Hi all..I want to ask..How to know the mode when transfering the data from USB Bluetooth dongle to devices such as handphone? whether serial or parallel? tQ
Of course a USB is a serial device as stated by Nigel Goodwin. 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
