WebbThe inter-integrated circuit or I2C Protocol is a way of serial communication between different devices to exchange their data with each other. It is a half-duplex bi-directional two-wire bus system for transmitting and receiving data between masters (M) and slaves (S). These two wires are Serial clock line or SCL and Serial data line or SDA. Webb3 aug. 2024 · Home/Knowledge Base/What do ‘TX’ and ‘RX’ refer to in the Network Charts? Previous Next.
