在 CSDN 上面查找ESP8266 系列的博文已经非常多了，但是查找ESP32的文章还是有点缺少，ESP32已经出来很长时间了，使用方法和ES8266非常类似，开发也非常简单。下面就对ESP32的做一些总结。
本篇文章先描述一下开发环境搭建过程。
说明
- 本片文章中的部分图片引用自安信可官方Wiki。
- 乐鑫官方也提供了ESP32的SDK的编程指南，参见ESP-IDF编程指南。
开发环境
该开发环境搭建是在 Ubuntu-14.04 (64-bit) 完成的。
硬件准备
ESP32（NodeMCU-32S）
嵌入式平台使用的是安信可科技提供的NodeMCU-32S。
NodeMCU-32S 引脚图
搭建步骤
在Ubuntu-14.04 上搭建ESP32开发环境的步骤可以分为以下六步：
- 安装编译依赖工具
- 下载并安装交叉编译工具链
- 配置环境变量
- 下载ESP-IDF源码
- 配置工程-开始编译
- 烧写测试
安装编译依赖工具
ESP32 的编译开发主要依赖两大核心工具，一个是乐鑫官方提供的ESP32交叉编译工具链，另外一个是python2.7,注意是python2.7。
ESP32 交叉编译工具链能够正常运行，依赖于 make gcc libncurses5-dev flex bison gperf 等工具，此外还需要使用git 下载源码，使用python-serial 进行烧写。
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git make gcc libncurses5-dev flex bison gperf python-serial
下载并安装交叉编译工具链
在下载交叉编译工具链之前，首先创建一下ESP32专用的开发目录。
sudo mkdir /esp32
cd /esp32
mkdir crossTools demos sources
然后进入 crossTools 目录，下载官方交叉编译工具链。
cd crossTools
wget https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz
tar xzvf xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz
配置环境变量
export PATH=$PATH:/esp32/crossTools/xtensa-esp32-elf/bin
环境变量配置完成后，需要检查一下系统是否能找到交叉编译工具链所在的路径。
xtensa-esp32-elf-gcc -v
如果能够看到版本信息，那说明已经正确安装了。

下载ESP-IDF源码
ESP32的SDK由乐鑫官方提供，官方命名为ESP-IDF，该SDK可以从乐鑫官方网站下载，也可以通过github下载。
将ESP-IDF 下载到 sources 目录下。
cd /esp32/sources
git clone --recursive https://github.com/espressif/esp-idf.git
源码目录说明
ESP-IDF的目录结构如下所示。
root@qiao-virtual-machine:/esp32/sources/esp-idf# ls
add_path.sh CMakeLists.txt components CONTRIBUTING.rst docs examples Kconfig LICENSE make README.md requirements.txt tools
主要目录说明
components:ESP-IDF的核心组件
examples:ESP-IDF提供的实例程序
make:ESP-IDF工程管理目录
tools:ESP-IDF提供的工具集
docs:ESP-IDF相关文档
这里，笔者着重说明一下 examples目录，其目录结构如下所示。
root@qiao-virtual-machine:/esp32/sources/esp-idf/examples# ls -alh
total 56K
drwxr-xr-x 13 root root 4.0K 12月 4 12:46 .

drwxr-xr-x 19 root root 4.0K 12月 4 12:46 system
drwxr-xr-x 11 root root 4.0K 12月 4 12:46 wifi
从这里面可以看出来，ESP-IDF 已经为开发者提供了多种SDK实例，在编译环境搭建完成之后，这些实例就可以直接编译然后下载到ESP32上面看效果了。可以看到乐鑫官方已经为每一个目录下面编写了markdown文件，对这些工程文件进行详细的说明，因此注意查看每一个目录下的 markdown 文件非常重要。
其中，最简单的实例在 gat-started 目录下。
root@qiao-virtual-machine:/esp32/sources/esp-idf/examples/get-started# ls -alh
total 20K
drwxr-xr-x 4 root root 4.0K 12月 4 12:46 .

