- Development Status
- Installing options:
- ESP32Dev Board PINMAP
Most of the framework is implemented. Most noticable is the missing analogWrite. While analogWrite is on it's way, there are a few other options that you can use:
- 16 channels LEDC which is PWM
- 8 channels SigmaDelta which uses SigmaDelta modulation
- 2 channels DAC which gives real analog output
-
Install latest Arduino IDE from arduino.cc
-
Open Terminal and execute the following command (copy->paste and hit enter):
curl -o get-pip.py https://bootstrap.pypa.io/get-pip.py && \ sudo python get-pip.py && \ sudo pip install pyserial && \ mkdir -p ~/Documents/Arduino/hardware/espressif && \ cd ~/Documents/Arduino/hardware/espressif && \ git clone https://github.com/espressif/arduino-esp32.git esp32 && \ cd esp32/tools/ && \ python get.py
-
Restart Arduino IDE
-

PlatformIO is an open source ecosystem for IoT development with cross platform build system, library manager and full support for Espressif ESP32 development. It works on the popular host OS: Mac OS X, Windows, Linux 32/64, Linux ARM (like Raspberry Pi, BeagleBone, CubieBoard).
- What is PlatformIO?
- PlatformIO IDE
- Quick Start with PlatformIO IDE or PlatformIO Core
- Integration with Cloud and Standalone IDEs - Cloud9, Codeanywehre, Eclipse Che (Codenvy), Atom, CLion, Eclipse, Emacs, NetBeans, Qt Creator, Sublime Text, VIM and Visual Studio
- Project Examples
-
Download and install esp-idf
-
Create blank idf project (from one of the examples)
-
in the project folder, create a folder called components and clone this repository inside
mkdir -p components && \ cd components && \ git clone https://github.com/espressif/arduino-esp32.git arduino && \ cd .. && \ make menuconfig
-
make menuconfighas some Arduino options- "Autostart Arduino setup and loop on boot"
-
If you enable this options, your main.cpp should be formated like any other sketch
//file: main.cpp #include "Arduino.h" void setup(){ Serial.begin(115200); } void loop(){ Serial.println("loop"); delay(1000); } -
Else you need to implement
app_main()and callinitArduino();in it.Keep in mind that setup() and loop() will not be called in this case
//file: main.cpp #include "Arduino.h" extern "C" void app_main() { initArduino(); pinMode(4, OUTPUT); digitalWrite(4, HIGH); //do your own thing }
-
- "Disable mutex locks for HAL"
- If enabled, there will be no protection on the drivers from concurently accessing them from another thread/interrupt/core
- "Autoconnect WiFi on boot"
- If enabled, WiFi will start with the last known configuration
- Else it will wait for WiFi.begin
- "Autostart Arduino setup and loop on boot"
-
make flash monitorwill build, upload and open serial monitor to your board
