issue with I2C on pico (initialization)

Try with an extra timeout

function ledInit() {
  digitalPulse(LED1,1,200);
  digitalPulse(LED2,1,400);
}
//function onInit() {
E.on('init',function() {
  setTimeout(function() { // extra timeout
    USB.setConsole();
    console.log('ini');
    ledInit();
    setTimeout(ledInit,2000);
  },1500); // extra timeout (try'd 1000 but did'n work)
}); // end E.on()
//} // end onInit()

// onInit(); remove before save
