WebI2C slave events ¶. The bus driver sends an event to the backend using the following function: ret = i2c_slave_event (client, event, &val) ‘client’ describes the I2C slave device. ‘event’ is one of the special event types described hereafter. ‘val’ holds an u8 value for the data byte to be read/written and is thus bidirectional.
