However, if the system returns a random value when outputting an element greater than a [5], you cannot use an element that exceeds the initial value.
5. Because ADS does not support printf, it is difficult for us to debug it. We can use Serial Output instead of printf for debugging.
6. Use the or operation to set a position to 1, and the other BITs remain unchanged.
Eg: pinsel0 | = 0x00000005; // set the Serial Port Pin
to different CPUs according to certain rules, in this way, the sine curve cannot be drawn. Therefore, we must first determine whether the user's computer has multiple CPUs.
Use the getsysteminfo function to obtain system information and pass the system_info structure to the function. A member dwnumberofprocessors in the structure indicates the number of processors. If the value is greater than or equal to 2, multiple processors exist. We need to use the setprocessaffinitymask function to set th
Due to machine performance problems, many services are disabled and need to be enabled again when needed. In this way, it is troublesome to open the service management or cmd command every time, and the tool is displayed on the desktop by yourself;

If Keil arm is used, vpbdiv = 0x00000000 is automatically generated in startup. S, which leads to fpclk dividing by 4. The baud rate is reduced by four times. The default value of startup. s in Keil is as follows .; // ; // ; // ; // ; // ; // ; // ; // ; // ; // ; // Vpbdiv_setup equ 0vpbdiv_val equ 0x00000000 we will change it:
Vpbdiv_setup equ 1
Vpbdiv_val equ 0x00000001
Solve the problem.

Specifying device types
Each device object hasDevice Type, Which is stored inDevicetypeMember of its device_object structure. The device type represents the type of underlying hardware for the driver.
Every kernel-mode driver that creates a device object must specify an appropriate device type value when callingIocreatedevice.IocreatedeviceRoutine uses the supplied device type to initializeDevicetypeMember of the device_object structure.
The system defines the following device type values, liste
Well, we're officially starting with a step-by-step process to write shellcode, combining the previous example program, to write a shellcode that opens a new shell.Before writing, it is particularly useful to introduce some techniques for writing shellcode.Shellcode Writing SkillsHow to avoid 0 bytesShellcode is usually caused by a string function such as strcpy/sprintf to cause overflow, so the shellcode injected through it cannot appear 0 bytes.

It is well known that, under ARM architecture, function parameters are passed through R0~R4 registers, but if there are more than four parameters, it is necessary to use the stack.
Here is an example to illustrate.
int func (int a1, int a2, int a3, int A4, int a5, int a6)
{return a1 + A2 + A3
+ A4 + a5;
}
int main (void)
{
func (1, 2, 3, 4, 5, 6);
return 0;
}The main () is compiled as follows:
0x00010418 This time (executes to the point where the arrow points), the stack's status is as

The end of the article I made a picture, a look at it, this problem on the Internet to speak a lot, but did not put the problem through.
First, the conceptAlignment is related to the location of the data in memory. If the memory address of a variable is exactly the number of integers in its length, he is called a natural alignment. For example, under the 32-bit CPU, assuming that an integer variable has an address of 0x00000
