Set up Travis build

@dogmaphobic Volunteering to help with that.

The build itself is setup and working. I just need to figure out where to upload the binaries.

@dogmaphobic do you need any help to integrate this repo with Travis?

[dogmaphobic]

It's already there, thanks! :) At least the build. What's missing is an automated way to make the distribution available. I also need the Build Number to come off Travis instead of having to manually edit it each time.

What's missing is an automated way to make the distribution available.

PlatformIO allows uploading of existing firmware without project rebuilding and project source code.

1. Place firmware to .pioenvs/esp12e/firmware.bin
2. Upload it using platformio run -t uploadlazy -e esp12e --disable-auto-clean.

In this case, PlatformIO will install only the upload tools without toolchains, frameworks, SDKs and etc.

I also need the Build Number to come off Travis instead of having to manually edit it each time.

Could you explain in details?

[dogmaphobic]

What I meant was to find a place where to put the resulting binary so people can download it. Right now I'm manually building and uploading to my own server and updating the link here:

https://pixhawk.org/peripherals/8266

Regarding automated build numbering, I just need to write a script that reads the current Build Number off some text file, increments it, and saves it back (to the repository). It would then generate a header file with the build number instead of it being hard coded here:

https://github.com/dogmaphobic/mavesp8266/blob/master/src/mavesp8266.h#L64-L67

P.S. For what t's worth, for distribution, I use -e esp01_1m

PlatformIO is very powerful, flexible and easy for use Build System. Also, Travis provides environment variables. You need TRAVIS_BUILD_ID.

Why do you need this extra script? https://github.com/dogmaphobic/mavesp8266/blob/master/esp_extra.py . You can use upload_resetmethod instead overriding.

The final platformio.ini without extra scripts

[env:esp01]
platform = espressif
framework = arduino
board = esp01
upload_speed = 921600
upload_resetmethod = nodemcu
build_flags = !echo "-DBUILD_ID="$TRAVIS_BUILD_ID

Then, you can upload firmware to your own server or, for example, to @bintray. See https://docs.travis-ci.com/user/deployment/

Believe me, I thank PlatformIO every day :) I've been writing my own mess of Makefiles handling all these different platforms for years. When I first heard of PlatformIO it was a dream come true.

You need TRAVIS_BUILD_ID.

Yes, I have not spent any time dealing with this. I figured Travis would have something but I was worried it would be some large (> 16 bits) number. I currently use a 8+8+16 scheme (into a 32-bit number) to save the full version. While googling that, I found the page with all the variables. TRAVIS_BUILD_NUMBER might be something to look too. As I said, I have not had the time to look at any of this yet.

That came about because at the time, by default PlatformIO would not properly reset the ESP12 I was using. A quick search on google pointed to that solution, which I used and it just worked. That all happened within a couple of hours of first hearing about PlatformIO and I have not spent much time thinking about it since.

Then, you can upload firmware to your own server or, for example, to @bintray. See https://docs.travis-ci.com/user/deployment/

My own server is actually my own, personal server, not some general hosting service. I would need to setup an account with some place so Travis could upload the binary automatically. I cannot allow Travis to upload anything to my own sever. Again, I have not had the time to think about any of this.

Thanks!

[ivankravets]

Yes, TRAVIS_BUILD_NUMBER is better for you. The last value is 45.

In any case, thanks a lot you that use @platformio! Don't hesitate to contact us for the other questions.

Ivan, thank you for putting together such a polished system. I really like what you guys built. Everything "just works"!
