Basicamente esto en un arduino uno se lo hace puenteando o uniendo dos pines de la placa para ponerla en modo DFU pero en la Wavgat uno r3 esto no se como hacerlo, por favor alguien me da una mano? muchas gracias desde ya
Basically this in an arduino one is done by bridging or joining two pins of the board to put it in DFU mode but in the Wavgat uno r3 this I don't know how to do it, please someone give me a hand? Thank you in advance
It's possible to do this on the official Uno (or faithful clones) because the ATmega16U2 chip used as a USB to TTL serial adapter on those boards can be programmed with a custom firmware. Often the Chinese "Uno" derivatives use an application-specific chip for this purpose, rather than a general purpose microcontroller like the ATmega16U2, and it is not possible to reprogram those chips with a custom firmware.
So to answer your question for sure, we would need you to tell us which USB to TTL serial chip is used on your board. It will be written on the top of the largish black chip near the USB jack on the board. The most common one is the CH340. If you can't figure it out, you could post a link to where you bought the board from, though WAVGAT has been known to provide incorrect information in their product listings, so I'm not sure we can trust that information.
I've deleted/merged your other cross-post(s) @GabrielNicolau.
Cross posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.
Repeated cross posting will result in a suspension from the forum.
In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum board. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
First, I apologize for the publications that I did not know I could not do, now I thank you for taking part of your time to answer me, on my board there are two chips, one is square and says "wavgat avga 328p", the other one that is rectangular "ch340g". I hope you can answer me and thank you very much, sir.
Unfortunately, you can't do joystick emulation with that board because it has the CH340 instead of the ATmega16U2.
My advice would be to get a board with a primary microcontroller that has native USB capabilities. Those are the boards that use the ATmega32U4 (e.g., Leonardo, Micro, Pro Micro), and the SAMD boards (e.g., Zero, MKR boards). The reason I recommend those over an Uno or Mega with the ATmega16U2 USB to TTL serial chip is that the DFU process is a little bit more complicated. With the native serial boards, you just upload your sketch as usual. That said, if you are trying to follow a tutorial that is written for the Uno then it won't apply to a native USB board.
God, if I had known before, I would not have acquired this crap, thank you very much for taking some time to respond, greetings
You're welcome. I'm glad if I was able to be of assistance. Although the board may not be of use for your current project, it could still be great for some other things that don't require HID functionality, so maybe you'll still find use for it.
Enjoy!

Is unfair to say crap, the board is a more or less Uno compatible board and it does what it should do. With an original uno you would have the same trouble.
It is up to you to fetch enough information before buying.
ElEspanol:

This is incorrect. Although I don't recommend it, you can do HID on the official Unos and Megas by changing the firmware on the ATmega16U2 chip those boards use. Here's some information (though not necessarily the exact project @GabrielNicolau was planning to do):
But I also agree that the Uno derivatives with the CH340 are not "crap". It is kind of cool that you can change the firmware of the ATmega16U2 on the official Uno, but probably only 0.001% of the Arduino users ever do that. The derivative makers use the CH340 instead of the ATmega16U2 because it is a lot cheaper and it works as well (except for the difficulty finding the driver) for the purpose of acting as a USB to TTL serial adapter.
Por favor ElEspanol, el hilo esta aca desde el mismo 7/12 por lo tanto no importa si un moderador en inglés escribe en ese idioma, tu debes hacerlo en castellano.
Ahora hablaré con el moderador en ingles por la misma razón ya que si para ellos es una falta hacerlo en su foro, también lo es en este foro.
@pert y @Elespanol, estan en el foro en Espanol, de modo que usen el idioma espanol.
A ambos les pido traduzcan sus respuestas ultimas o usen Google Translate.
@surbyte normally I would respect that, but this was originally posted in the English section by @GabrielNicolau, so I reply in English.
