmafix #1wire #1wirenetwork #raspberrypi #hemautomatisering
Patch implement runtime configuration option for setting GPIO pin like 1-Wire master device. When use module you may use it on follow way : modprobe w1-gpio (standard hard coded pin 4 will be used) modprobe w1-gpio gpiopin=18 (pin 18 wi...
Apparently there is a way to change which GPIO is used for the 1-Wire bus on a Raspberry Pi. I haven't tested this yet, but I'll give it a shot once I've verified that I'm running the correct version of Raspbian.
There is also a little bit in here on fiddling with git repo's.
To change the 1-Wire bus to pin 8, add:
bcm2708.w1_gpio_pin=8
to /boot/cmdline.txt and reboot.
Mi sa che e` andata ...
cat /sys/bus/w1/devices/10-0008029444b6/w1_slave

Risponde sempre "127687" :'(
Sensor Suhu 1-Wire DS1820 dengan Codevision AVR
Sensor Suhu 1-Wire DS1820 dengan Codevision AVR
Sensor suhu DS1820 adalah sensor suhu jenis digital, rentang suhu yang dapat diukur antara -55 C sampai 125 C, terdiri dari 3 pin yaitu vcc, ground dan DQ (Data input/data output). Komunikasi mikrokontrol dengan sensor terjadi lewat pin DQ.
Berbeda dengan sensor LM35 yang menggunakan interface ADC, DS1820 tidak menggunakan interface ADC melainkan 1 wire, data yang dikirimkan ke mikro beresolusi 9…

Running on Raspberry Pi with very cheap 1-wire technology. And some curl, cut, grep. 1-wire has usb interfaces, so this can be done on standard pcs too. And in addition to temperature probes, there’s humidity and moisture and movement and and and. Ask for code and I’ll point you to the repo on github. And, yeah, kinda hot in here.
