嵌入式制作智能定时设备。
最简单的嵌入式开发即利用机智云的SOC方案，利用安信可的编译器进行bin固件的编写。最后在烧写进esp8266中，实现最简单的智能远程控制设备，这次的另一个重要亮点在于实现的硬件计时，也就是实现了硬件端的定时触发，这次的效果是定时启动设备。
依旧是最经典的Makefile修改为esp编译模式
BOOT?=new
APP?=1
SPI_SPEED?=40
SPI_MODE?=QIO
SPI_SIZE_MAP?=6user_main.c的文件简单修改即可，加入要控制的按键初始化。

singleKey[0] = keyInitOne(KEY_0_IO_NUM, KEY_0_IO_MUX, KEY_0_IO_FUNC,
key1LongPress, key1ShortPress);
singleKey[1] = keyInitOne(KEY_1_IO_NUM, KEY_1_IO_MUX, KEY_1_IO_FUNC,
key2LongPress, key2ShortPress);
keys.singleKey = singleKey;
keyParaInit(&keys);
PIN_FUNC_SELECT(PERIPHS_IO_MUX_MTDI_U, FUNC_GPIO12); //GPIO12初始化
GPIO_OUTPUT_SET(GPIO_ID_PIN(12), 1);//GPIO12 低电平输出
