Hi,
I am currently using Peter Mackeys code to drive a tlc5940. At the moment I have 32 LEDs that fade in and out sequentially.
http://pixelriot.com/pmatp/node/15
His code loops the following:
void loop () {
incrementFades();
setGreys();
feedPorts();
}
But I want to create an adjustable delay that I can put at any point along the run of the LED chase. For example Id like led's 0-18 to light up and fade out as normal, and then LED#19 wont start until 3 seconds later.
What Ive done is made an incrementFadesA() and incrementFadesB(), where A's loop goes from 0-17, and B's goes from 18-31.
Because the tlc5940 needs to be updated constantly, putting in a simple delay(300); wont work.
Ive been trying things like
void loop () {
setGreys();
feedPorts();
if(millis()<900){
incrementFadesA();
}
if (millis()>=1500) {
incrementFadesB();
}
}
but only incrementFadesA(); will work.
Is there an independent timer or sequence I can run that wont affect the setGreys() or feedPorts(), so that I can run incrementFadesB() at a later time?
thanks
