@mfalkvidd that is pretty nifty. I need to figure out how I can use this. Thanks for keeping this discussion active. Little things like that have the possibility of saving even more power.

@zboblamont would you please direct me to the table/array method. I can imagine a few approaches, but am very interested how you have it set up. Thanks!

@artag I don't know how to do that generally.

A quick look at the results of:

pio device list

will get you the information to insert into platformio.ini. Their doc is pretty good. Maybe try it to the serial id. I haven't gotten so advanced yet. They have some nice examples.

That's funny. I can't stand the Arduino IDE for the same reason. I have to remember where to get a dependency from which menu, select the correct port, and deal with a different editor than I am used to. I also didn't like how it would doctor the code with function declarations etc. It's C++. Why hide that fact? Sure, beginner-friendly is nice and it helped me for blinking LEDs, but afterwards it was annoying. Now I am pretty fast when working with a new board.

CLI to create a web-based tool that can flash simple sketches.
That sounds a little funny. So you want to have your web browser (indirectly) accessing hardware ports or at least determining the correct port? I guess that would be ok. I have a bunch of extensions which may not be so secure. I guess for beginners that would be nice. How would you deal with library dependencies? I guess the CLI tool would be advanced enough for that.

If you are used to python the CLI from platformio is pretty simple. I guess my approach is for those who write code for a significant portion of their day.

@oneyb said in Arduino has an official CLI app now:

$EDITOR platformio.ini src/*cpp

You missed a bit of 'digging' :).

I cleaned up the code and pushed it so it will compile, but eventually you will want to dig. Blinking an led gets old.
Pull in my changes please and then it will compile for you. Then you can start with some fun.
If you like it, a possible workflow is to fork it and rename it to whatever. As you wish. I hope it helps.

No, I haven't. I guess I don't plan on it either. Have you heard of platformio?

It's pretty damn handy. For those that wish, it has a better IDE than Arduino, fetches dependencies as specified, and above all has a great CLI. If you're interested in compiling and uploading binaries from the CLI, I would recommend you have a look at:

https://docs.platformio.org/en/latest/core.html

I know it doesn't answer your question, but I like to have a proper C++ linter running, letting a computer work for me, documenting exactly what I did to get code compiling and uploading, and to edit code in a proper editor.

A quick start with platformio could be:

pip install platformio
git clone https://github.com/oneyb/template-mysensors-platformio blink
cd blink
# Do some stuff
$EDITOR platformio.ini src/*cc
# and finally:
pio run -t upload

I hope that helps you to be more efficient. It sure has helped me.

Hi @mfalkvidd,

I can't find anything about writing tests. I see you have mentioned tests for building on different hardware. That's pretty neat. Did you document you testing infrastructure. I would be very interested in how you set that up. I imagine it being a pretty messy job.

I find it helpful to have a policy on testing code.

Cheers

Hi @mfalkvidd,
thank you for the encouragement. My dream is to become proficient in small-scale industrial applications. For example, I would like to build a kitchen countertop food processor to process larger batches of fruits, pour them in (recycled) glasses in a protected sterile atmosphere, and seal them. Basically it would be a canning machine for the lazy :).

For now I want to apply my c++ skills.

The contribution guidelines are great, especially regarding coding style.

I'll have a look at the issues.

Hello there,

I have been brushing up on my c++ skills lately so that I can be more adept with embedded systems programming.

I would like to contribute to MySensors and would like some guidance on where help is needed.

I see there are a few things here:

@yveaux

nice tip; I am still getting into the proper mindset for memory conservation.

To be clear, do you mean the following?

void loop(){
  // for example
  float fgehum = myHumidity.readHumidity()
  send( MyMessage(CHILD_ID_FGEHUM,  V_HUM ).set(fgehum) );
...
}

Also, @mfalkvidd, why would you prefer to declare a MyMessage object instead of on the fly? I guess that there's overhead for creation of the object anew everytime. So there would be powersavings due to having a single and MyMessage object and then reusing it. Am I in the ballpark?
