Raspberry Pi can do a lot of interesting things, it is equivalent to a small computer, installed on the system can be used as a small server home. With this small server, you can implement an "offline" Download machine. But offline download here is not really offline, because the Raspberry Pi is still online-since the

, because the USB to the serial port of the minicom to communicate, and no garbled, the transmission of all the correct data2. Arduino mega2560 can transmit data, but there is garbled, possibly because the mega2560 serial port has the relation.Since the module is good, I think of another test method, a module using a USB port to the PC, and the other directly to my Raspberry Pi on the UART interface. The re

There should be a lot of students in how to use WiFi for Raspberry Pi connection encountered some bottlenecks, the internet said that generally need a router, in fact, we download a 360 free WiFi can, equivalent to the computer as a router to share the network, Xiang Fine steps are as follows:Step one: Download 360 free WiFi, set up your username and password.View 360 free WiFi IP address, enter ipconfig in

Raspberry Pi II has come! This is a boon for those who want to study Android. The official configuration is as follows: 900MHz Quad Core ARM Cortex-a7 processor (Broadcom BCM2836) 1G LPDDR2 SDRAM (Micron) Two full-size USB ports (available for power supply) One MicroUSB interface A full-size HDMI interface 3.5 mm Audio Interface RJ45 Ethernet Cable Interface I used

Recent research has developed Java programs embedded in the Raspberry Pi and intends to communicate with Salesforce. Need to develop a Java Web server, do not want to be so complicated, so I intend to write in the Linux system/etc/rc.local want to execute the statement, such as Java–jar/root/test.jar. But when the boot, found/etc/rc.local inside the command and did not execute, this is a headache thing. For

Recently in the toss Raspberry Pi, at that time also did not pay attention to, look at the price, bought Mercury network MW150US Ultra-small 150M wireless USB card. But the tragedy was to use iwconfig and not recognize the wireless card But with lsusb words can see MW150US with is Rtl8188eu chip, search on the network, finally found a solution 1. first download the latest Linux kernel for compiling and inst

To set the time zone for the Raspberry Pi, use the following command: sudo dpkg-reconfigure tzdata After executing the command, you need to wait a little bit, then come out the time zone selection interface: Note that if you do not see this interface after executing the command, but instead see a bunch of garbled characters, then you need to set up SSH or other terminal character encoding The

What you need to know before installing1. Coolpy is a Nodejs-based IoT platform (official website http://icoolpy.com). Note: The domestic IoT platform has the LEGO network , Yeelink and so on, but only coolpy is open-source. 2. Node. JS is a platform built on the chrome JavaScript runtime to easily build fast, easy-to-scale Web applications Note: Therefore, to run coolpy, you must first install the Nodejs. 3. The new coolpy does not use a database but is stored locally as a file. Note: So a lar
