Build your own 256 spi programmer

ISP Flash Microcontroller Programmer Ver 3.0
Introduction
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.
Hardware
Figure 1 shows the circuit diagram of the in-system programmer interface, the power to the interface is provided by the target system. The 74HCT541 ic isolate and buffer the parallel port signals. It is necessary to use the HCT type ic in order to make sure the programmer should work with 3v type parallel port.

Figure 2 shows the circuit diagram of the stand-alone spi programmer, the power to the interface is provided by the PC USB port which can supply a max of 100mA current. Get a cheap USB cable, cut the
cable other end connector and attach a crimp shell connector to this end, red wire is 5v and black is 0v.



The printer port buffer interface is same as shown in figure 1. For the u-controller a 40 pin ZIF socket can
be used.
This programmer circuit can be use to program the 89S series devices and the AVR series devices which
are pin compatible to 8051, like 90S8515. For other AVR series devices the user can make an adapter
board for 20, 28 and 40 pin devices. The pin numbers shown in brackets correspond to PC parallel port
connector.

Software
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.

I FOUND THIS ON ANOTHER FORUM SO CREDIT GO'S TO Gazbelfast

DONT KNOW IF IT WIRK'S BUT GOING TO GIVE IT A GO.

IF ANY1 WANT'S TO TRI IT PLEASE LET ME KNOW HOW YOU GET ON AND ILL DO THE SAME......

I wouldn't mind giving this a shot but I have one question. Is there a way to make your own 8-way SOIC clip?

[kamcom]

yeah use a clothes peg! and a few wires !

[kamcom]

for the time and effort you can buy a usb one off flee bay for £20

did u see the date i postedit lol

[jack08]

parts list link dead can anyone give us info parts i nered please

Will this programmer do the job thanks

USB Programmer for 25XXX SPI EEPROM - ZIF, ISP on eBay (end time 01-Mar-10 23:19:21 GMT)

Sorry if I poat in wrong place. Or maybe should have started my own.

i wouldnt go for that one. you want one with a parallel connector.

the size chips doesnt look to good either. the mx in a 256 is 2mb.

does anyone know what the 16 legged chip is in a ambit 300?

[edgard22]

It looks good, has anyone tried this?

I didn't build this one as I bought one but I don't see why it wouldn't work as the SPI Programmers you can buy are constructed in the same way .
