Description
I am trying to define the reset pin for my adafruit pressure sensor (Adafruit_MPRLS).
I am trying to do something like:
#define RESET_PIN -1 // set to any GPIO pin # to hard-reset on begin()
#define EOC_PIN -1 // set to any GPIO pin to read end-of-conversion by pin
Adafruit_MPRLS mpr = Adafruit_MPRLS(RESET_PIN, EOC_PIN);
but I do not know what to put instead of -1 since there is no gpio pin for the reset pin on the esp32

* A basic test of the sensor with default settings
*
* Designed specifically to work with the MPRLS sensor from Adafruit
* ----> https://www.adafruit.com/products/3965
*
* These sensors use I2C to communicate, 2 pins (SCL+SDA) are required
* to interface with the breakout.

// You dont *need* a reset and EOC pin for most uses, so we set to -1 and don't connect

Adafruit_MPRLS mpr = Adafruit_MPRLS(RESET_PIN, EOC_PIN);

}Debug Message
there is no message since I do not know what to put, so I did not run anything
