Author:■ Zheng Xuyang, Xi'an University of electronic science and technology, Li Bingbing, Huang Xinping
Abstract:This paper introduces the principle of multi-master communication simulating I2C bus, and proposes a new implementation method. This method uses delayed receiving comparison to implement arbitration, so that common Microcontroller (MCU) without I2C interfaces can implement multi-master communication that si

to him. This is something big companies can't do. He has a strong planning year. Small companies rely on judgment, experience, ability, vision, and scientific experience to take risks in inventory. If they do not have a sense of accuracy, the capital chain is broken. Therefore, small companies generally do not charge fees, small companies rely on fast conversion.
The development of this industry has its own characteristics. In the past, it was a fixed development and is now a sector-shaped deve
I2C bus principle and application example
The I2C (Inter-Integrated Circuit) bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. The I2C bus was originally developed for audio and video devices in 1980s and is now mainly used in server management, including communication in the status of a single component. For example, the administrator can query each component to manage system
(Inter-Integrated Circuit) bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. The I2C bus is a serial bus consisting of the SDA data line and the clock SCL, which can send and receive data. Various controlled Circuits are connected in parallel to this bus, and each circuit and module has a unique address. The CPU sends an address code for site selection, that is, the circuit to be controlled i
related to HDMI IIS and codecs ", I was a bit dumpfounded, and I always thought it was wrong, but I couldn't remember it. I found a channel on the schematic and couldn't find it. I finally found myself sb. The video and audio are transmitted on the same data line. I still felt right. I still had a TV, and the code was right.
Let's take a look at the figure. It is clear that the voice is transmitted from there:

Joysticks: handle. Even if you drive the handle in Linux, it doesn't make much sense, and there are too few games.

, the data interface subclass requires a periodic (isochronous) terminal point whose direction is input (in) and a periodic terminal point whose direction is output (out. The control terminal points are mainly used for enumeration of USB devices and communication between the baud rate and data type (Data bit, stop bit, and start bit) of virtual serial ports. The non-synchronous terminal point in the output direction is used for the host to send data to the slave device (slave), which is equivale
, the application of the field bus can be put into full play, and will provide a richer basis for the improvement of the field bus. The controller can (Controller aeranetwork) came into being in this context. As can is widely used and promoted in more and more different fields, the standardization of communication packets in various application fields is required. Therefore, in September 1991, PHILIPS semiconductors formulated and released the can tec

Experts once again reminded consumers that the CFL shunt in LCD backlight lighting components may still carry a high pressure of V (although it is a micro-current) after being shut down for a certain period of time, even if there is no harm to the human body, for LCD display, non-professional personnel may cause new component faults if they are not properly handled.

EEPROM, when the computer is used, it can be re-programmed frequently. the lifetime of the EEPROM is an important design consideration parameter. One special form of EEPROM is flash memory. Its application is usually the voltage in the PC to erase and re-program.EEPROM, which is generally used for plug-and-play ). It is often used in interface cards to store hardware configuration data. It is also commonly used in "Hardware locks" to prevent unauthorized copying of software.
