, various memory cards, and MP3 players. due to technological differences, NAND Flash has a larger storage capacity than nor flash, and cheap. However, there are also disadvantages: you cannot directly run programs with addressing, and you can only store data. In addition, NAND Flash is prone to bad areas, so verification algorithms are required. In the handheld computer, you must use NAND Flash to store data and programs, but nor flash must be enable

time. 8. Use personal firewalls and anti-virus software on the WLAN client to prevent damage to client attacks. As mentioned above, the security of WLAN can be provided by the security measures of WLAN itself, but also by using some dedicated security products, at the same time, a set of reasonable WLAN dedicated security management specifications and systems are required. The following describes some security products that can be used for WLAN. After analyzing the security of Wireless LAN, we

For the application of the HART protocol, we will introduce the hand-held HART communicator. What are the characteristics of the application of this product? Let's introduce it to you. Through the picture, we can see the appearance of this product, then the model of this product is ESC-375H. It features: The HART375C handheld device is a handheld device that provides a public communication interface for All

appliances has also contributed to the development of embedded software. Color TV, DCD, mobile phones, MP3/MP4, handheld computers, and automobiles are all potential information appliances. Unlike general operating systems and databases, the information and electric appliance platform does not have a monopoly on the market of foreign software vendors. This field has become a breakthrough in China's software industry.Embedded systems are designed for

By defining style sheet rules with different media types and conditions, media queries allow CSS to work more precisely on different media types and different conditions for the same media. Most media features of media queries accept Min and Max to express "greater than or equal to" and "small and or equal". Such as: Width will have min-width and max-width media queries can be used in CSS @media and @import rules, can also be used in HTML and XML. With this tag property, we can easily achieve a

button, roll back the stack to allow the user to return a fragment event (navigation backward ). When the fragment you add is part of the activity layout, it resides in a ViewGroup of the activity's view structure, and fragment defines its own layout. You can define fragment in the activity layout file to insert it into your activity, like Or add it to an existing ViewGroup through the code in your application. However, a fragment does not have to be part of the activity layout. You can a

Bitmap for a handheld device that uses gray display, you can use MS paint to select white, black, light gray, and dark gray entries from the palette (typically the first two colors of the first and second rows) to build a bitmap. Save it as a 16-color image, and then use 2bit tool to convert it into a two-bit bitmap. C.
