ESP32-Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled

Hi,

I've converted code from Teensy to ESP32 and added an ADS1115 to this. The original code is here: Loftur E. Jónasson - TF3LJ / VE2AO - 15 - Power and SWR Meter, rev II See: [
PSWR_T_103.zip]

While I've managed to use the usual AI tools to assist me, I'm getting the error below:
Guru Meditation Error: Core 1 panic'ed (IntegerDivideByZero). Exception was unhandled.

Rebooting...

I have following libraries:

#include "PdBm.h"
#include <Wire.h>
#include "PSWRtft.h"
#include <Metro.h>
#include <esp_timer.h>
// Create a periodic timer with a period of one second.
// Create a periodic timer with a period of one second.
esp_timer_handle_t timer;

esp_timer_create_args_t timer_args = {
  .callback = powerSampler,
  .arg = nullptr,
  .dispatch_method = ESP_TIMER_TASK,
  .name = "my_timer",
  .skip_unhandled_events = true,

Thanks

can you use the ESP32 exception decoder to get more info from

that will tell you where the issue is (you should see a division by zero since it complains about IntegerDivideByZero)
