here's what I got.
ESP8266-12E (actually built by NodeMcu, but the pinout is same as the link) https:// acrobotic.com/acr-00018
LED strip uses WS2811 chip
The code I borrowed from works and partially works with the mods I made. I'll just post the sections I changed, but the complete code is here. https://github.com/jasoncoon/esp8266-fastled-webserver
What it does The original code connects to the wifi Uploads a control page when you point a separate browser to it's IP Changes the pattern/colors with your input
My changes The original program is setup for one long LED strip which I tested to verify everything worked. I then cut the strip into three sections for under cabinet lighting. I want them each on their own pin so I can control the delay between them (by making strips seem longer than they are).
The issue The problem is after cutting the strip and connecting, not all three strips light together. (to the best of my memory from last night) With all 3 in, only strip 1 works Unplug strip 3 causes 1 and 2 to work Unplug strip 2 causes 1 to work and 3 still doesn't work Unplug strip 1 causes 3 to work and 2 still doesn't work (I think it was that order) Each strip alone works in their respective pins Keep in mind the original setup with one long strip did work just fine.
Code changes (with a little on either side to help find it in the original code) This first section was modified to account for different strips with different lengths
// the very next line is original, but I commented out to add data pins later
//#define DATA_PIN 8 // for Huzzah: Pins w/o special function: #4, #5, #12, #13, #14; // #16 does not work :(
#define LED_TYPE WS2811
#define COLOR_ORDER BRG
#define STRIP_1 6 // seperate strips are numbered and added together to form one long chain
#define STRIP_2 67 // by adding extra leds, you add a delay so you don't jump a gap between strips too fast
#define STRIP_3 27
#define STRIP_12 STRIP_1 + STRIP_2
#define NUM_LEDS STRIP_1 + STRIP_2 + STRIP_3
#define MILLI_AMPS 10000 // IMPORTANT: set here the max milli-Amps of your power supply 5V 2A = 2000
#define FRAMES_PER_SECOND 120 // here you can control the speed. With the Access Point / Web Server the animations run a bit slower.
FastLED.addLeds was originally one line that is now 3.
FastLED.addLeds<LED_TYPE, 5, COLOR_ORDER>(leds, 0, STRIP_1); // for WS2812 (Neopixel)
FastLED.addLeds<LED_TYPE, 6, COLOR_ORDER>(leds, STRIP_1, STRIP_2);
FastLED.addLeds<LED_TYPE, 7, COLOR_ORDER>(leds, STRIP_12, STRIP_3);
The reason for cutting the LED strip is mounting locations. Strip_1 is between fridge and stove Strip_2 is between stove and sink Strip_3 is between sink and the wall
The reason for separating them out on the pins is that FastLED did not seem to have an easy way to update the patterns. With the current setup, I know it at least partially works without having to go through and modify the 8 or so patterns already in the program. With Strip_3 disconnected, strips 1 and 2 waved back and forth as one continuous strip. To add delay without changing the patterns, I just tell it that Strip_1 is longer. This gives the impression that a bead of light travels through the stove and sink unseen and is seen again on the next strip.
Here is the example I'm used for this setup. https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples Half way down, "One array, many strips"
Disclaimer: I'm a mechanical engineer that didn't pay attention in school when we did the little programming req'd (hindsight on that one sucks). Anyway, I spent the last week and a half going through C++ tutorials and examples to get this far. Writing is going to be bad, but at least I recognize what 1/2 of the program is doing now.
