Hi
could some kindle one let me know how I could run Marks Fire2012
from the opposite end of of the strip please.

tried changing the following
for( int= 0; i< NUM_LEDS: i++) {
to
for(int i=50; i>NUM_LEDS:i–){ //50 as I have 50 LEDs
this didn’t work.

2

Try… for(int i = NUM_LEDS 1, i=<0, i-)

3

ooops… reedit to… for ( int i = NUM_LEDS - 1 , i >= 0 , i - - )

4

Damn it… for ( int i = NUM_LEDS - 1 ; i >= 0 ; i - - )

Hi JP Roy
just tried it is still working from the same end.

There are more than just one place where you need to apply the same reversed loop

7

Did you see this in the code?
bool gReverseDirection = false;

sorry, no I have not seen that code. any example would be much appreciated

Check my Rings of Saturn code on Github (username: modustrialmaker). you’ll have to look through a bunch of functions, but it has a couple examples of Fire coming from both ends in it (searching for “fire” should locate them pretty quickly in the code).

@Chithru_Mihiripenna - as @marmil said: look at line 11 in:

and change false to true. This should change the direction of the fire on the strip to the other end.
