Dear All,
I am still learner in this area, first of all i need to prepare a low cost Serial ISP programmer for 89S52 microcontroller & It's burner software as well.
I've google lots of time & found ISP programmers using DB25 (LPT port) but I didn't find any ISP programmer using DB9.
I'll be very thankfull if any body suggest me circuit idea or any link...!!
