All versions of Linux are supported, as long as I 2 C support is included in the kernel. By default, i2cset will wait for a confirmation from the user before messing with the I2C bus. So, the first line writes the value 0x01 (switch ON) to the address 0x00 (green lights) on the device with address 0x15 (our I2C light controller) and the second line sets 0x00 (switch OFF) to the address 0x01 (red light) on the device with address 0x15. The ./build is a script to build Wiring Pi from the source files. possible mode is c, which doesn't write any value (so-called short respectively. i2cbus indicates the number or name of the I2C bus to be scanned, and should correspond to one of the busses listed by i2cdetect -l.The optional parameters first and last restrict the scanning range (default: from 0x03 to 0x77). Options-V. By default, i2cset will refuse to access a device which is already under the control of a kernel driver. language:bash ./build At this point, the library should work. Using this IC, you can use only the SDA and SCL pins of your Arduino board to control up to 8 digital I/O ports. # i2cset -y 9 0x50 0x00 ; i2cget -y 9 0x50 ; i2cget -y 9 0x50.
