1. attribute: HP: affects the life ability (MAGIC) of a person: affects the physical, magic attack power, the restoration effect of the rod, and the hit rate of the rod. Skill: affects the hit rate, which is mandatory. Speed: affects the back-to-back rate and attack speed. Fortunately, the hit rate and return avoidance rate are affected, which are mandatory, as well as the desert treasure rate and the anti-

3. Add Object Attributes1) You can add attributes to the "attribute" option tag in the preceding window, as shown in.
Note:The "add attribute" and "reuse existing data items" functions in the data item are related to the unique code of the data item in the model and the allow reuse option.The P column indicates whether the property is the primary identifier; the D column indicates whether t
implies a delay (DEFER). Similarly, you can use alter system to enable or delay the ALTERNATE destination at runtime.
You can increase the number of archiving destinations to reduce the number of active ALTERNATE archiving destinations.
When the archive destination fails, the ALTERNATE destination is enabled for the next archive operation. The ALTERNATE destination cannot be enabled during the archive operation. Because the REOPEN attribute requires you to re-read the blocks processed by the de

Dialogs are tools that provide interactive patterns for the man-machine conversation. The application passes the dialog box, or provides information to the user, or obtains information from the user. A dialog box is a temporary window in which you can place controls to get user input. In swing, there are two dialog box classes, which are the JDialog class and the Joptionpane class. The JDialog class provides constructs and manages common dialog boxes, and the Joptionpane class provides many easy
memory and data storage, that is, the two types of memory are located in different logical spaces. The microcontroller or microprocessor that conforms to this architecture, it is called the Harvard architecture. For example, the earliest popular Single Chip Microcomputer in the domestic market ---- Intel company developed and manufactured MCS-51 series single chip microcomputer, micro Star (microchip) Company's PIC Series single chip microcomputer, Y

(2) Mosi-master device data input, output from device data
(3) sck-clock signal generated by the master device
(4) CS-enable signals from the master device
Among them, CS is to control whether the chip is selected, that is, only when the chip selection signal is a pre-defined enable signal (high potential or low potential), this chip operation is effective. This allows connecting multiple SPI devices on the same bus.
I have introduced so much about the SPI bus theory.
channel automatically controls the Write Start address and length based on three registers. To send data frames to Ethernet, the DSP only needs to set the TXP of the control register CR to 1. RTL8019AS will automatically complete data verification and send.3. TCP/IP protocol implementationDue to the limitation of processing resources and real-time requirements on embedded hardware, the implementation of TCP/IP protocol is different from that on the general computer, requiring as little storage

or 10 V above is the on-voltage of the commonly used MOS tube. Of course, there must be a certain margin during the design. The higher the voltage, the faster the conduction speed, and the smaller the conduction resistance. At present, MOS with lower conduction voltage are also used in different fields, but in 12 V automotive electronic systems, it is enough to conduct 4 V.For more information about the driving circuit and loss of MOS, see the Microchip
Intel: the Key to defending against cyberattacks is "golden hour" and Intel hourAccording to a new report, when enterprises suffer a network attack, they will find and respond to the attack within an hour.In a report released on Monday morning, Intel, the microchip giant, claims that "golden hour" is the most critical period for enterprises to avoid major losses in the face of network attacks. However, attacked enterprises often do not realize that th

As long as enough gate circuits are connected in the right way, any calculation can be performed. The most important circuit element today is the transistor. Now the logic gate c
