Thank you for help me.... http://www.8051projects.net/forum-t6067.html 2009-01-07T21:33:32-08:00 Ajay here is one i know and use...http://www.kmitl.ac.th/~kswichit%20/Pgm89v31_web/Pgm89v31.htmlRC2 and RD2 doesn't need a special programmer i guess.. they have ISP feature. http://www.8051projects.net/forum-t6067.html 2009-01-07T21:33:32-08:00 Ajay well you must consult your programmer manufacturer then... only he can provide you the software, because most of the time programmer softwares are custom designed. That means according to the hardware being used. You must mail or call the vendor/manufacturer of your programmer. http://www.8051projects.net/forum-t6067.html 2009-01-07T21:33:32-08:00 diyora Hi Ajay,I check PGM89 Flash programmer which you suggest me.But it is not support my programmer circuit..Here i attach my programmer cicuit..I have serial port for communication in this circuit... programmer.rar http://www.8051projects.net/forum-t6067.html 2009-01-07T21:33:32-08:00 Ajay I just checked your hardare, its ISP programmer circuit. I have no idea which software will support those connections. and it use parallel port only not serial/COM port.My suggestion is follow what atmel says...if you want you can use this circuit:and you can make use of this software to program you 89S series ICs.http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2877 http://www.8051projects.net/forum-t6067.html 2009-01-07T21:33:32-08:00 sashijoseph The programmer is the same as this one : http://www.kmitl.ac.th/~kswichit%20/IspPgm30a/ISP-Pgm30a.htmlexcept pin 9 of parallel port is used instead of pin8.So make that change and use the ISP-Pgm software.
