1, prepare the computer, GNSS module (SKG09A), EVB board, GPS antenna, Micro USB power cord, according to the "GNSS Skylab SKG12&09 EVB Instruction V02", the GNSS module (SKG09) welded on the EVB boardA) Correct power supply.
2, the current more famous gps module manufacturer is micro communications (vkelcom) connection test: ○ ⑦⑤⑤-⑧③⑤ ○ ②⑤ ⑤ ○ ②⑤ ○ ② How to use gps module Open the GPS module, use the Bluetooth search of the PC/ mobile phone installed with a navigation map, find the Bluetooth device on the GPS module, and pair. Set the Bluetooth port on your PC/ phone. Run the navigation map software on your PC/ phone, wait for the GPS module to search for satellite signals, and transmit Bluetooth data.
3, GPS module continuously output N through serial communication portMEA format positioning information and auxiliary information for the recipient to choose the application. There are three main types of GPS modules, namely the built-in GPS module without antenna, the built-in GPS module with ceramic antenna, and the integrated G-mouse external GPS module. It can realize the carrier's real-time positioning, timing, speed measurement and other functions, which is very suitable for large-scale application of the system.
4, greatly shorten the first positioning time. It should be noted that the time output by SKYLAB positioning module after positioning is UTC time, but the time obtained by the positioning module is actually GP/strong>, the assembly can not reach. Then the assembled battery capacity drops faster than the original battery, and the correct charging habits are more demanding. Wireless charging DEMO board I used this original for two years, although it was not used very carefully but felt that things were more reliable, and the capacity did not fall. Do not worry about the problem of explosion, if let the wireless charging DEMO board I said, the most terrible is the battery content leakage. It is recommended to use the original battery.
2, if you buy the Hong Kong version of the machine, JS to give you this Japanese version of the battery, basically assembled.2 look at the battery front reflectivity of the battery assembly used for the larger reflectivity of the battery can be compared to the special thanks to the news picture provided by Renjilian's Wang Five deluxe version of the black cloth bag with the original SONY label, and the stitching of the bag mouth is below the pocket, the assembly has no logo, And the suture is on the right.
3, it is best not to let things other than the protective film touch the screen, too easy to dirty, the mirror is colorless, it is not easy to distinguish, PSP is black, especially obvious. It is best to ask the merchant when buyingProtective film. It had at least half the charge when it was bought, enough to test the machine. It's probably best to get DEMODISK, it's not playable, but the graphics are fantastic. If the battery is installed, it cannot be taken out. Please think again if you want more batteries.
2, to achieve wireless ordering wireless charging DEMO board , you must have a wireless network, this is the premise. As for deployment, this different hotel pattern is different, so I still hope you can make the specific situation of your hotel clear, otherwise I really can't give you a suitable
3, and then buy a wireless module, is i2c bus or serial port control, so the driver will be much simpler, Then the purchase of wireless module with the demo module control program transplanted to qt, a separate implementationA class (this step is not difficult to be careful), and then make a order system interface program, call this class for communication.
