    Dimmer issue

    hi, i have this code int AC_LOAD =RED_LED ; // Output to Opto Triac pin int dimming = 128; // Dimming level (0-128) 0 = ON, 128 = OFF void setup() { pinMode(AC_LOAD, OUTPUT);// Set AC Load pin as output attachInterrupt(1, zero_crosss_int, RISING); // Choose the zero cross interrupt # from the table above } // the interrupt function must take no parameters and return nothing void zero_crosss_int() // function to be fired at the zero crossing to dim the light { // Firing angle calculation : 1 full 50Hz wave =1/50=20ms // Every zerocrossing thus: (50Hz)-> 10ms (1/2 Cycle) For 60Hz => 8.33ms (10.000/120) // 10ms=10000us // (10000us - 10us) / 128 = 75 (Approx) For 60Hz =>65 int dimtime = (65*dimming); // For 60Hz =>65 delayMicroseconds(dimtime); // Off cycle digitalWrite(AC_LOAD, HIGH); // triac firing delayMicroseconds(10); // triac On propogation delay (for 60Hz use 8.33) digitalWrite(AC_LOAD, LOW); // triac Off } void loop() { for (int i=5; i <= 128; i++){ dimming=i; delay(10); } } but i dont know in which pin i have attached the interrupt, somebody can explain me in which pin its the attachinterrupt?

    Matlab problem

    Hi everybody again, now i need all the comunity to help me... i need to read a single pin on my launchpad and plot those information in matlab, somebody can help me to do this?? i read in arduino playground a piece of code to call analogread() from matlab, with lauchpad its the same or what can i do to do this?
