Using IDE to Upload to Attiny85

Using Arduino Programming Questions
1

Hello Arduino Forum,

Using IDE to Upload to Attiny85.
When, in the status bar down in right corner it says:
'ATtiny 25/45/85 [not connected]' and the Sketch > Upload Using Programmer
method is used the program uploads fine.
When, in the status bar down in right corner it says:
'ATtiny 25/45/85 on COM4' the IDE returns error:
Compilation error: no matching function for call to 'Adafruit_NeoPixel::show(int)'

Is there a way to fix this?

Thanks.

Allen Pitts

Hello xfpd and the Arduino forum,

Is there way of uploading ino file?
Could not find an upload file link.
So here is the sketch copied herewith below.

Thanks.

// NeoPixel Ring simple sketch (c) 2013 Shae Erisson
// Released under the GPLv3 license to match the rest of the
// Adafruit NeoPixel library

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
 #include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif

// Which pin on the Arduino is connected to the NeoPixels?
#define PIN        4 // On Trinket or Gemma, suggest changing this to 1

// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS 16 // Popular NeoPixel ring size

// When setting up the NeoPixel library, we tell it how many pixels,
// and which pin to use to send signals. Note that for older NeoPixel
// strips you might need to change the third parameter -- see the
// strandtest example for more information on possible values.

Your upload is exactly what the forum wants to see.

I am not familiar with this line... it seems out of place (or missing something)... which may make pixels.show() look like an out-of-place call. Do you have a link to this "NeoPixel Ring simple sketch"?

[edit] Put comment marks "//" in front of this line... it was part of the comment describing how to count pixel (base 16).

[edit] Also, whatever command needed the buried open brace near the 0-through-15 also left an extra close brace at the bottom of the sketch, which needs to be removed.
