I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious ...

We used the Bus Pirate universal serial interface tool to work with the DAC, but the same basic principals apply ... but it would also work fine at 3.3volts. The I2C bus requires pull-up resistors ...
