Analog Devices Blackfin Processor SCCB Software Interface for Configuring I2C Slave Devices
This Engineer-to-Engineer Note (EE-204) details how to implement the Serial Camera Control Bus (SCCB) interface using software and general-purpose pins on Blackfin processors. It provides a solution for Blackfin derivatives that lack a built-in two-wire interface (TWI) for configuring video devices, allowing the processor to act as an I2C master.
