I was about to write my own JSON serializer for my Feather project in C++. Went on GitHub -> Your lib -> Your blog -> Your channel -> this video. Subbed! / fellow IOT / embedded dev
there is only ONE problem with your channel my friend: you should have put 500 such videos there! I already bought your book - super nice - but still videos are very useful ;-)
As far as I know, only the AVR core disabled the support for %f, so the UNO, Yùn, Nano, and Mega won't support it. All other boards (including ESP8266, ESP32, and ARM) should support %f.
You can re-enable the %f support on AVRs (since it is deactivated to save a bit flash memory) by adding the following linker flags: -Wl,-u,vfprintf,-lprintf_flt
@@BenoitBlanchon je comprends. J'ai une question aurais tu des ressources (livres ou sites) pour bien coder en ce++ sur l'arduino. Je m'explique. Je suis relativement a l'aise en python et en go j'arrive à bien structuré mon code pour faire des projet conséquent mais pour arduino bien que je maîtrise un peut prêt le ça++ de base je galère à trouver le bon workflow du fait que ce++ ne soit pas du tout dogmatique.

Bref c'est un peu compliqué de poser la question sur youtube mais je suis un peu coincé (as tu un serveur discord?)
you should put an ads in your video i don't even mind
you explain it really clearly, there's so much effort to this
thank you for making this

These videos require a log of time and energy. I'm delighted to see that people appreciate them.
This video just helped me a LOT! Thank you very much for the clear and slow buildup of the different print functions. Amazing video!
Wonderful. Loved the way you put it together. Would love to see more of such gems.
Absolutely amazing video! You explain everything so well. You deserve many many more views.
The only one who knows what to do. Great video!
To bad you do not have other videos. You have the ability to explain things in a very clear way.
Excited, excellent explanation thank you
Great explaination! Thanks very much!
excellent videos and extremely well explained with visuals. Pls do more ;-)
Thank you so much, your vieo is well made and very usful!
amazing, it was really helpful dude, thanks a lot.

which book
@@piuselectronics5707 check his webpage ;-)
great video !! thank you man
Félicitation Benoit :)
Very helpful
Excellent. Thank you.
Q. What other Arduino boards accept %f?
As far as I know, only the AVR core disabled the support for %f, so the UNO, Yùn, Nano, and Mega won't support it.

Tu continues cette chaîne ?
En théorie, oui. En pratique, je n'arrive pas à trouvé le temps.

ı am going to sleep Zzz..
This one is the truly holy grail : snprintf_P(s, sizeof(s), PSTR("%s is %i years old"), name, age); it made my code work again. Thanks!
