Hi friends,
I am doing a project on AT89s52 and want to build a isp using serial port.
As we know we can build a ISP using parallel port and MOSI,MISO,SCK lines.
Can anyone tell me whether i can build a isp using serial port, MAX 232 and RX-TX pins of AT89s52.
Attaching a schematic png.
If this schematic does not work then please tell me if by keeping momentory switch and ISP switch(for programming and run mode) in the schematic can i go for parallel port as shown in the second schematic(where switches are not shown).
Schematic of autoisp is welcome.
