ESP8266 物联网开发 -- 3，GPIO控制流水灯
直接上GPIO控制流水灯的代码， GPIO 12 13 14 配置成output，控制3个灯， 用RTOS任务中进行延时100tick进行流水

* FunctionName : user_rf_cal_sector_set
* Description : SDK just reversed 4 sectors, used for rf init data and paramters.
* We add this function to force users to set rf cal sector, since
* we don't know which sector is free in user's application.
* sector map for last several sectors : ABCCC
* A : rf cal
* B : rf init data
* C : sdk parameters
* Parameters : none
* Returns : rf cal sector

按照之前文章配置的下载文件，遇到程序下载运行跑飞的问题。后来把几个数据段的文件也下载后正常，原因不清楚还。下载配置见下图 Non-FOTA
