It's very clear and efficient. But there a little issue with the \"read\" function. When I call it, I receive this error message :\r\n`\r\nnode_modules/wpi-gpio/wpi-gpio.js:26\r\n    var cmd = ['gpio', flag, method, pin, args.join(' ')].join(' ');\r\n                                              ^\r\nwarn: In script error TypeError: Cannot read property 'join' of undefined\r\n`\r\nThe \"args\" parameter is used in the write function but not in the read one.\r\n\r\nThanks in advance"}}
