Using a SparkFun Pro Micro as a Nintendo Switch Controller

Projects General Guidance
1

I am using a Sparkfun Pro Micro for this project, along with Arduino IDE 2.3.2

I am using the NintendoSwitchControlLibrary from this link below:

This is my biggest problem with my project, I have been working on it for a few weeks now and I cannot go forward with it until I get it to work. My main issue is I cannot get my board to connect to my Nintendo Switch at all, which causes nothing to happen. What I want it to do is to connect to my Nintendo Switch once plugged in (Right now I have it so I'll plug it in once I am on the change Grip/Order screen on my switch). Then once it does this and connects it will press the A button on my Nintendo Switch every second (approx.)

#include <NintendoSwitchControlLibrary.h>

//Before plugging in go to change grip/order to allow pro micro to connect

void connectBoard() {
  delay(10000); //Delay to allow board to connect once plugged in
  pushButton(Button::L, 5000);
  pushButton(Button::R, 5000);
}

void rapidPress() {
  pushButton(Button::A,500); //Press the A button every half second
}

void setup() {
  delay(5000); //Extra time for controller to connect

  connectBoard();
}

void loop() {
  rapidPress();
  delay(1000); //Wait 1 second before pressing again
}

Edit: I made sure to install the SparkFun AVR boards, and am uploading to my Sparkfun Pro Micro.

Edit: I am not using bluetooth, I am using the USB cord through either the dock or switch's USB-C

I think you left out a lot of code. Does it not connect via Bluetooth? If it does you have two consider that Bluetooth is notoriously unreliable.

3

No I am connecting it through USB, either through the Dock or through the switch's USB-C

4

Ok, then post the entire code.

5

I have, the code I had sent is all of my code

6

In that case, the actual code is in the library. Either study that or raise a support issue with the library authors. I hope you are not in a hurry, open source fixes take a long time to happen if at all.

7

is it true that mentioned lib is only Leonardo compatible?

8

A Micro and a Leonardo are, I believe, functionally the same.

9

Easy enough to check, just look at the architecture setting in the library library.properties file.
I just looked and it is all architectures

url=GitHub - lefmarna/NintendoSwitchControlLibrary: A library for microcontrollers that uses Arduino to automate Nintendo Switch games.
architectures=*

I've heard a Micro and an Leonardo are practically the same. I'm relatively new to Arduino so I've been struggling with this. I've tried looking through the site with the info for the library, and thought I was setting it up right. Even tried to run an example code but could not get it to connect either. I do not know if I'm missing something, or if theres a step I'm leaving out (I am uploading the file lol, just figured I'd add that)

11

I remember a forum member trying to get something along these lines going last year (fruitless).
[ Here, a different library is used. ]

12

Is your controller a clone or the real deal. Another group I belong to did a similar project and those with clones had 100% failure while those who spent the big money worked.

13

For clarity - you're meaning the 'Micro', yes?

14

I am not using any form of actual game controller, I am using a simple Sparkfun Pro Micro.

15

Sorry, no. I was referring to the Nintendo.

16

Then I have no idea why that sketch will do anything.
Good luck.

I typically use google translate to translate it, by putting it's like there and setting it to Japanese to English

Main thing I notice is where it says Leonardo requires, but I'm thinking the Pro Micro is practically the same

20

Looking deeper into it I went to this website from the ReadMe section of the first link (Here's the google translated link)

It mentions needing to change something in the boards.txt or something

If anyone is experience with this and can help me figure it out it would be much appreciated

21

However looking at it they do it specifically for the leonardo, but Idk if it will look the same for pro micro

If you expect help, post the translation.
