Data transfer may be initiated only when the bus is not busy. The original model became far more popular than anticipated, selling outside its target market for uses such as robotics. Not only is the Raspberry Pi 4 bursting with new hardware features but under the hood there are some extra GPIO functions to make life a bit easier, allowing users to expand their peripherals to their projects without requiring additional hardware 🙂 In particular there are a bunch of extra I2C, UART and SPI interfaces that can be used on the Raspberry Pi 4. As for I2C extensions, one I've wished for would be the ability for slave devices to engage in arbitration in something like the same way masters do (a slave which tries to output a "1" while another slave is outputting a "0" should signals a lost arbitration and drops out for the remainder of that byte) [the high-level protocol would decide at. Use our tool to compare and select the right TI I2C general-purpose I/O (GPIO) device for your design. A good example is the PC printer port, an 8-bit bidirectional I/O port mapped to x86 I/O space, derived from the Centronics port which dates back to. > pio lib search pubsubclient.
