Huzzah32 -asp32-Feather I2C pin missmatch

Hi,

The pin-layout on the Huzzah32-ESP32-Feather specifies that the ports for I2C is SDA = 23 and SCL = 22.

How ever using the code below I get SDA = 21 AND SCL=22. So my question is where is these values defined? I read somewhere on the internet that these are hardcoded i the hardware, is that correct or can I change them? In that case where can I find them? Or is this a "bugg" in the board?

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println(SDA);
  Serial.println(SCL);
}

void loop() {
  // put your main code here, to run repeatedly:

}

Thanks in advance

Found the problem. Must have been tired...

If I choose the correct board in Audrino I get the correct pins. Dho :o

Tip to anyone having problems, sleep on it and it will probably come to you.
