Arduino 33BLE Timer3

Hello Everyone,
I am stuck with a time interruption problem on the arduino 33 BLE
for teensy board i was using TimerThree.h
For the Due board i was using DueTimer.h
but for the 33 BLE i tried Mbed. h with ticker but it does not work .
Is there any library which can do several timers on the 33 BLE
Thanks a lot :slight_smile:

code tested on nano 33 BLE,
this code is compiling but not working :confused:
I am investingating on the github arduino forum GitHub - arduino/ArduinoCore-nRF528x-mbedos: [Archived] Arduino core supporting mbed-enabled boards
i am using Arduino 1.8.10 with nRF528 1.1.6 installed

#include "mbed.h"
mbed::Ticker Timer36;
void setup()
{

// debug output at 115200 baud
SerialUSB.begin(115200);
//while (!SerialUSB) ;
Timer36.attach(timer3Handler,1);
Serial.print("timerattached");
}

void loop()
{
Serial.println("I am alive");
delay(1000);
}

void timer3Handler()
{
Serial.println("tic tac");
}

I modified the code,

#include “mbed.h”
mbed::Ticker Titi;
void setup()
{

// debug output at 115200 baud
Serial.begin(9600);
while (!Serial) {;}
Titi.attach(TitiHandler,10);
Serial.print(“timerattached”);
}

void loop()
{
Serial.println(“I am alive”);
delay(1000);
}
//
void TitiHandler()
{
//Serial.println(“tic tac”);
}

when i uncomment the line in Titihandler, it compile but everything freeze…
whith the line commented it compile and is alive …
maybe it comes from mbed.h??
any Clue is welcome :slight_smile:
