You do not need to redeploy the database file when debugging a simulator in mobile development.
Test the product PDA approval function with the simulator provided by vs2005
Use Windows Mobile 2005 se Chinese simulator in visual studion 2003 Professional
In Visual Studio 2005, use ActiveSync to synchronize simulators (Windows Mobile 5.0 for smartphone)

, start with the following:
1,Whether the serial number is correct.
2,If the version is correct, the project file opened in 7.30b cannot be opened in 7.20h.
3,Try not to use the Chinese path.
4,The ZigBee protocol stack folder must be placed in the IAR installation disc root directory.
5,Check whether the current compiled folder has read and write permissions.
6,Whether the version used is limited to version.

When I first learned that Qt was learning MFC, it was sad to write the MFC program.
One-time Qt compilation and multiple compilation. On windows or linux, you only need to change the compiler to OK, and the Code does not need to be changed.
By writing a program on linux, I involved the program on the arm board and reading the information sent from
I have been here for more than half a year. During this time, I have gained a lot of knowledge and a wonderful life.
At work, we first make detailed arrangements for every day's work, and check the completion of the previous week and the arrangements for the next week every Monday. At the beginning, I was familiar with the development environment, mainly the development board of 6410. I checked the user documentation and the chip manual to test the interface performance of the first version of
algorithm for communications between all nodes. It is a fully supported multi-hop, AD -Protocols for the Hoc and mesh networks. In the xmesh network, all nodes communicate over the wireless network, and the computer or client can obtain data from the sensor network by forwarding information to the base station. The forwarding function effectively increases wireless communication distance and reduces energy overhead during data transmission. Generally, these nodes run in a low-power mode and hav

Of course, you can also set your own personalized templates, or even set a time for switching between modes.The additional hue lamp is $59, and the price of the bridge device connecting to the router is $50.If your home already has your own lighting system, Philips hue lights also provideTo

Compared with the low-cost platform, this technology platform mainly consists of application processors (such as arm10, arm10, and other high-performance embedded processors) and wireless communication modules. This technical solution has independent memory units (SDRAM) and storage units (nandflash). Application Processors may integrate complex multimedia processing functions such as im

WiFi is a technology that allows computers, handheld devices such as PDAs and mobile phones to be connected wirelessly to each other. Wi-Fi is a wireless network communication technology brand, held by the Wi-Fi Alliance (wi-fialliance). The aim is to improve based on IEEE802. 11 interoperability between standard wireless network products. At present, the average p
