在Ubuntu下搭建ESP32開發環境
文章目錄
在 CSDN 上面查找ESP8266 系列的博文已經非常多了，但是查找ESP32的文章還是有點缺少，ESP32已經出來很長時間了，使用方法和ES8266非常類似，開發也非常簡單。下面就對ESP32的做一些總結。
本篇文章先描述一下開發環境搭建過程。
說明
- 本片文章中的部分圖片引用自安信可官方Wiki。
- 樂鑫官方也提供了ESP32的SDK的編程指南，參見ESP-IDF編程指南。
開發環境
該開發環境搭建是在 Ubuntu-14.04 (64-bit) 完成的。
硬件準備
ESP32（NodeMCU-32S）
嵌入式平臺使用的是安信可科技提供的NodeMCU-32S。

搭建步驟
在Ubuntu-14.04 上搭建ESP32開發環境的步驟可以分爲以下六步：
- 安裝編譯依賴工具
- 下載並安裝交叉編譯工具鏈
- 配置環境變量
- 下載ESP-IDF源碼
- 配置工程-開始編譯
- 燒寫測試
安裝編譯依賴工具
ESP32 的編譯開發主要依賴兩大核心工具，一個是樂鑫官方提供的ESP32交叉編譯工具鏈，另外一個是python2.7,注意是python2.7。
ESP32 交叉編譯工具鏈能夠正常運行，依賴於 make gcc libncurses5-dev flex bison gperf 等工具，此外還需要使用git 下載源碼，使用python-serial 進行燒寫。
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git make gcc libncurses5-dev flex bison gperf python-serial
下載並安裝交叉編譯工具鏈
在下載交叉編譯工具鏈之前，首先創建一下ESP32專用的開發目錄。
sudo mkdir /esp32
cd /esp32
mkdir crossTools demos sources
然後進入 crossTools 目錄，下載官方交叉編譯工具鏈。
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
配置環境變量
export PATH=$PATH:/esp32/crossTools/xtensa-esp32-elf/bin
環境變量配置完成後，需要檢查一下系統是否能找到交叉編譯工具鏈所在的路徑。
xtensa-esp32-elf-gcc -v
如果能夠看到版本信息，那說明已經正確安裝了。

下載ESP-IDF源碼
ESP32的SDK由樂鑫官方提供，官方命名爲ESP-IDF，該SDK可以從樂鑫官方網站下載，也可以通過github下載。
將ESP-IDF 下載到 sources 目錄下。
cd /esp32/sources
git clone --recursive https://github.com/espressif/esp-idf.git
源碼目錄說明
ESP-IDF的目錄結構如下所示。
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
主要目錄說明
components:ESP-IDF的核心組件
examples:ESP-IDF提供的實例程序
make:ESP-IDF工程管理目錄
tools:ESP-IDF提供的工具集
docs:ESP-IDF相關文檔
這裏，筆者着重說明一下 examples目錄，其目錄結構如下所示。
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 8 root root 4.0K 12月 4 12:46 ..
drwxr-xr-x 26 root root 4.0K 12月 4 12:46 bluetooth
drwxr-xr-x 3 root root 4.0K 12月 4 12:46 build_system
drwxr-xr-x 4 root root 4.0K 12月 4 12:46 ethernet
drwxr-xr-x 4 root root 4.0K 12月 4 12:46 get-started

drwxr-xr-x 26 root root 4.0K 12月 4 12:46 peripherals

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
從這裏面可以看出來，ESP-IDF 已經爲開發者提供了多種SDK實例，在編譯環境搭建完成之後，這些實例就可以直接編譯然後下載到ESP32上面看效果了。可以看到樂鑫官方已經爲每一個目錄下面編寫了markdown文件，對這些工程文件進行詳細的說明，因此注意查看每一個目錄下的 markdown 文件非常重要。
其中，最簡單的實例在 gat-started 目錄下。
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 .
drwxr-xr-x 13 root root 4.0K 12月 4 12:46 ..
drwxr-xr-x 3 root root 4.0K 12月 4 12:46 blink
drwxr-xr-x 3 root root 4.0K 12月 4 12:46 hello_world
-rw-r--r-- 1 root root 197 12月 4 12:46 README.md
配置工程-開始編譯
下面就從一個最簡單的 hello_world 工程開始進行編譯。
將 /esp32/sources/esp-idf/examples/get-started/ 目錄下的 hello_world 實例拷貝到 /esp32/demos/ 下。
root@qiao-virtual-machine:/esp32/sources/esp-idf/examples/get-started# cp -fr hello_world /esp32/demos/
配置 IDF_PATH 環境變量。該環境變量是用來指向 ESP-IDF 的實際路徑的，用於make編譯使用。
export IDF_PATH=/esp32/sources/esp-idf
進入 /esp32/demos/hello_world 目錄，開始配置工程。
cd /esp32/demos/hello_world/
make menuconfig
使用 make menuconfig 命令可以進入到工程配置頁面，如下。
進入 SDK tool configuration 中，配置 python版本爲python2
進入 Bootloader config 中，配置bootloader的打印日誌顯示信息等級爲warning
進入 Secure boot configuration，開發階段建議關閉secure boot功能
進入 Serial flasher config，指定用於燒寫程序的串口設備，一般使用USB轉串口的選擇/dev/ttyUSB0即可，設置默認的波特率爲115200，Flash的SPI模式爲DIO，SPI速率爲40MHz，Flash的大小爲2MB
進入 Partition Table設置分區表，爲了更好的管理SPI Flash，ESP-IDF引入了分區表的概念，默認使用Single factory app,no OTA製作分區BIN
進入 Component config ，該配置選項是對ESP-IDF的內核進行的更加詳細的配置
配置完成後，保存並退出，將會在工程根目錄下新生成一個build文件夾和sdkconfig文件。
在工程根目錄下輸入make all將會編譯所有的BIN文件，默認會編譯bootloader、partition_table、app文件,並且還會提示如何進行燒寫。下面貼出來一個基本配置工程的完整編譯日誌,僅供參考。
筆者的的編譯日誌之所以這麼多，是因爲在 配置工程 時 Component config 採用了默認配置。

LD build/hello-world.elf
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
編譯完成後，就會在 /esp32/demos/hello_world/build 目錄下生成 partitions_singleapp.bin 燒寫文件，下面就可以將該燒寫文件燒錄到ESP32中了。
燒寫測試
將 NodeMCU-32S接入到電腦上。如果在 /dev/ 目錄識別到 ttyUSB0 則代表已經識別出 NodeMCU-32S的串口了。
root@qiao-virtual-machine:/dev# ls ttyUSB*
ttyUSB0
開始燒寫
首先長按Boot鍵，同時按 reset鍵，系統將會進入下載模式，然後 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.

因爲 hello_world 工程中最後會對esp32進行重啓，因此查看的打印日誌也會不斷的看到 ESP32在重啓。

環境搭建過程中遇到的問題記錄
安裝 pip 和 python庫
pip 安裝
由於我搭建的 ESP32 開發環境是在新裝的ubuntu上面搭建的，系統中缺少一些 python 必備的庫，需要使用 pip 安裝。因此需要在ubuntu上安裝python-2.7 的 pip。
安裝方法
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
sudo python get-pip.py
python 庫依賴
# This is a list of python packages needed for ESP-IDF. This file is used with pip.
# Please see the Get Started section of the ESP-IDF Programming Guide for further information.

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.
