Hi Newbie86,
if your dongle has at least 10 pins it's parallel, if they are less it must be serial.
Hi Boncuk..about 10 pins?Which part must to be considered?My dongle is just seem like this Usb Dongle .. Can anyone or boncuk mention it?
A parallel device must have eight data lines. Considering supply voltage makes a total of ten pins minimum.
Well, you can have 2 data lines and still have parallel connection
if you are sending more then 1 bit at a time, the connection is parallel, if sending only 1 bit at a time then it is serial. LCD in 4bit mode is still parallel connections even with only 4 data lines
