[7 of iOS and EV3 hybrid robot programming series] EV3 and iosev3 are controlled through Bluetooth1 Preface in my previous blogs in this series, I found that without iOS jailbreak, I could not use Bluetooth to control EV3 and write a Commander-like program. However, recent studies with Netizens found that the use of External Accessory to achieve Bluetooth transmi

LEJOS+EV3+WIN7 Environment Construction1, build the Java development environmentDevelopment packages that require JDK (note that lejos0.9.0 only supports jdk1.7 's development package, which is not compatible with the pro-Test jdk1.8). For http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html. If the connection address is invalid, please use the "JDK" of the Niang. The installation process is omitted ...Setting the JDK en

in the previous article, we discussed the possibilities of robot development after the combination of iOS and EV3. So, do you want to get together and hacking? to be able to complete the project I am going to talk about next. We need to make the following preparations:1. A Mac performs more than 3 operating systems on Mac OS X 10.9.2, Xcode6.This is the development tool for iOS on Mac. We'll use Xcode to write all the project programs.3, one or two iO

addition, in Netscape, the second click is always handled separately before DblClick. Anyway, the warning box is very dangerous here. So make sure your click and DblClick are well separated to avoid a lot of complicated things. Mousemove The MouseMove event works well, but it is important to note that it may require a lot of system resources to handle all the MouseMove events. When the user moves the mouse over a pixel, the mousemove is triggered once. Even if nothing happens, long and comple

Problems with LEGO Software Installation The Lego robot EV3, which was bought some time ago, has never programmed it, but the daughter has assembled it, so no software has been installed on the PC. On Saturday, after setting up a model, my daughter needs to program it. Therefore, she needs to install programming software on the PC before installing the software from the Lego website. Since WINDOWS is installed with WINDOWS 600 64-bit, the download

Every Tuesday afternoon is an experimental high school school-based class time, I opened this year's school-based class is a robot.Speaking of robots, I have already opened the last semester, with some teaching experience, of course, this semester has laid a good foundation. The difference is that the robot used in the school period is the middle Ming, the class location in the computer room, and this semester with the robot is Lego the latest EV3, cl
