The doorbell's third revolution: Wireless doorbell without battery -the world's greenest and most energy-efficient wireless doorbell:augreener Wireless DoorbellThe earliest doorbell is wired, requires special cabling, installation and maintenance costs are high. With the development of wireless technology, wireless doorbell was born. Wireless
The doorbell allows the visitor to reach for the purpose of knocking at the door or shouting, and also avoids harassing the neighbours, while the interviewee can be prompted by beautiful and easy music to welcome the visitors to the door and greet them without neglecting the guests because they cannot hear them. Let's talk about how to choose a doorbell:According to different circumstances, optional cable doorbell

Doorbell's interrupt-to-core mechanism is implemented by the DOORBELLX_ICRRX register, with a total of eight ICRR registers.
When doorbell packets is received by the SRIO peripheral, Theseicrrs Routedoorbell interrupt requests (indicated in the ISCR register) from T He associated doorbell Icsrto user-selected interruptdestinations. Each of the four doorbells can is mapped to these registers.

VMware11 Install Mac OS X10 prompt for unrecoverable errors (vcpu-0) What to do? This article describes in detail how to troubleshoot VMware11 install Mac OS X10 prompts for unrecoverable errors.
Error Tip:
"VMware Workstation Unrecoverable Error: (vcpu-0) vcpu-0:vereify vmcore/vmm/main/physmem_monitor.c.1123 log file is located in E:os Xvmware.log." You can ask for support. To collect data
It is well known that VMware is a well-known virtual machine that can create multiple virtual systems in a system with VMware virtual machines, whether it is to install a Mac system or a Windows X system, and VMware is easy to implement, with the recent small series installing Mac OS under VMware virtual machines X10 Tip Unrecoverable Error (vcpu-0), how should we deal with this problem? The following small series for you to provide a solution to such

TIPS:1. It is best to add wairforsingleobject when writing network shellcode again.2. Do not forget exitprocess to avoid many program errors.3. Do not have 0a after the code passes xor99, because in IE overflow, 0a is converted to 0d0a, which will be shortened during string copy.Let's write this! I hope you will be inspired!

The single-chip Interrupt System Concept: What is interrupt, we introduce it from a routine in life. When you were reading a book at home, the phone suddenly rang. You put down the book, answered the phone, talked to the caller, put down the phone, and came back to continue reading your book. This is the phenomenon of "interruption" in life, that is, the normal working process is interrupted by external events. The interruption in our daily life is also very beneficial for us to learn the interr
