Hertz RFID Reader• A small circuit to read RFID badges operating at (EM4102)• This circuit is used here:coffee Tally sheet kaffee-strichlisteReading rfid-badges operating at + kHz is very easy. You just has to put a carrier (A-Z) into the air and has the badge do the work. The badge would do the ASK (amplitude Shift keying) and your only has to monitor the envelope of the carrier. This can is done by a simple diode rectifier.The carrier is generated b

As its name implies, high-performance stocks are the stocks of high-performance companies, but the definition of high-performance stocks is different at home and abroad. In China, investor balance The main indicators of high-performance stocks are earnings per share after tax and returns on net assets. In general, the profit after tax per share is in the middle of all listed companies After the company's listing, the net assets return rate of more than 10% of the stocks for three consecutive

bad prospects of the industry, or because of poor business, and some even into the loss ranks. Its stock in the market performance is depressed, the share price is low, the exchange is not active, the year-end dividend is also poor. Investors in considering the choice of these stocks, should have a higher risk awareness, avoid blindly follow the speculation.Blue-Chip -in the stock market, investors in the industry in which they occupy an important dominant position, excellent performance, trad

At present, the most common flash chip manufacturers are intel, SST, AMD, mxic, etc. Now we use a widely used 16 M byte flash chip as an example, compare their similarities and differences in performance and design. Intel's 16 M byte flash chip model is 28f160c3, SST is 39vf1601/1602, AMD is 29lv160d, mxic is 29lv160bt/BB. Operating voltage:The normal read, write, and erase voltages of these flash chips are 2.7 V-3.6 V, but Intel's 28f160c3 has a

Samsung intends to sell its Exynos chips to other handset makers to expand market share, foreign media digitimes reported. Samsung's sale of its own chips aims to increase the utilization of silicon wafer factories and increase their share of the global handset processor market, especially in the mid-market, according to people familiar with the situation.Why does Samsung want to sell

Optical Devices and chips: the key to improving Optical Communication in China With the development of cloud computing, Internet of Things, mobile Internet and other applications, the rapidly increasing data traffic puts forward higher and higher bandwidth requirements. In the past two years, the "Broadband China" strategy and the strategy of accelerating the construction of a powerful network nation have successively proposed that optical communicat

First, the development of software depends on the chip. If the chip has limited processing power, people will not develop a high-load software to run on the chip. For example, in the early days of the advent of smartphones, the load-bearing chip computing capacity is very limited, can only assume the call and basic entertainment activities, if the game manufacturers do not consider chip performance, the development of a high-definition quality, real-time rendering of 3D games, will inevitably be

SBB key Programmeris a universal key programming tool The can even make key even if all of the keys lost, because SBB interface is to insertTo the OBD diagnsotic socket to read chip data.Here takes a example of Toyota Smart Key 93C46 chip as an example to display how to remove EEPROM chips.No need install software, power by USB connection. 1. Remove eeprom 93c46 chips from IMMO ECUs and wire it to corresponding position on SBB V33 immobilizer key prog

A list of traffic card chips in major cities throughout the country to see if your hometown exists ......, Traffic card Abstract: With the continuous development of technology, traffic cards have become an indispensable part of public travel. The traffic card technology is constantly being upgraded, and each city uses different technologies. With the popularization of mobile devices, NFC also becomes more and more popular in traffic support. For examp

AMD chips are exposed to security vulnerabilities. Hackers can easily control network devices, AMD chips are exposed to security vulnerabilities. Hackers can easily control network devices. According to a study published by CTS Labs, an Israeli-based security company, the Advanced Micro Devices chip "has multiple major security vulnerabilities and manufacturer Backdoors that can be exploited ". AMD chi

It is very helpful to know about the switch chip. Here we mainly introduce the mainstream g/Gigabit mixed switch chips. According to the Linely group's market research report, Global Gigabit Ethernet will exceed the shipment of Fast Ethernet products this year. At present, the proportion of M switch shipments in the domestic market is still dominant. However, in line with the technological development trend, each switch chip company has launched a m t

Currently, norflash supports CFI or JEDEC specifications. Based on these specifications, some chip parameters can be automatically detected and read/write, therefore, uClinux separately stores the driver implementations of these specifications in the MTD/chips directory. That is to say, this directory stores the general driver code of the chip. The Code itself will not actively detect the existence of the chip. It just registers a driver for other mod
