How exactly LCDOUT statement works?

[richard]

adding something useful like NEOPIXEL $ADDR,$BRIGHTNESS,$R,$G,$B

all of my posted examples can do that easily, except for brightness as its a function of r g b so would be a totally useless input

a neopixel usercommand could be added with a few more lines of code to make the process more explicit
but its trivially easy as is.
very few have shown any interest in this code , very few have even asked a question.

large arrays of neopixels can be resource hungry and will need a midrange chip. a general purpose version is and will
remain a fantasy, the hardware must match the job

tell me about it... That is why I prefer APA101.

So every job needs its tool. Cannot one size fit all.

But arduino does neopixel with ancient chip with ease?
and also supports brightness? (it is also supported with RGB, you know?)

The libraries and our own addons are of course great, but I'm speaking about centralized support - you just type in, it just works. No forum searching and guesswork.

As far as I know (correct me if I'm wrong) Arduinos support for NeoPixels is not part of the Arduino language itself. It's an add-in library that you have to download, install and include into your code in order to use it. It's not written or maintained by "Arduino the company" but by some third party (user, company, community) and I'm pretty sure there's more than ONE version of that library to choose from as well. Which can be confusing.

The same thing goes for a lot of other stuff that "Arduino has" - it's libraries written by users and rest assured that the quality of them varies. Pretty much the same thing as "our" stuff.

The big advantage is the encapsulation that proper function calls with parameter passing, local variables and return values provides. This provides the means to "hide away" even more stuff from the user than with PBP that doesn't support function calls and/or local variables. It's not magic though.

A month or so ago I posted code for driving SK6812 RGBW LEDs. Using that particular code your example

NEOPIXEL $ADDR,$BRIGHTNESS,$R,$G,$B

Would look like:

Red[ADDR]=R : Green[ADDR]=G : Blue[ADDR]=B : GOSUB UpdateDisplay

And if you wanted you could rename the UpdateDisplay subroutine to NEOPIXEL and it would be

Red[ADDR]=R : Green[ADDR]=G : Blue[ADDR]=B : GOSUB NEOPIXEL

Not THAT much different now, is it? Granted, the "library" IS hardcoded to run at 64MHz so you won't run a 16x16pixel array on a 12F508 - for multiple reasons.

You still need to include the code and set up some variables and aliases, but you don't get away from that with Arduino either.

[CuriousOne]

Regarding this particular library, it is supported and maintained by adafruit - major arduino contributor.
To use it in your project, you just go to library manager, type in neopixel there, click download & install and that's all.
all "define"s for it are here:

#define LED_PIN 14
#define NR_OF_PIXELS 12
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}

And to use it:

strip.setBrightness(255);
strip.setPixelColor(1,10,30,40);

no "hard coding" no "tied to 64mhz oscillator" - it just runs.
I understand that from approach of older guys like myself
this might appear to be not serious, but it allows you to get
to the end result faster - you need neopixel led, you got it
no need to care about osc clocks, tight timing and which
chip can do it, and which - can't.

Of course, arduino has it's own limitations - huge board with external osc
you can't run it off tiny SOIC-8 chip, as you can do with PBP
and that dreadful programming language, not meant to be understood by normal human beings

How does these chips compare to the many flavors of PIC's?

You can't have it all. Too many chips, too many specs, and all do the same thing. Not possible. You have to compromise and select a powerful chip, stick on this no matter how much it costs and do your light or heavy job. Close to what a powerful ATMEL chip does on Arduino. From flashing a LED to NEOPIXEL or more.

[CuriousOne]

Yeah but LCDOUT and other "specific" statements like OWIN do work on both low end beauties and high end PICs too?

[Ioannis]

Sure they do. They are low on resources need!

But Neopixel? no...

the typical micro in uno etc is ATmega328P thats slightly more 'powerful' than a 18f26k22
its no pic16 clunker, the arduino chips go upwards from there in performance

no "hard coding" no "tied to 64mhz oscillator" - it just runs.

that you can see , its there , tied into a mandatory small set of fixed hardware configurations
