Keyboard and ESP32-S3-Zero

[Electrof]

Hello,

I have as project to simulate keyboard with a ESP32-S3.
In Arduino IDE, I hav already installed Adafruit TinyUSB Library and ESP32TinyUSB.
My config concerning my board :

Here a short code to simulate the pressing of A character :

#include <Adafruit_TinyUSB.h>

Adafruit_USBD_HID usb_hid;

void setup() {
    Serial.begin(115200);
    usb_hid.begin();
    while (!TinyUSBDevice.mounted()) {
        delay(100);
    }
    Serial.println("USB HID initialized and mounted");

    // Test envoi d'une touche
    delay(1000); // Attendre avant d'envoyer
    sendKey('A');
}

void loop() {
    // Vide
}

void sendKey(char ch) {
    uint8_t keycode = HID_KEY_A; // Envoie simplement la touche 'A'
    uint8_t modifiers = 0;

    Serial.println("Sending key press...");
    usb_hid.keyboardPress(keycode, modifiers);
    Serial.println("Key press sent.");
    delay(100);
    usb_hid.keyboardRelease(keycode);
    Serial.println("Key released");
}

The ouput of Serial Monitor :

3:51:22.850 -> Sending key press...Sending key press...Sending key press...Sending key press...

For each "Sending key press...", the ESP32S3 reboots. And I don't have the ouput string 'USB HID initialized and mounted', so it seems the TinyUSB is not mounted, but the while loop is finish

Can you help me please ?

Thank you
