[SOLVED] 2 wire serial interface

[Vengateswaran]

How transmission of data happens with the help 2-wire serial interface.??

 

[Venkadesh_M]

One line is used for clock and other line is used for data,
A master controls the transmission and reception..
There is only one data line so only one device can transmit at a time,
and the targeted device will give acknowledgement over the data line.....

 

[Vengateswaran]

If so, Hw it can work in a full duplex mode..??

 

[Venkadesh_M]

Yeah, How it can be in full duplex??

I2C is Half duplex communication....

 

[deeplearns]

I2C or 2-wire serial interface cant be full duplex its either Master transmit or master recieve , or slave transmit or slave recieve .
it requires start and stop bit generation to start and end transmit and acknowledge sequence from the master or slave for sucessful recieval of data .

for full duplex mode u can choose SPI that is 4/3-wire communication.
