Using the older system by unticking the "Deep Library search" menu item and then adding #includes for the required libs (to the project_name.ino) will compile in less than 1 second. The following applies to versions of Visual Micro older than 1607.7 ...
The Arduino uses the maximum startup delay of 14CK + 65ms (CKSEL0=1, SUT1=1, SUT0=1) which are also the default settings for new ATmega 328/328P chips. CHDIV8 (Clock Divide) ATmega 328/328P chips have a built in RC oscillator which has a 8.0MHz frequency. New chips are shippe...

delay(ms) 参数: ms: 暂停的毫秒数。允许的数据类型:unsigned long 将程序延迟1000ms(1s)。 演示效果和串行输出结果: LED模块将1秒亮,1秒灭。 LED模块亮度调整:LED模块上有可变电阻,可以用螺丝刀拧动它,使灯光更亮。 拆分指南 如果模块从主板上被分离,则需要使用Grove数据线来连接 Grove LED 和Seeeduino Lotu...
