## Development Status
|
||||
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](https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-ledc.h) which is PWM
|
||||
- 8 channels [SigmaDelta](https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-sigmadelta.h) which uses SigmaDelta modulation
|
||||
- 2 channels [DAC](https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-dac.h) which gives real analog output
|
||||
- 16 channels [LEDC](cores/esp32/esp32-hal-ledc.h) which is PWM
|
||||
- 8 channels [SigmaDelta](cores/esp32/esp32-hal-sigmadelta.h) which uses SigmaDelta modulation
|
||||
- 2 channels [DAC](cores/esp32/esp32-hal-dac.h) which gives real analog output
|

## Installation Instructions
|
||||
|
||||
### Using through Arduino IDE
|
||||
|
||||
#### [Instructions for Windows](doc/windows.md)
|
||||
|
||||
#### Instructions for Mac
|
||||
- Install latest Arduino IDE from [arduino.cc](https://www.arduino.cc/en/Main/Software)
|
||||
- Open Terminal and execute the following command (copy->paste and hit enter):
|
||||
|
||||
```bash
|
||||
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
|
||||
|
||||
#### Instructions for Debian/Ubuntu Linux
|
||||
- Install latest Arduino IDE from [arduino.cc](https://www.arduino.cc/en/Main/Software)
|
||||
- Open Terminal and execute the following command (copy->paste and hit enter):
|
||||
|
||||
```bash
|
||||
sudo usermod -a -G dialout $USER && \
|
||||
sudo apt-get install git && \
|
||||
wget https://bootstrap.pypa.io/get-pip.py && \
|
||||
sudo python get-pip.py && \
|
||||

|
||||
- Restart Arduino IDE
|
||||
|
||||
#### Instructions for Fedora
|
||||
- Install the latest Arduino IDE from [arduino.cc](https://www.arduino.cc/en/Main/Software). `$ sudo dnf -y install arduino` will most likely install an older release.
|
||||
- Open Terminal and execute the following command (copy->paste and hit enter):
|
||||
|
||||
```bash
|
||||
sudo usermod -a -G dialout $USER && \

|
||||
mkdir -p ~/Arduino/hardware/espressif && \
|
||||
cd ~/Arduino/hardware/espressif && \
|
||||
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
|
||||
cd esp32/tools/ && \
|
||||
python get.py
|
||||
```
|
||||

#### Decoding exceptions
|
||||
|
||||
You can use [EspExceptionDecoder](https://github.com/me-no-dev/EspExceptionDecoder) to get meaningful call trace.
|
||||
|
||||
### Using PlatformIO
|
||||
#### Issue/Bug report template
|
||||
Before reporting an issue, make sure you've searched for similar one that was already created. Also make sure to go through all the issues labelled as [for reference](https://github.com/espressif/arduino-esp32/issues?utf8=%E2%9C%93&q=is%3Aissue%20label%3A%22for%20reference%22%20).
|
||||
|
||||
[PlatformIO](http://platformio.org) 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).
|
||||
Finally, if you're sure no one else had the issue, follow the [ISSUE_TEMPLATE](docs/ISSUE_TEMPLATE.md) while reporting any issue.
|
||||
|
||||
- [What is PlatformIO?](http://docs.platformio.org/page/what-is-platformio.html)
|
||||
- [PlatformIO IDE](http://platformio.org/platformio-ide)
|
||||
- Quick Start with [PlatformIO IDE](http://docs.platformio.org/page/ide/atom.html#quick-start) or [PlatformIO Core](http://docs.platformio.org/page/core.html)
|
||||
- [Integration with Cloud and Standalone IDEs](http://docs.platformio.org/page/ide.html) -

- [Using "Stage" (Git) version of Arduino Core](http://docs.platformio.org/page/platforms/espressif32.html#using-arduino-framework-with-staging-version)
|
||||
|
||||
### Building with make
|
||||
|
||||
[makeEspArduino](https://github.com/plerup/makeEspArduino) is a generic makefile for any ESP8266/ESP32 Arduino project.
|
||||
Using make instead of the Arduino IDE makes it easier to do automated and production builds.
|
||||
|
||||
### Using as ESP-IDF component
|
||||
- Download and install [esp-idf](https://github.com/espressif/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
|
||||
|
||||
```bash
|
||||
mkdir -p components && \
|
||||
cd components && \
|
||||
git clone https://github.com/espressif/arduino-esp32.git arduino && \
|
||||
cd .. && \
|
||||
make menuconfig
|
||||
```
|
||||
- ```make menuconfig``` has 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
|
||||
|
||||
```arduino
|
||||
//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 call ```initArduino();``` in it.
|
||||
|
||||
Keep in mind that setup() and loop() will not be called in this case.
|
||||
If you plan to base your code on examples provided in [esp-idf](https://github.com/espressif/esp-idf/tree/master/examples), please make sure move the app_main() function in main.cpp from the files in the example.
|
||||
|
||||
```arduino
|
||||
//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
|
||||
- ```make flash monitor``` will build, upload and open serial monitor to your board
|
||||
|
||||
## ESP32Dev Board PINMAP
|
||||
|
||||
|
||||
|
||||
|
||||
## Hint
|
||||
|
||||
Sometimes to program ESP32 via serial you must keep GPIO0 LOW during the programming process
