WebThe I2C bus is a standard bidirectional interface that uses a controller, known as the master, to communicate with slave devices. A slave may not transmit data unless it has been addressed by the master. Each device on the I2C bus has a specific device address to differentiate between other devices that are on the same I2C bus. Many slave ... WebThis will probably confuse all other clients on your bus, so don’t try this. This is often used to gather transmits from multiple data buffers in system memory into something that appears as a single transfer to the I2C device but may also be used between direction changes by some rare devices.

WebOverview. The I2C-MS core is a controller for the Inter-Integrated Circuit (I2C) bus. The highly configurable core can implement an I2C bus master, slave, or a combined master and slave, and it communicates with the host via an APB, AHB, or Wishbone slave interface. The core supports all variations and configurations of I2C networks.
