Use the miniUSB line to link the board and the computer, and then under "My Computer" there will be a beaglebone getting started disk, under this directory found a folder named "Drivers", Under this folder to find the corresponding operating system of the program, installation. If there is a prompt to trust the manufacturer's driver of a kind of prompt box, all choose Trust (do not trust the words can not play ....) ) until the prompt driver installat

who have to do rookie, rookie not scary, afraid of is no one to guide the direction of progress! This series of articles will describe the basic use of each function module of BBB. There are too few BBB data in Chinese now, they are collected from all corners of the internet in the world, learned, personally tested experience summary. To share with you, I hope everyone (especially beginners) in the BBB to get started on the road to some smooth!I will be here to update the list of articles at any

don't add this resistor. When connecting, of course, all power is turned off. On the relay control side, the 3.3v,gnd of the BBB is connected to the gnd,in signal of the BBB to connect the BBB p9_13 (GPIO number 31). Note, however, that the circuit connection on the other side of the relay must be followed by the manufacturer's instructions. In general, the middle of the relay is connected to the FireWire (positive), the other two ports are normally open negative and normally closed negative.

This luatool actually helps me manipulate the NODEMCU command and convert the code. Run-time plus –v parameter you'll know what it's for. Usage is Python luatool.py–p/dev/ttyo2–b 9600–f xxx.lua–v -P is the serial port,-B is the baud,-f is the local code file,-V is the display process. It's obvious that it jus

clear points:A Controls the Gpioport output of the BBB board by 0 or 1. The value of the value file under the corresponding gpioxxx under the/sys/class/gpio folder is changed.B Change the Gpioport input and output mode is to change the/sys/class/gpio folder under the corresponding gpioxxx under the direction file value is in or outC The entire BBB board hardware Device control by reading and writing the corresponding Linux device virtual files, so learning BBB board file Structure system is ver

Why use the advantages of Beaglebone BeagleboneCurrently, a typical microcontroller-based board is priced at about 120 yuan, while Beaglebone Black is priced at about 330 yuan. What else did you get for the extra money besides the more powerful processors?1.2.1 Built-in networkThe built-in network is not just the onboard Ethernet interface, but also all the avail
