WebWe notice that the gpio numbering is on the form exemplified by GPIO3_A5. GPIOs are organized in four banks, identified as GPIO0 through GPIO3. Then within each, there are several sets of ports associated with one of four pads, and numbered within each of these. Each gpio is identified thus on schematics and on the map referenced above, as Webgpio load i2c If you need a baud rate other than the default 100Kbps, then you can supply this on the command-line: gpio load i2c 1000 will set the baud rate to 1000Kbps – ie. 1,000,000 bps. (K here is times 1000) To use the I2C library, you need to: #include in your program. Programs need to be linked with -lwiringPias usual.
