Hi frnz,
I am trying to program at89s52 using just the TXD RXD pins of MCU and serial to usb converter. I've given it a lot of tries but it doesn't work. Am I doing it right or have i just interfaced it for serial communication. and whts the use of ISP ( sorry i am totally new to this stuff).
Can anyone help me with some schematic for programming the mcu. And is there a need for 2 mcu to program one of it. Whats a preprogrammed mcu ?
Thanks in advance.
