Equipped with debugging power, Pugs dwelled further into stuff of more involved programming – the protocols – specifically the I 2 C protocol. Other great examples can be found on Github, like this I2CBus library. The i2c. A slave may not transmit data unless it has been addressed by the master. Each registered I2C adapter gets a number, counting from 0. If no device is pulling on the line, it will “float high”.
The I2C bus specification specifies that in standard-mode I2C, the slave address is 7-bits long followed by the read/write bit. 1,382. For non-mux cases an I2C client * is attached per netdev. . After that Displaying the data received from EEPROM.
