Toolchain

Arduino

• in arduino hardware folder, mkdir espressif
• cd espressif and git clone https://github.com/espressif/arduino-esp32.git esp32
• Install binary toolchain

cd esp32/tools,  and,  python get.py

• Install python 2.7, and make sure pyserial installed
• run arduino blink sketch to test, pin LED 1 will blink esp32 TX pin

ESP-IDF

Reference

• Espressif IoT Development Framework, esp-idf-template, and template
• Linux setup

Windows Setup Guide

• Download Mwing from here https://dl.espressif.com/dl/esp32_win32_msys2_environment_and_toolchain-20180110.zip
• Unzip to C: should work like c:\msys32\mingw32.exe, and make dir mkdir -p ~/esp
• Git clone ESP-IDF by commands: cd ~/esp and git clone --recursive https://github.com/espressif/esp-idf.git
• Set PATH: create file export_idf_path.sh at folder C:/msys32/etc/profile.d/, add line export IDF_PATH="C:/msys32/home/user-name/esp/esp-idf", notice to replace the user-name
• Copy code hello_world -> cd ~/esp and cp -r $IDF_PATH/examples/get-started/hello_world .
• Config serial port cd ~/esp/hello_world and make menuconfig, for example config port to COM3 in windows -> Serial flasher config > Default serial port
• make flash or make monitor

Linux Setup Guide

Get start

• create esp folder, and install three parts:

1. esp-idf # development framwork
2. xtensa-esp32-elf # toolchain
3. <myapp-or-anyname> #esp-idf-template example ( turn of wifi, and blink led GPIO4, gpio_set_direction(GPIO_NUM_4, GPIO_MODE_OUTPUT);)
4. <.. any other your apps>

• first install all dependencies: sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial

Install toolchain and Clone ESP-IDF

Install toolchain

• In esp folder:

wget https://dl.espressif.com/dl/xtensa-esp32-elf-linux32-1.22.0-59.tar.gz
unzip toolchain: tar -xzf xtensa*.tar.gz

• latest xtensa file is -> https://dl.espressif.com/dl/xtensa-esp32-elf-linux32-1.22.0-61-gab8375a-5.2.0.tar.gz

Install ESP-IDF

• In esp folder: git clone --recursive https://github.com/espressif/esp-idf.git
• init submodules, in esp-idf folder -> git submodule update --init

Set PATH for linux

Set xtensa PATH

• Option 1-directly add PATH to enviornment: export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
• more details see on http://www.electrodragon.com/w/Category:Linux#PATH
• Verify by command: printenv PATH, it should print

/home/user-name/bin:/home/user-name/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/user-name/esp/xtensa-esp32-elf/bin

Set IDF PATH

• Run a export command for esp-idf and run menu:

export IDF_PATH=~/esp/esp-idf

• and check if it can work by: printenv IDF_PATH

Set both when boot

• nano ~/.bashrc, add two lines at bottom

export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin
export IDF_PATH=~/esp/esp-idf

Start project

• clone example template: in esp folder git clone into myapp folder: git clone https://github.com/espressif/esp-idf-template.git myapp
• or copy:

cd ~/esp
cp -r $IDF_PATH/examples/get-started/hello_world .

• project folder, config it: make menuconfig
• make and flash with download tool: make flash

Other Interpreter

• Luanode
• Micropython
