Linux i²c driver module:sudo aptitude install i2c-tools Libi2c-dev2. Load i2c-bcm2708 and rtc-ds1307:sudo modprode i2c-bcm2708sudo modprobe rtc-ds1307After the I²c configuration is complete, if it is the model B of Raspberry Pi, then in the terminal input:sudo i2cdetect–y 1Of course, if it is model A of Raspberry Pi,

Compared to the Raspberry Pi 1 it has: A 900MHz quad-core ARM cortex-a7 CPU 1GB RAM Like the (Pi 1) Model B +, it also has: 4 USB Ports GPIO Pins Full HDMI port Ethernet Port Combined 3.5mm audio jack and composite video Camera Interface (CSI) Display Interface (DSI) Micro SD Card

The Internet of Things (IoT) and Bitcoin (Bitcoin) are all fun new things today, so what's the point of putting them together? In short, it is the use of Bitcoin networks for secure, autonomous trading of transactions involving computing resources, storage resources, bandwidth, data, and even public displays that can help other devices display content. The middle will involve sensors, IoT short-range communication protocols, cryptographic currencies a

output mode may not be ideal. At this time, you need to adjust it. Raspberry Pi 2 does not have a traditional BIOS, so some underlying configurations such as HDMI output areconfig.txtFile implementation. This operation can certainly be performed on a terminal via SSH remotely. However, here we will introduce a small plug-in that can be completed through a graphical remote control. This process is simplifie

another host. It can be used with the default settings by just specifying a hostname (e.g. ping raspberrypi.org ) or an IP address (e.g. ping 8.8.8.8 ). It can specify the number of packets to send with the -c flag.Nmapnmapis a network exploration and scanning tool. It can return port and OS information about a host or a range of hosts. Running just would display the options available as well as nmap example usage.HOSTNAMEThe hostname command display

Raspberry Pi 3 generation Raspberry3 B type Small white introduction first stepHello, everybody, all right! I admit that I was a rookie, yesterday was the first day of real contact with the Raspberry Pi, before they are looking at some of the works of other great gods, feeling this gadget is still very magical, a few d
