樹莓派 Raspberry Pi -9 Channel  1-Wire Board

一、產品特色

The 1-Wire port is based around a DS2482-800 & DS2482-100 I2C to 1-Wire bridge device. The DS2482-800 provides bi-directional protocol conversion between the I2C port on the Raspberry Pi and any attached 1-Wire® slave devices. An ESD Protection Diode is used to protect the Board and Raspberry Pi from electrostatic spikes on the 1-Wire port. Connections to the 1-Wire port can be made through pin on the PCB.

with DHT22(AM2303) Digital Temperature Humidity Sensor socket))

with DS18B20 Temperature Sensor

二、18  — > DS2482-100     1C –> DS2482-800

三、It appears that OWServer has found 9 1-wire busses, DS2482-100 is bus.0      DS2482-800 is bus.1 .. bus 8

四、i2c addresses of each bus.

bus.0   …..   18                 bus.1 to bus.8    … 1c

五、with DHT22 (AM2302) Digital Temperature Humidity Sensor socket
