I found the non-extended php encryption method: There is an online method, which is not bad. It's okay to defend against Trojans. It's okay to protect the code. A simple decryption is written for eval. This principle is very useful. Write it down

Tkfiledialog If you want to open or save a file or to choose a directory using a filedialog you dont need to implement it on your own. the module tkfiledialog is just for you. in most cases the seven convenience funence provided by the module will

Original question: zoj 3674 http://acm.zju.edu.cn/onlinejudge/showProblem.do? Problemcode = 3674. It is not hard to understand the meaning of the question. It is easy to think of brute force, but you have no idea how to implement it. After reading

2. Use JNI to add service access interfaces at the application framework layer The application cannot directly access the Hal layer. The JNI layer needs to access the Hal module and provide APIs. You can directly provide interfaces, but it is

Write Process When the MCU performs write operations, it first sends the 7-bit address code of the device and the Write direction "0" (a total of 8 bits, that is, one byte ), after sending the message, the SDA line is released and 9th clock signals

IICVsSPIToday, in low-end digital communications applications, we are seen in IIC (inter-integrated circuit) and SPI (Serial peripheral Interface). The reason is that these two communication protocols are ideal for near- low-speed inter-chip

Data transfer format (1) byte Transfer and response Each byte must be an 8-bit length. During data transmission, the highest bit (MSB) is first transmitted. Each transmitted byte must follow one response bit (that is, a frame has nine digits ).

The following is a simple example:Only one host is set on the bus, and the host uses query read/writeMultiple slave machines are allowed on the bus, and the slave machine uses the hardware interruption function.*****************I started to use the

Clock stretching (stretching)Clock stretching pauses a transmission by pulling the SCL line down. The transfer continues until the SCL line is released high. Clock stretching is optional, in fact most slave devices do not include the SCL driver, so

I. About I2C The I2C (Inter-Integrated Circuit) bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. The main advantage of I2C bus is its simplicity and effectiveness. The simplicity is embodied in the simple wiring. There are only two lines of data cable (SCL) and clock line (SDA), and the control is simpl
