Arduino IDE expressif installation location info

[rrobinet]

Hi,
I would like to mention that the installation should not always be located under:
~/Documents/Arduino/.... typically ~/Documents/Arduino/hardware/espressif
But under the location defined in the Arduino preferences has
Sketchbook location:
For example in my case defined as:
/Users/Robert/Data/Our Documents/Projets Techniques/Domotic/Arduino/Sketch
The practical location should be:
/Users/Robert/Data/Our Documents/Projets Techniques/Domotic/Arduino/hardware/espressif

Thanks Robert. I'm wondering if my SEVERAL attempts to get my ESP32 setup to work is because of location issues - I'm getting lots of "no such file" or duplicates of things, etc.

UPDATE: I was not using my exact Sketchbook path; I had one path segment missing. I updated the script (below) and now the installation works.

I also found the forum focused on Arduino for ESP32.

Yes, I was a complete noob with ESP32. Just got my first dev board. Thanks Robert for posting this.

@MrJustPaul, did you get your setup to work?

I too have a non-default Sketchbook location. That explains why the Installation Instructions for Mac don't work as-is. As is pointed out in OP, the installation script is hard coded for the Sketchbook location to be ~/Documents/Arduino.

For historical reasons, my Sketchbook location is ~/Developer/Projects/Arduino/Arduino-trunk. So I changed the script to:

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

and executed it. The following was printed to the Terminal screen:

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

As far as I can tell, the installation was successful. However, when I run the Arduino IDE, I don't see anything that indicates that arduino-esp32 is available. For example, under the Tools/Board: menu, I assume that there should be some esp32 targets. Questions follow...

Is there a arduino-esp32 focused forum where I can go to get help? If so, I'll go there.

If not, then...

Was my installation attempt successful? How can I tell?

I'm using macOS 10.12.6. Tested with Arduino IDE versions 1.8.1, 1.8.2, and 1.8.4.

Hi,
All I can say is that was the trick for me:
Most of my alien (no-Arduino products) libraries are under my sketchbook location /hardware.
Please verify if this i actually the case:
My Sketchbook location is:
/Users/Robert/Data/Our Documents/Projets Techniques/Domotic/Arduino/Sketch
and the espressif set is under:
/Users/Robert/Data/Our Documents/Projets Techniques/Domotic/Arduino/Sketch/Hardware/espressif/esp32

You have to restart Arduino to actually see it under the Tools menu.
