ESP8266官方两种代码的学习
ESP8266官方提供的两种NonOS_SDK和IOT_RTOS_SDK的编译和简单使用方法。
官方的NonOS_SDK其中的编译环境不需要作任何修改
但是官方为了使RTOS_SDK和NonOS_SDK区别开来，
在RTOS_SDK中做了部分修改加入了SDK_PATH和BIN_PATH两个环境变量，
因此需要做些修改直接使RTOS_SDK的环境变量做些修改；
以下是修改的具体代码：
（1）examples示例代码编译时需要使用gen_misc.sh，该文件的修改具体情况：
diff -r orign_gen_misc.sh new_gen_misc.sh

< ******NOTICE******
< MUST set SDK_PATH & BIN_PATH firstly!!!
< example:
< export SDK_PATH=~/esp_iot_sdk_freertos

< !
<
< export SDK_PATH=
< export BIN_PATH=

< if [ $BIN_PATH ]; then

> if [ -z "$input" ]; then
> boot=none
> elif [ $input == 0 ]; then
> boot=old
> elif [ $input == 1 ]; then
> boot=new

(2)examples示例代码下的Makefile(这里修改的为websocket示例代码下的Makefile)：
diff -r orign_Makefile new_Makefile

< LDDIR = $(SDK_PATH)/ld
---
> LDDIR = ../ld
53c53
< -L$(SDK_PATH)/lib \
---
> -L../lib \
120c120,121
< sinclude $(SDK_PATH)/Makefile
---
> PDIR := ../$(PDIR)
> sinclude $(PDIR)Makefile
(3)源码根目录的Makefile文件修改：
diff -r orig_Makefile new_Makefile
