problem with the file "WS2812FX.h

[papybricol]

Hello, I try to use your Library, but with Arduino 1.6.13, and with Arduino : 1.6.5 (Windows 10), Carte : "Arduino Uno". IDE arduino replies in compilation: "In file included from test-effets-neopixels-fx.ino:3:0: C:\Users\jean-louis\Documents\1-ROBOTIQUE...techno\1-ARDUINO\2-DOSSIER des sketchs\libraries\WS2812FX/WS2812FX.h:123:37: error: 'neoPixelType' has not been declared WS2812FX(uint16_t n, uint8_t p, neoPixelType t) : Adafruit_NeoPixel(n, p, t) { ^ Erreur lors de la compilation."

Perhaps, it is in this line of file " .........h" ?? class WS2812FX : public Adafruit_NeoPixel { typedef void (WS2812FX::*mode_ptr)(void); public: WS2812FX(uint16_t n, uint8_t p, neoPixelType t) : Adafruit_NeoPixel(n, p, t) {

thanks for your help (Excuse my english language, it's very bad!) papybricol

Do you have the latest NeoPixel library installed? Can you post your code?

The files of the NeoPixel library was dated of 03/07/2014. To morrow, i will download the latest version.

I tried with the exemple "serial control" and this other program, the messages are the same for the 2.

`#include //error if absent

include

define LED_COUNT 16

define LED_PIN 8

WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

unsigned long previousMillis = 0; const long interval = 10000;

int effet = -1;

void setup() { ws2812fx.init(); ws2812fx.setBrightness(25); ws2812fx.setSpeed(200); ws2812fx.setColor(255, 255, 0); ws2812fx.setMode(FX_MODE_CHASE_RAINBOW); ws2812fx.start(); Serial.begin(115200); }

void loop() { ws2812fx.service();

unsigned long currentMillis = millis(); if (currentMillis - previousMillis >= interval) { ws2812fx.stop(); effet++; if(effet >= MODE_COUNT) effet = 0; Serial.println(ws2812fx.getModeName(effet)); ws2812fx.setMode(effet); ws2812fx.start(); previousMillis = currentMillis; } }`

I found some hints 03/07/2014 might be to old while googleing the error message.

Not related to the issue: You don't have to call ws2812fx.stop() before you change the effect. You might want to try: if (currentMillis - previousMillis >= interval) { ws2812fx.setMode((ws2812fx.getMode() + 1) % ws2812fx.setModeCount()); Serial.println(ws2812fx.getModeName(ws2812fx.getMode())); previousMillis = currentMillis; }

YES!!! It is OK (compilation) with the latest version 1.0.6 .of the neoPixel Library ( with Arduino IDE 1.6.5) But it is necessary to add the command #include <Adafruit_NeoPixel.h> in the 2 programs.

GREAT THANKS !

Tomorrow i will test with IDE 1.6.13 and connect the leds

Hello, With IDE 1.6.13, everything is Ok (for compilation) No need to add #include <Adafruit_NeoPixel.h>

Have a good day

Thanks for letting me/us know. Code/Arduino seems to be quite picky on versions.
