I’m working on a sparkcore controlled light dimmer with using the PowerSSR tail and PowerZeroCross tail from powerswitchtail. I’m trying to modify the example arduino sketch they post on their website to work with the sparkcore. The sketch uses TimerOne.h to attach timer interupts but I don’t think there’s a library just yet for the sparkcore so I am using the alternative method of counting time in the main loop. This is the work in progress code I have but unfortunately it does not work.
unsigned long oldTime;
int i=0; // Variable to use as a counter
boolean zero_cross=0; // Boolean to store a "switch" to tell us if we have crossed zero
int PSSR = D5; // PowerSSR Tail connected to digital pin 4
int dim = 0; // Default dimming level (0-128) 0 = on, 128 = off
int freqStep = 60; // Set to 60hz mains
int LED = D7; // LED on Arduino board on digital pin 13
void setup()
{
pinMode(LED, OUTPUT);
pinMode(PSSR, OUTPUT); // Set SSR1 pin as output
attachInterrupt(D1, zero_cross_detect, RISING); // Attach an Interupt to digital pin 2 (interupt 0),
// Timer1.initialize(freqStep);
// Timer1.attachInterrupt(dim_check,freqStep);
oldTime = micros();
}
void loop() // Main loop
{
dim = 120;
fire_dim_check();
delay(500);
dim = 100;
fire_dim_check();
delay(500);
dim = 80;
fire_dim_check();
delay(500);
dim = 60;
fire_dim_check();
delay(500);
dim = 40;
fire_dim_check();
delay(500);
dim = 20;
fire_dim_check();
delay(500);
dim = 0;
fire_dim_check();
delay(500);
}
// Functions
void fire_dim_check() {
if((micros() - oldTime) >= freqStep) {
dim_check();
oldTime = micros();
}
}
void dim_check() { // This function will fire the triac at the proper time
if(zero_cross == 1) { // First check to make sure the zero-cross has happened else do nothing
if(i>=dim) {
delayMicroseconds(100); //These values will fire the PSSR Tail.
digitalWrite(PSSR, HIGH);
digitalWrite(LED, HIGH);
delayMicroseconds(50);
digitalWrite(PSSR, LOW);
digitalWrite(LED, LOW);
i = 0; // Reset the accumulator
zero_cross = 0; // Reset the zero_cross so it may be turned on again at the next zero_cross_detect
} else {
i++; // If the dimming value has not been reached, increment the counter
} // End dim check
} // End zero_cross check
}
void zero_cross_detect()
{
zero_cross = 1;
// set the boolean to true to tell our dimming function that a zero cross has occured
}
I’m sure I’m missing something but I was using the water sensor example code posted by peekay123 in the Flow sensor library thread.
