Mega, TFT, RTC, and WS2815 query

ROBCC03 · June 11, 2020, 11:18am

Hi

Although i have been messing around with Arduinos for a while, i still have lots to learn, but as only a small hobby its hard to get time!

anyway, code is below, what i want, is a touch tft with controls over a 5 metre strip of leds which are outside up the length of our drive, which are triggered automatically when some breaks a IR beam (already in place for my old system).
this then triggers the leds to come on in sequence from sensor end up to the door (leading the way kind of) staying on for 10 seconds and then turning off from sensor to door..

but to complicate things again, i want to have control on the colour from inside. and also have a "temp" options to put the lights via toggle button on tft. And also an "exit" option which puts the lights on from door to sensor etc...

this is where im struggling. witht he delays and colour options to be stored and then called when needed...

the code has been played with over the last few days and isnt the prettiest im sure..

Bit more on my problem.

i want to be able to call up a standard strip of ws2815 LED's, on in sequence (either way from end to end) with a small delay between each on coming on, one for about 7-10 seconds, then off in the same direction at a different speed.

BUT, AND THIS IS WHERE I AM STRUGGLING, the colour needs to preset and stored somehow, ready for when its triggered (by the beam sensor) then they come on and then go off. But it remembers the colours for next time..

and then i press the touch screen for a different colour it will use that colour next next (this also puts a small box on the very bottom of the display to visually show me what colour is selected...

Full code is in previous post.. (deleted the part for diaplay date and time on TFT so code would be small enough to post in full

Trouble lies in storing colour info in "COL"

can anyone please help in storing the colour info so it can be called up.

something to replace "::Black;" with a variable

leds = CRGB::Black;

FastLED.show();*

OK, spent over a week on this problem. but i will keep trying things, even if no one helps me :o(
