arduino thread update volatile variable - multithreading

Question

I want to use multithread programming with Arduino.
I wrote some code ato update the variable tempsPose but it doesn't work (the led blinks always at the same speed).
How can I change the following code in order to update tempsPose variable in the function blinkled13 when this variable is mofified in the loop function?
#include <Thread.h>
Thread myThread = Thread();
int ledPin = 13;
volatile int tempsPose ;
void blinkLed13()
{
\\i would like the value of 'tempspose' to be updated
\\ when the value of the variable changes in the blinkLed13 function
while(1){
digitalWrite(ledPin, HIGH);
delay(tempsPose);
digitalWrite(ledPin, LOW);
delay(tempsPose);
}
}
void setup() {
tempsPose = 100;
pinMode(13,OUTPUT);
Serial.begin(9600);
myThread.onRun(blinkLed13);
if(myThread.shouldRun())
myThread.run();
}
void loop() {
for(int j=0; j<100; j++){
delay(200);
\\some code which change the value of 'tempsPose'
\\this code is pseudo code
tempsPose = tempsPose + 1000;
}
}

Examples are all "one-shot" (no infinite loops) and the code if (thread.shouldRun()) thread.run(); is inside of loop(). So I suppose it won't get into the loop() at all in your case.
For example more interactive code ('+' adds 100ms, '-' substracts 100ms):
#include <Thread.h>
Thread myThread = Thread();
int ledPin = 13;
volatile int tempsPose;
void blinkLed13() {
// i would like the value of 'tempspose' to be updated
// when the value of the variable changes in the blinkLed13 function
static bool state = 0;
state = !state;
digitalWrite(ledPin, state);
Serial.println(state ? "On" : "Off");
}
void setup() {
tempsPose = 100;
pinMode(13,OUTPUT);
Serial.begin(9600);
myThread.onRun(blinkLed13);
myThread.setInterval(tempsPose);
}
void loop() {
if(myThread.shouldRun()) myThread.run();
if (Serial.available()) {
uint8_t ch = Serial.read(); // read character from serial
if (ch == '+' && tempsPose < 10000) { // no more than 10s
tempsPose += 100;
myThread.setInterval(tempsPose);
} else if (ch == '-' && tempsPose > 100) { // less than 100ms is not allowed here
tempsPose -= 100;
myThread.setInterval(tempsPose);
}
Serial.println(tempsPose);
}
}
