In protocols (I2c,SPI,CAN) which one is best?
Answer Posted / smarty
Sudheer has given good explaination,just to add on it :-
1)I2C is half duplex as there are only two lines(SCL and
SDA).
2)SPI is Full Duplex as between a Master and a dedicated
slave as selected by slave_select signal; there are 4 lines
(Spi_clk,Spi_datain,Spi_dataout and slave_select).So,at any
given time data can be sent and received by the master on
two seperate lines.
