Hi folks, I have a number of different LED (neopixel ws2812/ sk8618) types running on different nodes (ESP8266), and I want to load their config details from a txt file stored in the file system of each node. I have it working for unit ID and number of LEDs, and now I want to add the LED type eg NEO_GRB etc. Which looks like a string, but obviously isn’t; the Adafruit_Neopixel.h file defines then as eg
#define NEO_RBG ((0<<6) | (0<<4) | (2<<2) | (1)) ///< Transmit as R,B,G #define NEO_GRB ((1<<6) | (1<<4) | (0<<2) | (2)) ///< Transmit as G,R,B
so I guess they are ints, and have this typedef:
typedef uint8_t neoPixelType; ///< 3rd arg to Adafruit_NeoPixel constructor
so uint8_t. But I can’t call NEO_RGB.toInt(), or whatever, obviously…
I need ultimately to call
on my Adafruit_Neopixel object.
I am sure I just have to look at this issue in a different way and it will be clear, but can anyone help me see that different way?
This is running on ESP8266. My code so far:
File file = LittleFS.open("id.txt", "r"); String line; line = file.readStringUntil('\n'); //id number gID = line.toInt(); Serial.printf("gID = %d\n",gID); line = file.readStringUntil('\n'); //num leds gNumLeds = line.toInt(); Serial.printf("gNumLeds = %d\n",gNumLeds);
Thanks in advance,
