I didn´t understand why I am receiving errors messages about USB port. Should it be part of Arduino Framework (Arduino.h)?

#include <Arduino.h>

/função setup/

{

// void IniciaLEDsSerial(void);

Serial.begin(115200);

delay(5000);

Serial.println(“TESTE DE IMPRESSÃO NO SETUP”);

}

/função loop/

void loop()

{

// void PiscaLEDs(void);

Serial.println(“TESTE DE IMPRESSÃO NO LOOP”);

delay(2000);

Hi @crmrosa ,

Please add this #include <Adafruit_TinyUSB.h> on top of your code…

In your previous codes, it is likely you do not encounter the error because you are using the Wire library.

Thank you, I already did and it is working fine.

Do you know why the standard library <Arduino.h> is not enough to support a RAK4631 USB-C port?

I am not really familiar on the exact reason but this happen after the update of the adafruit bootloader. @beegee might be able to recall this part and explain more clearly.

For an answer to this question, please ask Adafruit. Our BSP is using the Adafruit nRF52 BSP, the only change is that the RAK4631 is in it as a variant.
Adafruit decided to take the USB library out of the BSP’s built-in libraries and add it as an external library. That is causing the problem with “missing header file”.

Thank you by your explanation.
