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
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.
