Help with Arduino Uno with HoodLoader2 (pin issue?)

[stevealexandre]

Hi everyone,

I have flash my uno with hoodloader2 but trying to use the keyboard still not working.
When I'm pressing the button, the text is not print and nothing happen.

• Here my sample code :

#include <Keyboard.h>

void setup() {
  // make pin 2 an input and turn on the
  // pullup resistor so it goes high unless
  // connected to ground:
  pinMode(2, INPUT_PULLUP);
  Keyboard.begin();
}

void loop() {
  //if the button is pressed
  if (digitalRead(2) == LOW) {
    //Send the message
    Keyboard.print("Hello!");
  }
}

• Here the target circuit :
  

• As you can see on Windows, it's reconized as HoodLoader2 :
  

I'm beginner on arduino but my build for me seems ok.
The final objectif for me is to have an hand push to talk button :).
On the HID github, he told me i'm using the wrong pins for the wrong mcu but I have tried many pins and same result.

Thanks.

It does not help if you open the issue again. You need to use the 4 pin header of the 16u2, not the "normal" arduino pins.

You must understand, that you are controlling 2 MCUs now, not a single one.
