how to use raspberry pi

Raspberry Pi--a card-type machine that is based on the size of a Linux system and has only a credit card size. Raspberry According to the inventor's idea, he was designed to reduce the cost of learning program development. You can understand it as a rudimentary version of the computer. Raspberry

Common Raspberry Pi interface number is divided into two kinds of 26-pin a 40-pin, according to their own PI can!Pin definition is divided into two, the first is more common, the second relatively less use, at least I am, but in the next article will use the second serial c

ObjectiveIn the previous article, "Raspberry pi set automatic dialing, build no-line by environment" , the author uses HOSTAPD and UDHCPD programs to create wireless hotspots to achieve address assignment and DNS server settings. This article will make improvements to the Raspberry Pi AP based on the previous environme

We have explained in detail the Raspberry Pi control ultrasonic module ranging (http://www.cnblogs.com/yuemo/p/8888342.html) and ultrasonic control buzzer module audible (http://www.cnblogs.com/ yuemo/p/8906111.html).Today we'll see how to apply all two modules and make an anti-theft device.First look at the connection of each pin (requires seven mother-to-female DuPont line):Ultrasonic module:1.VCC: Connec

Do you have an idle mobile hard drive or Raspberry Pi? You can use these to create a cheap and low-energy NAS. The final effect is definitely not as good as the NAS for $500, such as those produced by Synology DiskStation. But you can build a low-energy network storage platform-and especially suitable for those who are tired of the National Security Agency's data

a more complex input with timing. Here are two points to note: The SetMode is in BCM mode, and the pin used is the same as the BCM number corresponding to the pin graph. You can also set the physical PIN number to use SetMode (GPIO). BOARD). The input/output mode is input when receiving data/status relative to host or Raspberry Pi, output i²c I²c can be a bus to

Is Raspberry Pi able to use the serial port? The answer is yes. The specific method is as follows: 1. The third, fourth, and fifth ports in the first row of Raspberry Pi are respectively, that is, ports 6, 8, and 10 are respectively, TX and RX, respectively, and connected to

purposes it is enough and has a very high price/performance ratio. The software for receiving and decoding S-mode signals provides a site interface based on Google maps and a local display that is not particularly needed. However, the addition of the Adafruit PITFT 3.5-inch display (124-5487) provides a concise overview of the "at-a-glance" aerial activity. In addition, the combination of the Raspberry Pi
