A. EV-51 series SCM experiment board (optional a serial port or USB port directly download program)
This experiment used is STC company board of the production of the STC89C52RC microcontroller, it is a very high price of a single-chip microcomputer, it is fully compatible with the ATMEL company 51 SCM, in addition it oneself also has many characteristics, such as: can't decrypt, low power consumption, high speed, high reliability, high anti-static, strong anti-interference, etc.

Second STC company single-chip internal resources ATMEL company than the single-chip microcomputer to rich, it has more than 1280 bytes of internal an SRAM, 8-64 K bytes of internal program memory, 2-8 K bytes of the ISP guide code, except for P0-P3 more outlets to mp4 mouth (PLCC packaging), in the way of take 8 eight AD (AD series), piece of EEPROM, bring in machine watchdog, double cabin data of Pointers. At present the company microcomputer in the STC domestic market share grows day by day, the STC microcontroller EV series microcontroller can be fully development board as all kinds of 51 SCM experiment board, written in assembly language or C language of the programming. When using the company's single-chip microcomputer, STC directly with product package with serial line will development board and computer serial connected, according to download operation tutorial and chip STC downloadable program, and download speed faster than other download tools.

2. EV-51 experiment board basic configuration
1, 89 C52, support USB ports or serial two download program ways, namely you don't need to buy single-chip microcomputer and write the can burn to write programs to your film view your program status.
2, 6 a digital tube (do dynamic scanning and static show trials).
3, eight LED light emitting diode (do). The water light
4, MAX232 chip RS232 communication interface (as with computer newsletter interface also can be used as a download a program interface chip STC)
5, USB power supply system, directly interpolated received computer USB port can provide power supply, do not need to pick up another dc power supply.
6, do the buzzer (SCM) voice
7, ADC0804 chip (do modulus of transforming the experiment).
8, DAC0832 chip (do analog-to-digital conversion experiment)
9, PDIUSBD12 chip (USB device development, such as single chip reading and writing U disk, homemade U disk, homemade MP3, etc, but also by the chip to make the computer chip and transmit data).
10, USB turn directly by computer chips, serial ports USB port download program to microcontroller,
11, the temperature sensor DS18B20, (try to grasp the operation can be personally chip after program had at the time temperature)
12, AT24C02 external EEPROM chip (IIC bus components experiment)
13, characters, LCD 1602 interface. (can show two lines of characters)

14, graphics LCD 12864 interface (can show any Chinese characters and graphics)
14, 4 * 4 matrix keyboard plus four independent keyboard (keyboard test).
15 and single-chip microcomputer 32 IO mouth all derivation, convenient for free expansion. His
16, the locking device, very convenient installation and discharge of the chips take
16, most of the component is enclosed, effective patch save system space. The choice of components with software choose the jump line, no jump pick, have extremely strong comprehensive system.
17, CD contains this experiment board all routines. Give wei Gospel simulation software, light 51 pro download software, STC microcontroller program download software, such as KEIL51 circuit diagram, and all the board detailed course, the download tutorials use, etc.

3. Bring their own online simulation function

EV series can be directly mounted online learning board simulation chip, the user can SST89E564RD don't have to pay to buy the expensive simulators, the chip in experiment, and directly online one step, commissioning, at full speed.
The simulation of the chip can realize the function: chip computer and experimental board between real KEIL software with online commissioning, connect the simulation can be in software testing model of single step instructions executed, can be set breakpoints, etc. Each executive an instruction can see the experiment board operation state, and may at any time to check all the value of the variable, is very helpful for beginners. If you don't use chip and direct simulation using board microcontroller commissioning program can only be instructions executed at full speed, through the experiment phenomenon to modify the program to board, download again. EV using simulation study board series function as the only need to transform the board single-chip pulled out, press on simulation according to the disc chip that can be realized the simulation test. Tutorial (with standard components including simulation chip, users don't need additional money)

Four characteristics.
· programmer, experimental board, and write device, simulators and four, quality assurance, stable performance, with a base for the motherboard, the use of safe, rich resources board, the jumper straightforward, easy to learn, provide abundant experiments routines, including assembly and C source code by the public, the programming software, performance guarantees with 40 Pin, outside enlarge interface with six Pin, ISP download link head, do the ISP download line use

Laptop use EV plan: many users want to use notebook to connect the board, and many notebooks are no serial ports, EV microcontroller learning board can use directly USB ports, download a program by the user interface connection after download USB computer, computer prompts new hardware, installation CD found in turn serial driver USB and use directly.

EV single chip board with PHILIP company learning the USB1.0 communications chip PDIUSBD12, the chip can not only as a USB host also can be used as a USB device used in this experiment, including the chip board CD all the drivers, firmware program comes with detailed annotated, system configuration files, using VC write computer through the USB port and single-chip microcomputer test procedures, all the communications of the source code to all users. Development of a USB have experience greatly, USB chip firmware (which is also control program of the CPU source program) and the writing of the driver is the main obstacle to hinder the novice.And EV microcontroller learning board includes all the source code these, as long as you can understand the source code (written in C language), you can easily into the USB development to the gate. Doing their own USB equipment, you need not from the floor, just need to write code in procedures, we provide to you on revising, can easily finish your own development project. EV single chip board is a set of learning will let you know the Philips PDISUBD12 or all the suite, potential D12 through this suite we can know how it works, and at the same time we could further knows how to existing devices converted into a USB device.
And now in the market generally sales of the PDISUBD12 Philips only the development of your board of hundreds of yuan, this experiment on the board as one of the only D12 small a function for the user study
