Design of universal USB Interface Module Based on AVR Microcontroller [Date:2008-6-25] Source:China Power GridAuthor:Zhang Hong, Dong xiucheng [Font: large, medium, and small] 1 Introduction USB interfaces have become one of the main ways for peripherals to communicate with PCs due to their fast data transmission, simple connection, easy scalability, and support for hot swapping. With the development of embedded systems, embedded microprocessor needs to

advantages mean that arm has a wider application scope than AVR. Therefore, if "We use AVR in Middle School" is correct, we should use arm in university.We can see that at91m55800a Based on the ARM core of ATMEL includes a lot of AVR peripherals, but still lacks Twi/I2C, variable gain ADC, EEPROM and other useful components. However, there is no doubt that arm's external expansion and peripherals are more

1. Introduction of ADCThe ADC supports up to 14-bit analog-to-digital conversions with up to 12 digits of significant digits. It includes an analog multiplexer with up to 8 individually configurable channels and a reference voltage generator. The conversion results are written to the memory via DMA. It also has several operating modes.The main features of the ADC are as follows:Optional decimation rate, whi

of the professional manufacturers of microprocessor production. This is a low power, high Performance: 8-bit, 4-kb flash memory microcontroller. Is a high density non-volatile memory technology and MCS-51TM with industry standards The Instruction Set and pins are compatible. This is a classic MCU of ATMEL, probably because it is too old to be Some more powerful siblings are beyond, but this is still the hottest MCU! Main features and advantages: 1. c

S5PV210 Development Series One development environment and startup modeChess Boy 1048272975The arm core is widely used in various fields, including ARM7, ARM9, ARM11, Cortex-m, and Cortex-a, for its high performance, low power consumption and low cost. Many semiconductor vendors such as NXP, Freescale, Atmel, Samsung, TI, etc. have designed their own general-purpose processors based on arm cores, from low-cost control processors to high-performance ap

∑– analog-to-digital converter (ADC)1. OverviewIn recent years, with the improvement of VLSI manufacturing level, sigma-Delta analog-to-digital converter is widely used for its high resolution , Good linearity and low cost . Sigma-Delta Analog-to-digital converters the proposal was already made in the 1960s, however, until recently, this process was not feasible in the production of devices commercially. Today, with the maturity of 1 micron technology

Quickly launch new cloud and mobile applications using the application delivery controller as a service The Application Delivery controller (ADC) evolved from the basic server load Balancing functional unit to integrate fully with cloud workflows and preconfigured systems, helping users quickly roll out new applications to mobile workers, increasing end-user satisfaction, and reducing application deployment time and cost.

MCU is a typical digital system, digital system can only be a digital signal processing input, its output signal is also digital. However, many quantities in industry or life are analog, which can be converted to the corresponding voltage, current and other analog quantities by the sensor. In order to realize the measurement, operation and control of the digital system, it is necessary to convert the analog quantity and the digital quantity into one another.The basic concept of A/D and D/aThe A/

, 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