-rw-r--r-- 1 root root 197 12月 4 12:46 README.md
配置工程-开始编译
下面就从一个最简单的 hello_world 工程开始进行编译。
将 /esp32/sources/esp-idf/examples/get-started/ 目录下的 hello_world 实例拷贝到 /esp32/demos/ 下。
root@qiao-virtual-machine:/esp32/sources/esp-idf/examples/get-started# cp -fr hello_world /esp32/demos/
配置 IDF_PATH 环境变量。该环境变量是用来指向 ESP-IDF 的实际路径的，用于make编译使用。
export IDF_PATH=/esp32/sources/esp-idf
进入 /esp32/demos/hello_world 目录，开始配置工程。
cd /esp32/demos/hello_world/
make menuconfig
使用 make menuconfig 命令可以进入到工程配置页面，如下。
进入 SDK tool configuration 中，配置 python版本为python2
进入 Bootloader config 中，配置bootloader的打印日志显示信息等级为warning
进入 Secure boot configuration，开发阶段建议关闭secure boot功能
进入 Serial flasher config，指定用于烧写程序的串口设备，一般使用USB转串口的选择/dev/ttyUSB0即可，设置默认的波特率为115200，Flash的SPI模式为DIO，SPI速率为40MHz，Flash的大小为2MB
进入 Partition Table设置分区表，为了更好的管理SPI Flash，ESP-IDF引入了分区表的概念，默认使用Single factory app,no OTA制作分区BIN
进入 Component config ，该配置选项是对ESP-IDF的内核进行的更加详细的配置
配置完成后，保存并退出，将会在工程根目录下新生成一个build文件夹和sdkconfig文件。
在工程根目录下输入make all将会编译所有的BIN文件，默认会编译bootloader、partition_table、app文件,并且还会提示如何进行烧写。下面贴出来一个基本配置工程的完整编译日志,仅供参考。
笔者的的编译日志之所以这么多，是因为在 配置工程 时 Component config 采用了默认配置。
root@qiao-virtual-machine:/esp32/demos/hello_world# make all

esptool.py v2.6-beta1
To flash all build output, run 'make flash' or:
python /esp32/sources/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 40m --flash_size detect 0x1000 /esp32/demos/hello_world/build/bootloader/bootloader.bin 0x10000 /esp32/demos/hello_world/build/hello-world.bin 0x8000 /esp32/demos/hello_world/build/partitions_singleapp.bin
编译完成后，就会在 /esp32/demos/hello_world/build 目录下生成 partitions_singleapp.bin 烧写文件，下面就可以将该烧写文件烧录到ESP32中了。
烧写测试
将 NodeMCU-32S接入到电脑上。如果在 /dev/ 目录识别到 ttyUSB0 则代表已经识别出 NodeMCU-32S的串口了。
root@qiao-virtual-machine:/dev# ls ttyUSB*
ttyUSB0
开始烧写
首先长按Boot键，同时按 reset键，系统将会进入下载模式，然后 make flash.
root@qiao-virtual-machine:/esp32/demos/hello_world# make flash
Toolchain path: /esp32/crosstools/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc
Toolchain version: crosstool-ng-1.22.0-80-g6c4433a
Compiler version: 5.2.0
Python requirements from /esp32/sources/esp-idf/requirements.txt are satisfied.

因为 hello_world 工程中最后会对esp32进行重启，因此查看的打印日志也会不断的看到 ESP32在重启。

环境搭建过程中遇到的问题记录
安装 pip 和 python库
pip 安装
由于我搭建的 ESP32 开发环境是在新装的ubuntu上面搭建的，系统中缺少一些 python 必备的库，需要使用 pip 安装。因此需要在ubuntu上安装python-2.7 的 pip。
安装方法
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
sudo python get-pip.py
python 库依赖
# This is a list of python packages needed for ESP-IDF. This file is used with pip.

setuptools
# The setuptools package is required to install source distributions and on some systems is not installed by default.
# Please keep it as the first item of this list.

ESP32 的开发环境搭建完成了，下面就就开始正式的ESP32开发了。同样的，笔记教程会不断更新中…
