Joystick.h and Keyboard.h no more compatible

[baritonomarchetto]

This gave me some headache recently. I was used to merge these two libs toghether with no problems and after one year stuck with an old version of pi pico core I decided to update...

They are no more compatible. You can check it with this simple sketch:

//Short pin 10 to ground and joy button 1 will be pressed

#include <Joystick.h>
//#include <Keyboard.h>

const byte btn = 10;

void setup (){
  pinMode(btn, INPUT_PULLUP);
  Joystick.begin();// start joystick
} 

void loop (){
  Joystick.button(1, !digitalRead(btn));
  delay(8);
}

This one works. Uncomment Keyboard.h and it will not work. The issue arose between ver 3.1.0 and 3.1.1

Hm, the core does try to accomodate the Joystick + Keyboard case in its USB code, even in the latest version.

https://github.com/earlephilhower/arduino-pico/blob/3068cd0af004e2575f9d47b0851f3abab64124dc/cores/rp2040/RP2040USB.cpp#L166-L177

so maybe something broke somewhere else..

Do I understand it correct that "it will not work" means the USB setup fails or only shows on USB device instead of two? Or do both USB device show up in the device manager but the joystick doesn't report button presses?

I just tried the Joystick-Alltest.ino example and added #include <Keyboard.h> and it seems to work just fine.

The example you posted also works fine (I replaced the pin /wBOOTSEL for simplicity). No issues seen at all:

#include <Joystick.h>
#include <Keyboard.h>

const byte btn = 10;

void setup (){
  pinMode(btn, INPUT_PULLUP);
  Joystick.begin();// start joystick
} 

void loop (){
  Joystick.button(1, !BOOTSEL);
  delay(8);
}

Please explain exactly what the issue you're seeing is, because it's not reproducible here...

Thank you both for your replies. The issue I see is that on windows 10 to monitor the emulated gamepad using joy.cpl, a button press is not recorded when keyboard.h is included. Rolling back to versions <= 3.1.0 the button press is recorded. I will try another joystick functionality check program but this used to work

[earlephilhower]

Your problem is you're using a version 3.1.1 that's about a year old with bugs that were fixed in the subsequent 3.2.0 version (also about a year old) per the release notes. Use the latest 3.6.2 release. Just tested the sketch on Win 11 w/the current core and no issues reporting the joystick data.

[baritonomarchetto]

Sorry to bother, maybe I was not able to describe the issue or I am not understanding well your answer :)

If I use rel 3.6.2, win 10 joypad monitor (joy.cpl) shows no activity when I press a button if keyboard.h is included. It shows button press if I comment keyboard.h. Release 3.1.0 (and before) works in win10, instead, even with keyboard.h included.

I would absolutely prefer to use the latest release, but it's not working as it should in my understanding.

Could it be a win 10 issue then?

I will also try an online joypad activity monitor tomorrow.

Hope I was more clear now, thank you very much for you time!

[earlephilhower]

I just took the USB cable down to a Win10 laptop, same as was on Win 11. No issues seen, button flicks when I hit BOOTSEL. I'm sorry, but it's not reproducible and there haven't been any reports like this since before the 3.2.0 fix.

[maxgerhardt]

OP might have a weird state of the Arduino-Pico core files with a half-botched update process. Maybe try a clean remove of the core (+ deletion of the rp2040 packages from the Arduino IDE intstall folder) and a clean reinstall.

[baritonomarchetto]

Thank you very much for the help!

I made further testings and spotted the issue. Someway, the program I used to monitor joypad activity (joy.cpl) is no more compatible. My first thinking was a win32 related issue. It's not being that some other win32 programs work.

Other online gamepad monitors record the button press with no issues.

Thanks for closing the loop here!
