一：简介

这款编程器是由国外电子网推出的第一个版本V1.1，简单易用是这款编程器的特点。采用标准LPT系列接口，不需要任何其他的组件。可以读写常用的51系列单片机，自带处理器，和电脑并口连接，读写速度快，软件只能运行在WIN9x。

二：编程器支持的器件：

本编程器所支持的ATMEL－89C系列MCU的器件列表，见下面。

AT89C51

AT89C52

AT89C55

AT89C1051

AT89C1051U

AT89C2051

AT89C4051

Note:  For 20 pin devices a simple interface adapter is required. （20PIN的器件需要另外的适配器）

三：硬件简介

下图所示是ATMEL－89C系列FLASH编程器V1.1的原理图，采用标准的LPT并口连接到PC机。U1用于控制PC与编程器之间的数据传输方向，U3低地址字节锁存器，U4高地址字节锁存器，U2是器件编程控制信号的通用控制IC。电源供电是由U6控制和产生的。U5用于提供被编程器件所需的电压，等等。

Adjustment procedure for P1 and P2 variables.
1. First adjust P1 to get the 12.75V at the output of LM317 regulator. Make sure transistor T4 is off or 
    temporarily connect the T4 base to ground.
2. Now temporarily short the collector of transistor T4 to ground.
3. Adjust P2 to get the 12.0V at the output of LM317 regulator.

四：PCB板

The prototype board may be built using universal PCB with point-to-point wiring. If you want to make a PCB, get the PCBs.zip file which contains the printer files *.PRN for HP Laser printer and the plotter files *.PLT for the HP Pen plotter. Figure 3 shows the component layout of the programmer pcb.

五：软件

PGM89.exefile is used to run the programmer. This is a DOS program which can also be used in Windows 95 and 98 msdos window but not in windows NT. The main screen of the program is shown in figure 4.

Following are the main features of this software,

Read and Write Intel Hex File

Read Chip info

Verify from hex file

Program Lock Bits

Fill buffer & Display buffer

Parallel Port selection LPT1, 2 & 3

Remember the previous settings of the programmer
 

Note: In order to insure safe insertion & removal of the u-controller from programmer zif socket make sure programmer power supply is turned on before starting the program and the red LED D2 must be turned off.
