Ok. Yes, as a starting point I was looking for an IC that can be programmed using serial port. (because I dont have an option to use the parallel port in my laptop)
I just searched on how to program 89S51/52 that supports serial programmer...But in most of the schematics I had seen, it requires a pre-programmed ATmega/89 IC to build an ISP interface...
Here my problem is..can I connect this 89S51/52 (not a pre-programmed one) to my PC serial port and program it...(alos, I don't have a preprogrammed ATmega or any other IC)? Any circuit diagram, please...?
