Wifi Kit 32 shutting down when using display

When the board arrived, it was working well, wifi and screen.
I uploaded the classic blink and everithing was ok.

Now it was time to make the OLED work,
i’ve worked with them before but it was with an arduino pro micro,
after uploading the example, nothing worked, tested around and this is what i know:

  • the board boots
  • nothing appears on screen
  • the board resets when any Heltec.display method is called

need some help solving this :slight_smile:

When calling any Heltec.display method this appears on the serial monitor

Soooooo, I gave up on using Heltec normally,
imported the Heltec normally but im using SSD1306Wire.h directly
everything works normally now

#define WIFI_Kit_32
#include "heltec.h"
#include "WiFi.h"

SSD1306Wire factory_display(0x3c, SDA_OLED, SCL_OLED, RST_OLED, GEOMETRY_128_64);

void setup() {
