-This is a simple project template.
-
-sample_lib is an example for multi-level folder Makefile, notice the folder structure and each Makefile, you can get the clue.
-
-
-HOWTO:
-1. Copy this folder to anywhere.
-Example:
-   Copy to ~/workspace/project_template
-   You can rename this folder as you like.
-
-2. Export SDK_PATH and BIN_PATH.
-Example:
-   Your SDK path is ~/esp_iot_rtos_sdk, and want generate bin at ~/esp8266_bin.
-   Do follow steps:
-     1>. export SDK_PATH=~/esp_iot_rtos_sdk
-     2>. export BIN_PATH=~/esp8266_bin
-   SDK and project are seperate, you can update SDK without change your project.
-
-3. Enter project_template folder, run ./gen_misc.sh, and follow the tips and steps.
-
-
-Compile Options:
-(1) COMPILE
-    Possible value: xcc
-    Default value:
-    If not set, use gcc by default.
-
-(2) BOOT
-    Possible value: none/old/new
-      none: no need boot
-      old: use boot_v1.1
-      new: use boot_v1.2
-    Default value: new
-
-(3) APP
-    Possible value: 0/1/2
-      0: original mode, generate eagle.app.v6.flash.bin and eagle.app.v6.irom0text.bin
-      1: generate user1
-      2: generate user2
-    Default value: 0
-
-(3) SPI_SPEED
-    Possible value: 20/26.7/40/80
-    Default value: 40
-
-(4) SPI_MODE
-    Possible value: QIO/QOUT/DIO/DOUT
-    Default value: QIO
-
-(4) SPI_SIZE_MAP
-    Possible value: 0/2/3/4/5/6
-    Default value: 0
-
-For example:
-    make COMPILE=gcc BOOT=new APP=1 SPI_SPEED=40 SPI_MODE=QIO SPI_SIZE_MAP=0
