Standard Interface for Light Programs

@billpugh I propose a standard interface for calling into light 'programs' on the Teensy. It should be standardized so that we can switch between programs easily.

I was imagining something like this:

void program_setup(RNLight *strip);
void program_loop(RNLight *strip);
void program_teardown(RNLight *strip);

Each program gets a chance to setup and loop like a normal .ino program. The program_teardown() is called when the program is about to be switched to another program and lets us cleanup any memory. program_setup() is called before the program is run, and program_loop() is called just like in a .ino.

An initialized RNLight is passed to each program so they do not need to initialize the strip each time we switch programs.

We should also decide on which clock frequency we will use for the Teensys since that will effect the timing of programs.

Would love to hear thoughts on this proposal, as well as whether it should be a C++ or C interface!

RNLights function to set color using uint32_t

The RNLights functions to set pixel colors all take 3 parameters (red,green,blue). I have a lot of code that already has the colors in a uint32_t with the blue value being the significant byte.

@billpugh Can you add a setPixelColor() function that looks like this?

void setPixelColor(uint16_t pixel, uint32_t color);

This is consistent with what Adafruit provides.

Load constants over EEPROM

What's up with setBrightness() ?

@billpugh I am seeing a lot of projects that use the setBrightness() function of the AdaFruit library. I have found versions of the library both with and without that function. Any idea what's up? Was it deprecated?

Gradient bug?

Shouldn't the following line:

https://github.com/billpugh/Pyramid-of-Possibilities/blob/master/Arduino/libraries/RNLights/RNGradient.cpp#L58

be

v2 = mix(position, s2, e2);

?

Evaluate sending report from interrupt handler

Latest commits break the LEDs

@billpugh I pulled you latest commits but the LEDs are no longer turning on. I am testing with the Beacon, FlashEcho and Qbert animations. When I jump back to an older commit (my last commit) then everything works fine. Thoughts on what may have changed? I can see serial logs on the monitor, so perhaps you changed the output pin of the LEDS or something like that.

Here are the console logs from FlashEcho

RNLightTest not compiling

Hey, I am getting a compiler issue with the RNLightTest. Let me know if anything comes to mind for fixing it easily.

Question about using an object as an animation parameter

@billpugh I just want to make sure that it is ok to use an RNGradient object as an animation parameter. I could imagine it going wrong, but if you're ok with it then I am too ;)

struct RadialParameters {
    uint8_t bpm = 25;    // beats per minute
    float thickness = 100;
    RNGradient gradientInside = RNGradient(0, RNGradientCapped, 0x000000, 0x000000); 
    RNGradient gradientShell = RNGradient(0, RNGradientCapped, 0xFF0000, 0xFF0000); 
    RNGradient gradientOutside = RNGradient(0, RNGradientCapped, 0x000000, 0x000000);   
};

Simulation0 compilation under linux

I am not sure whether the goal is to make it cross platform or not but I tried to compile MyOpenGLView.m under linux.

Prerequisite: install GNUstep

Here is the command line I used:

gcc MyOpenGLView.m -lGL -lGLU -lGLUT -std=c99 -lobjc -lgnustep-base -w -fconstant-string-class=NSConstantString

Also, I needed to add the following includes in the .h:

#include <GL/gl.h>
#include <GL/glu.h>

and replace OpenGL by GL in the .m

Then the main issue I am having is that I can't find a linux implementation of GLKit.
Here is my console output:

Update Adafruit_NeoPixel.h

@billpugh The new version of Adafruit_NeoPixel.h correctly includes:

#ifndef ADAFRUIT_NEOPIXEL_H
#define ADAFRUIT_NEOPIXEL_H

It also includes the setBrightness() function. Should we update to using their libraries now?
