Detailed explanation of GPS NMEA-0183 Protocol NMEA AssociationThe purpose of this discussion is to establish a unified btcm (maritime radio technology commission) standard in different GPS (GPS) navigation devices by the National Oceanic Electronics Association (NMEA-National Marine ElectronicsA set of communication protocols developed by Associa-tion.

NMEA is the abbreviation of National Marine Electronics Association (National Maritime Electronics Association. The Association is a private institution dedicated to research on marine electronic devices and has developed NMEA standards for communication interfaces and protocols between GPS (GPS) electronic devices. NMEA-0183 protocol is currently the most widely

Source: NMEA Protocol host computer C #Some time ago wrote two with the NMEA protocol of the upper machine, here to do a summary and record. To share with you, but also for the future will not forget.NMEA protocol in general, relatively simple, is a relatively mature weather protocol.There are several main parameters and their formats: Wind speed and wind direction; Air temperature; Soil te

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positioning time, latitude, longitude, height, number of satellites used for positioning, and other

To launch two emulators on this machine, the information for this machine (PC) and simulator is as follows:As you can see, the IP address of the two simulator is exactly the same, so to realize the communication between the two simulators, using the emulator's IP address is impossible.Get Emulator Name:>ADB devicesList of devices attachedemulator-5554 Deviceemulator-5556 DeviceThe

IOS development-create a Simulator package for the iOS project for testing the iOS Simulator running on other computers (Creating an iOS Simulator Build) After the iOS program is developed, it is necessary to package the program and distribute it to everyone for testing. Generally, such tests are true machine tests, which are correct and necessary. There is only

The iOS Simulator is a helper tool that can be used when developing a program on the iOS platform under Mac. iOS Simulator is part of the Xcode, Xcode is Apple's own iOS development program that can be downloaded for free! The IOS Simulator is located in the/developer/platforms/iphonesimulator.platform/developer/applications folder. Typically, you do not need to

Xcode6 simulator path, xcode6 simulator pathAfter the release of Xcode6, there have been many changes and functional changes. I will not repeat them too much here. On WWDC, Apple has already talked about it and there are many articles on the Internet, here we will introduce some small things that are not easy to find, but very important.1.
