Arduino submodule failed. I downloaded the latest, like this (and working):

rm -r components/arduino/
git clone https://github.com/espressif/arduino-esp32.git components/arduino-esp32
cd components/arduino-esp32 && git submodule update --init --recursive && cd ../..

Nice if this could be fixed in the code, wtakuo :)

Hi wtakuo,

thanks for your work on this…. Nice that M5Stack included your work.

Your efforts inspired me to give installation another crack – this time using Linux instead of Windows. MUCH better so far.

Just have to determine which serial port is in use… got a long list rather than a defined port when following the ESP-IDF setup guide that outlined how to distinguish the serial port in use. Will follow it up laterz.

In addition, to tidy up the repository of my fixed M5Stack-IDF, I moved my modifications to components_patch branch. So main branch no longer contains the fix now. If you'd like to try my fixed version of M5Stack-IDF, please do like the following commands.

git clone --recursive -b components_patch https://github.com/wtakuo/M5Stack-IDF.git

Sorry for inconvenience due to the changes.

The path variables in component.mk should look like the following.

COMPONENT_SRCDIRS := src src/utility src/Fonts
COMPONENT_ADD_INCLUDEDIRS := src

As shown in the above code, I added src/Fonts to COMPONENT_SRCDIRS and removed unnecessary "." (current directory) from both paths. Header files in the subdirectories are specified using relative paths from src. So we don't need to add these subdirectories to COMPONENT_ADD_INCLUDEDIRS.

Anyway, I sent pull request regarding this fix. If my PR is accepted, the patch file in https://github.com/wtakuo/M5Stack-IDF will be unnecessary.

Unfortunately, current https://github.com/m5stack/M5Stack-IDF looks outdated and incomplete. So I use https://github.com/m5stack/M5Stack as an IDF component as well as https://github.com/espressif/arduino-esp32 .

The project directory looks like the following.

Makefile
sdkconfig
components/
    arduino/            (recursive clone of https://github.com/espressif/arduino-esp32, idf-update branch)
    M5Stack/            (clone of https://github.com/m5stack/M5Stack)
        component.mk    (should be modified. See below)
        ...
main/
    component.mk
    main.cpp            (copy of components/M5Stack/examples/Basics/Hello/Hello.ino)

The only tweak I did is the addition of src/utlitity to the end of these path variables in components/M5Stack/component.mk.

COMPONENT_SRCDIRS := . src src/utility
COMPONENT_ADD_INCLUDEDIRS := . src src/utility

Without this modification, make cannot correctly find the source codes and headers under src/utility.

The above setup looks OK and works for other projects.
My questions are:
* Is this a correct setup for ESP-IDF projects? (Is there any better one?)
* Is there any way to avoid the modification of components/M5Stack/component.mk?

Thank you for attention.

Since yours is working, it should be safe to assume your setup is correct: with M5Stack-IDF installed in the ESP-IDF directory.

Thanks for the update....

In my setup the M5Stack-IDF is in esp-idf.

I achieved to run esp-idf hello-world example on the M5Stack but I need to use M5 specific functions, hence the need for M5Stack.h I guess

The content of hello_world is (sorry indentation is not kept by this site FAQ engine):

build/
components/
arduino/
appveyor.yml
boards.txt
component.mk
cores/
docs/
Kconfig
libraries/
Makefile.projbuild
package/
package.json
platform.txt
programmers.txt
README.md
tools/
variants/
main
component.mk
hello_world_main.c
Makefile
README.md
sdkconfig
sdkconfig.old

I'll keep on tomorrow

I checked my ESP-IDF and i still have setup issues.

Under Windows, I have the ESP-IDF directory and the M5Stack-IDF directory both installed in their own separate directory located at: c:\Users\myusername

I set this up many weeks ago so I don't recall what led me to install the directories there or if that is correct.

RE - Your last error message: "when trying to use M5.xxx functions, the #include <M5Stack.h> yields in a missing M5Stack.h message."

This is where I have that file located:
C:\Users\myusername\M5Stack-IDF\components\M5Stack\src\M5Stack.h

I don't suppose it gave you any suggestion where it expected to find this file ?

Which OS are you running ?

Thanks for adding the links. They will be useful.

Now, make menuconfig has Arduino options.
I had followed
https://github.com/m5stack/M5Stack-IDF
which lacks some parts of
https://github.com/m5stack/M5Stack/blob/master/docs/esp-idf_component.md

But now, when trying to use M5.xxx functions, the #include <M5Stack.h> yields in a missing M5Stack.h message.

I keep searching to solve the issues

As per the M5Stack documentation (https://github.com/m5stack/M5Stack-IDF), make menuconfig should have some Arduino option ... but I don't see any
All other compilation issues could stem from this initial installation/configuration mistakes on my side.

Any idea ?

TIA for your help !

When building with esp-idf you can use M5Satck just like any other ESP32 development board.
All esp-idf examples, for example, will run on M5Stack same as on any other board.

You may have some issues when using C++. Please cunsult the documentation and ESP32 forum. There are many threads related to C++ issues/questions.

Using ESP-IDF a few weeks ago, I also got errors at compile time but I think they may have been to do with my setup, rather than a report of missing libraries. Haven't had time to revisit.

You are probably also familiar with the help at this link: https://esp-idf.readthedocs.io/en/latest/

I did a search and found at this link (https://github.com/espressif/esp-idf/releases/tag/v1.0) the following comment:

"ESP-IDF can only be used when cloned as git repository. Downloaded .zip archive is not functional because it doesn't contain submodule dependencies."

Did you install ESP-IDF via ZIP download via the link you mentioned ?

If yes to that and if the statement above is accurate, then that could be explain it. But there could always be other reasons........

@jimit
Thank you for your message.
Indeed, I have already written SW fo ESP32 (WRover kit) with ESP-IDF and I would like to do the same with M5stack.
Yes, I have read the following help : https://github.com/m5stack/M5Stack/blob/master/docs/esp-idf_component.md
but at compile time, some librairis are reported as missing.

Did you succeed in this same endeavor ?

Rgds

Which programming environment you are wanting to use ?

ESP-IDF , Micropython , Platformio , Eclipse

If new to ESP32 is probably best to start with Arduino and move on to others from there.

There are install notes at the link below, but I assume you've already viewed this:
https://github.com/m5stack/M5Stack

you mean with micropython? you will need to have that firmware flashed on it. i havent done that yet but i remember reading about it on the github i believe
