打开工具源码注释掉

#if 0
        if (mode != MODE_READ && !(funcs & I2C_FUNC_SMBUS_QUICK)) {
                fprintf(stderr, "Error: Can't use SMBus Quick Write command "
                        "on this bus\n");
                close(file);
                exit(1);
        }
        if (mode != MODE_QUICK && !(funcs & I2C_FUNC_SMBUS_READ_BYTE)) {
                fprintf(stderr, "Error: Can't use SMBus Read Byte command "
                        "on this bus\n");
                close(file);
                exit(1);
        }
#endif
重新编译即可使用i2c工具
