You need a PC with a parallelport (Printerport) and
DOS or Win9X. Win NT does not work.
1)Build the SP12_cable (see eagle attachment)
2)Download flash program SP12v0_7.exe
from "http://www.xs4all.nl/~sbolt/e-spider_prog.html
3)download Rom-Image from
"www.jhansmann.de\work\eeg\eeg_files\RS232EEG_release010226\AT90S4433 firmware\firmware rom image\firmware_EEG02_001214.rom"
4) initialize PC- parallelport with:
sp12.exe -i
5) connect SP12cable with PC-parallelport and RS232EEG 2x3 pinhead programming connector
6) activate power supply for RS232EEG
7) burn ROM-image:
sp12.exe -wpfC firmware_EEG02_001214.rom -T1
8) _DANGER_ : disconnect the SP12cable before connecting the EEG to a test subject !!!!
(That is important because the SP12cable crosses the opto-isolator and connects PC-ground
to EEG-Ground)
>Looks like it's not easly avalable.
I have bought some AT90S4433 at
www.segor.de
Perhaps you can look at the ATMEL website to see where the nearest dealer is located.
Regards,
Joerg
