HI @Garrabrant
You're doing fine with the report.
However, your loop() code is possibly causing problem. I'll let you figure out yourself what's wrong and learn from that
Try this
#if ( defined(ARDUINO_NANO_RP2040_CONNECT) || defined(ARDUINO_RASPBERRY_PI_PICO) || defined(ARDUINO_ADAFRUIT_FEATHER_RP2040) || \
defined(ARDUINO_GENERIC_RP2040) ) && defined(ARDUINO_ARCH_MBED)
#define USING_MBED_RPI_PICO_TIMER_INTERRUPT true
#else
#error This code is intended to run on the MBED RASPBERRY_PI_PICO platform! Please check your Tools->Board setting.
#endif
// These define's must be placed at the beginning before #include "MBED_RPI_PICO_TimerInterrupt.h"
// _TIMERINTERRUPT_LOGLEVEL_ from 0 to 4

#include "MBED_RPi_Pico_TimerInterrupt.h"
#ifndef LED_BUILTIN
#define LED_BUILTIN 25 // Pin LED_BUILTIN mapped to pin GPIO25 of RPI_PICO, control on-board LED
#endif
#define PIN_D1 1 // Pin D1 mapped to pin GPIO1 of RPI_PICO
volatile uint32_t counter = 0;
// Never use Serial.print inside this mbed ISR. Will hang the system
void TimerHandler0(uint alarm_num)
{
static bool toggle0 = false;
///////////////////////////////////////////////////////////

// Interval in microsecs
if (ITimer0.attachInterruptInterval(TIMER0_INTERVAL_MS * 1000, TimerHandler0))
{

Serial.println(millis());
}
else

}
and it's still running, LED blinking and outputting to O-Scope after several hours

Thanks, @khoih-prog
Your code works fine for me. I'll try to figure out what I did wrong.

@khoih-prog Can you try only running your ITimer1 and not start ITimer0? I found when I did this, your code stopped calling the Timer1 interrupt at 5640 seconds.
Or is it important that both interrupt timers must be run at the same time?

I really don't believe this yet. As I'm travelling now and have no time to test / verify your claim.
If this is true, there must be something very wrong with the mbed_rp2040 core.
Post the issue on mbed_rp2040 core, if you have time and still interested.
I suggest you test and move on to RPI_PICO_TimerInterrupt library and IMHO, better core arduino-pico

@khoih-prog I'd appreciate it if you could, when you have time, confirm you can reproduce my problem when you only use ITimer1 and just delete the ITimer0 code. If you cannot reproduce it, I'll know it is something odd on my end. Thank you!

Hi @Garrabrant
Sorry I'm so busy right now to create many new libraries and have no time to spare. You can try using arduino-pico core
If OK then, raise the issue in ArduinoCore-mbed, certainly with correct MRE

Thank you @khoih-prog I really appreciate your taking the time to confirm.
FYI, I learned that if I change MBED_RPI_PICO_Timer ITimer1(1); to MBED_RPI_PICO_Timer ITimer1(0); the problem seems to go away (at least for the first 15 hours).
I'm building with Platform.IO and I don't remember if I was given the option of a non MBED arduino pico core. Is it easy to switch to arduino-pico?

HI @Garrabrant
It can only be explained that mbed_rp2040 core is using Timer1 for some purpose, periodically, and disrupts your Timer1 operation when it takes over the timer.
You can post the question on Arduino mbed_rp2040 core as I don't have time to investigate further to see where the Timer1 is used.
For your use-case, why not selecting another TImer to use (RP2040 has 4 hardware timers) instead of sticking to Timer1.
As a rule, when select a Timer to use, it must not be used by other purposes, especially the higher-priority core
