Thank you for your time and help yuyun2000!

I am using ArduinoIDE. I have attempted to setup PlatformIO, but I was not able to find any information on setting up PlatformIO for the Tab5. I also tried UIFlow2, but when I tried to use M5Burner to load the firmware on the Tab5, it would just display a window with no firmware options.

I tried the simplified code. I do not know how to trigger BtnA.wasPressed, so I copied the Keyboard.print and Keyboard.write to the end of the setup function.

This code does work OK for the Cardputer, but there is no keyboard output when using the same simplified code with the same usb cable on the Tab5.

I have tested this on the Tab5 with the battery attached, but there is still no keyboard output.

I have only been able to get ArduinoIDE working so far, and I have attempted setting up ArduinoIDE on a new Fedora installation with the same results.

Has anyone been successful in getting OTG HID keyboard output from the Tab5?

I am attempting to use Tab5 to send keyboard events through a usb connection. I am able to use similar code to send keystrokes when using a Cardputer. I took the touch button example and added keyboard print(string) and write(keycode) to the button event. I also tried adding a delay after calling keyboard.begin()

Using the same cable connection, the Cardputer successfully sends keyboard events to the computer, but the computer does not seem to receive any events from the Tab5.

Is any way I can try to debug this?

#include <M5Unified.h>
#include <M5GFX.h>

#include "USB.h"
#include "USBHIDKeyboard.h"

m5::touch_detail_t touchDetail;
static int32_t w;
static int32_t h;

LGFX_Button button;

USBHIDKeyboard Keyboard;

void setup() {
  M5.begin();

  w = M5.Lcd.width();
  h = M5.Lcd.height();
  
  M5.Lcd.fillScreen(WHITE);
  M5.Display.setRotation(0);
  M5.Display.setTextDatum(top_center);
  M5.Display.drawString("Button Released", w / 2, 0, &fonts::FreeMonoBold24pt7b);

  button.initButton(&M5.Lcd, w / 2, h / 2, 200, 200, TFT_BLUE, TFT_YELLOW, TFT_BLACK, "BTN", 4, 4);
  button.drawButton();


  Keyboard.begin();
  USB.begin();
  delay(4000);

  M5.Display.drawString("usb done", w / 2, 100, &fonts::FreeMonoBold24pt7b);
  
}



void loop() {
  M5.update();
  touchDetail = M5.Touch.getDetail();

  if (touchDetail.isPressed()) {
    if(button.contains(touchDetail.x, touchDetail.y)){
        M5.Display.drawString("Button  Pressed", w / 2, 0, &fonts::FreeMonoBold24pt7b);
        Keyboard.print("hello");
        Keyboard.write(KEY_RETURN);
        delay(2000);
    }
  }
  else {
    M5.Display.drawString("Button Released", w / 2, 0, &fonts::FreeMonoBold24pt7b);
  }
}
