Contribute to Ankita0 tivac_samples development by creating an account on GitHub. com Jul 30 2014 Preface . Jul 22 2018 This experiment connects three Tiva C boards together to form an I2C bus. Program In the example presented below a key pressed on the keyboard is displayed on an LCD. In which one wire is used for the data SDA and other wire is used for the clock SCL . Also unlike SPI I 2 C can support a multi master system allowing more than one master to communicate with all devices on the bus although the master devices can 39 t talk to each other over the bus and must take turns using the bus lines . The blocking communication means that the MCU stalls until the byte is transferred from the data register. It illustrates all of the I 2 C features described before clock stretching arbitration start stop bit ack nack . Mar 20 2018 The I2C component supports I2C slave master and multi master configurations. This shouldn t block the cpu and therefore shouldn t intervene with grbl s stepper signal generation. c driver is for a Microchip 24XX1025 I2C Serial EEPROM with 1024K bits of memory and the ds1631.
