下面的程序是从“文件”菜单中的“示例程序”中自动生成的“Blink without Delay”。 修改其中的: const long interval=1000 可以修改闪烁LED的频率。单位: ms。 下面是完整的程序。 /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin,...

Surprised at the quality of the sample code - what's provided on Intel's site does not work. I have included the fix below in bold (works with libmraa version 0.5.4+ in IDE) int main(int argc, char **argv) { mraa_platform_t platform = mraa_get...
A few seconds after the upload finishes, you should see the on-board LED start to blink. If it does, congratulations! You've gotten your Arduino Yún up-and-running. If you have problems, please see the troubleshooting suggestions.
