Oh no! 1 Indicates the number or name of the I2C bus to be scanned. TP. Npcap (with Wireshark maybe) should be installed before in Winpcap compatible mode. WiringPi includes a library which can make it easier to use the Raspberry Pi’s on-board I2C interface.. Not all systems have the I2C development libraries and headers installed, and when you build wiringPi, it detects this at build time.If you are using these helper functions and you get link errors, it means that wiringPi is not installed with the I2C helper functions. i2cset.c - A user-space program to write an I2C register. mcp23017 and i2cset example .
