I2C protocol uses addressing therefore multiple slaves can be controlled from a single master. When we use 7-bit address, 128 unique addresses are available for the communication. To connect multiple slaves to a single master, follow the below diagram, connect pull-up resistors with the SDA and...
hello, Can anyone tell me how I2Cdetect command works, will it scan any devices which are connected to i2c bus and will it scan and show up the address of devices which are connected to i2c lines coming from MIPI CSI connector?joan Posts: 16294 Joined: Thu Jul 05, 2012 5:09 pm ...

1-Wire Protocol One wire is similar to I2c protocol. But, the difference is one wire protocol uses single data line and ground. It requires no clock signal and the slaves are clocked using internal crystal oscillator. It provides half duplex communication. One wire uses 64-bit addressing schem...
The I2C protocol has established that this start condition is met when the master pulls the SDA line low while the SCL remains high, which notifies the slaves that a transmission is about to start. The master then sends out an address frame, which is shown below. Figure 2: Showing a ...
