Objective-

 

To make IC programmer or burner kit

 

Introduction:

In this project we will make 8051 proframmer. It will use

This ISP Programmer can be used either for  in-system  programming  or  as a  stand-alone spi programmer for  Atmel   ISP   programmable   devices.  The   programming   interface   is   compatible   to   STK200   ISP programmer hardware so  the users of STK200 can also use the software which can program both the 8051 and AVR series devices.

The ISP-3v0.zip  file contains the main program and the i/o port driver for windows  2000 & XP. Place all files  in the same folder, for win-95/98 use  the  "ISP-Pgm3v0.exe" file, for win-2000 & XP use the "ISP-XP.bat" file. The main screen view of the program is shown in figure 3.

 

Also   make   sure   do   not   program    the    RSTDISBL    fuse   in   ATmega8,   ATtiny26  and  ATtiny2313 otherwise  further  spi  programming  is  disable  and  you  will  need  a  parallel  programmer  to  enable  the

 spi  programming.  For  the  fuses setting consult the datasheet of  the respective device.

 

For  the  auto  hardware  detection  it  is  necessary  to short pin 2 and 12 of DB25 connector, otherwise the

 software uses the default parallel port i.e. LPT1.

 

I  have  only  included  the devices  which I have  in hand, and verified their correct programming, when I will

 get the other devices the software will be updated.

 

Following are the main features of this software,

 Read and write the Intel Hex file

 Read signature, lock and fuse bits

 Clear and Fill memory buffer

 Verify with memory buffer

 Reload current Hex file

 Display buffer checksum

 Program selected lock bits & fuses

 Auto detection of hardware

 

 

Note:

 

The  memory  buffer  contains  both  the  code  data  and  the   eeprom  data  for  the   devices  which have

 eeprom  memory. The  eeprom  memory  address  in   buffer  is   started   after  the  code  memory,  so it  is

 necessary the hex file should contains  the eeprom start address after the end of code memory last address

 i.e. for 90S2313 the start address for eeprom memory is 0x800.

 

The  software   does   not    provide    the     erase    command     because    this    function    is    performed

 automatically  during  device programming.  If  you are  required to erase the controller,  first  use  the  clear

 buffer command then program the controller, this will erase the controller and also set the AVR device fuses

 to default setting.
