Ok, I've finally found some way to do it. I've made a modification in The PWM write Pin VI to add a 4th Command. So now i use a 16bit number as the set value that i split into two 8bits words with an AND fonction. So i now have one 8 bits word and another one with only 2 significants bits.
In the Arduino code, I use this fonction "Timer1.pwm(command[2],(4 * command[3]+command[4]))" to reassemble the two 8bits words as a 10bit set value. That works fine, here is the 16 to 2*8bits VI and arduino code for the case, maybe it will help somebody else.
case 0x0A: // PWM Write Pin
// Define output pin, and its mode
pinMode(command[2], OUTPUT);
// Initialize
Timer1.initialize(5000); // initialize timer1, and set a 1/2 second period
// Note that this breaks analogWrite() for digital pins 9 and 10 on Arduino.
Timer1.pwm(command[2],(4 * command[3]+command[4])); // setup pwm on pin X
Serial.write('0');
break;
Thanks for answering me.
