The protocol allows you to connect many devices to a … WebbI 2 C compatible devices connect to the bus with open collector or open drain pins which pull the line LOW. When there is no transmission of data the I 2 C the bus lines idle in a HIGH state; the lines are passively pulled high. Transmission occurs by toggling the lines by pulling LOW and releasing HIGH. Bits are clocked on falling clock edges.
