Have you included the library through the library interface or have you only inserted that code? If you havenât done the former, please do, since thatâs whatâs required to get it working. The libraries youâve included should be on the left pane of the IDE.
@marmageek, get rid of the ânewâ in the Adafruit_Neopixel constructor call on line 17. Also, look at line 11 where the pixel type is defined. It SHOULD read:
@marmageek, I used the included Neopixel example as a template. You cast the pixel type as âTYPEâ instead of PIXEL_TYPE. Look at the very first error in the list!
I do not understand what you are trying to say. I defined (not âcastâ) TYPE as WS2812B and I use TYPE in the constructor. The fact that the demo defines PIXEL_TYPE is irrelevant.
@marmageek, my brain is in park and Iâm misfiring on some cylinders! You are correct. Iâll have to test compile once I get home. Can you compile one of the supplied neopixel examples without errors?
Double-check your declarations. You use new to create/instantiate an object which can then be assigned to a pointer variable. But if you just declare an object of the classâs type directly, you donât use new. For example:
Adafruit_NeoPixel *strip1; // strip1 is a pointer, but not initialized yet
strip1 = new Adafruit_NeoPixel(PIXELS, PIN, TYPE);
// ...or... (notice: _not_ an explicit pointer declaration)
Adafruit_NeoPixel strip2 = Adafruit_NeoPixel(PIXELS, PIN, TYPE);
According to that one should do as follows:
Adafruit_NeoPixel *strip1 = new Adafruit_NeoPixel(PIXELS, PIN, TYPE);
Adafruit_NeoPixel strip2(PIXELS, PIN, TYPE);
âŚ
Adafruit_NeoPixel *strip3 = &strip2;
âŚ
strip1 is allocated off the stack.
strip2 is allocated out of code_segment
strip3 is stack pointer
I have a feeling though that my error lies elsewhere. I will post my entire code (current state) here in a bit.
I am still getting these errors: xmastree-01.cpp:3:16: error: âAdafruit_NeoPixelâ was not declared in this scope uint32_t wheel(Adafruit_NeoPixel *unit, uint8_t pos);
