M5stack programming without Arduino IDE : how ?

[jrs]

@jimit
I am running Mac OS

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

@jrs Glad you seem to have it working.

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....

The easyest way to start with ESP-IDF is by PlatformIO
That IDE include ESP-IDF, Arduino, Mbed...

@calin Great tip re. PlatformIO - will take it for a spin...

Hello.
I started to use M5Stack a month ago. I tried several simple projects using Arduino IDE. Before moving to ESP-IDF based development, I tried a trivial (hello world) project to test my settings.

Unfortunately, current https://github.com/m5stack/M5Stack-IDF looks outdated and incomplete.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.

My forked and updated version (implementing the setup in my previous post) of M5Stack-IDF template project is available: https://github.com/wtakuo/M5Stack-IDF

@wtakuo Thank you!

I fixed my patch in https://github.com/wtakuo/M5Stack-IDF.

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.

[wtakuo]

Now my PR has just been incorporated into the latest commit of M5Stack. So I removed patch.txt.

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.

@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.

For reference:

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 :)
