/*
|
||||
* First Attempt at generating the TLC output code from an image.
|
||||
* Run this with "java AnimationCreator"
|
||||
* It will read any image file in the current directory and create an animation for the TLC library.
|
||||
*
|
||||
* Right now this only works with 1 TLC with 16 LEDS connected to it, where
|
||||
* output0 is the bottom and output15 is the top.
|
||||
*
|
||||
* For best results make your files 16 pixels high and as wide as you want. Each vertical pixel
|
||||
* corresponds to an LED output.

Basic Pin setup:
|
||||
------------ ---u----
|
||||
ARDUINO 13|-> SCLK (pin 25) OUT1 |1 28| OUT channel 0
|
||||
12| OUT2 |2 27|-> GND (VPRG)
|
||||
11|-> SIN (pin 26) OUT3 |3 26|-> SIN (pin 11)
|
||||
10|-> BLANK (pin 23) OUT4 |4 25|-> SCLK (pin 13)
|
||||
9|-> XLAT (pin 24) . |5 24|-> XLAT (pin 9)
|
||||
8| . |6 23|-> BLANK (pin 10)
|
||||
7| . |7 22|-> GND
|
||||
6| . |8 21|-> VCC (+5V)
|
||||
5| . |9 20|-> 2K Resistor -> GND
|
||||
4| . |10 19|-> +5V (DCPRG)
|
||||
3|-> GSCLK (pin 18) . |11 18|-> GSCLK (pin 3)
|
||||
2| . |12 17|-> SOUT
|
||||
1| . |13 16|-> XERR
|
||||
0| OUT14|14 15| OUT channel 15
|
||||
------------ --------
|
||||
|
||||
- Put the longer leg (anode) of the LEDs in the +5V and the shorter leg
|
||||
(cathode) in OUT(0-15).
|
||||
- +5V from Arduino -> TLC pin 21 and 19 (VCC and DCPRG)
|
||||
- GND from Arduino -> TLC pin 22 and 27 (GND and VPRG)
|
||||
- digital 3 -> TLC pin 18 (GSCLK)
|
||||
- digital 9 -> TLC pin 24 (XLAT)
|
||||
- digital 10 -> TLC pin 23 (BLANK)
|
||||
- digital 11 -> TLC pin 26 (SIN)
|
||||
- digital 13 -> TLC pin 25 (SCLK)
|
||||
- The 2K resistor between TLC pin 20 and GND will let ~20mA through each
|
||||
LED. To be precise, it's I = 39.06 / R (in ohms). This doesn't depend
|
||||
on the LED driving voltage.
|
||||
- (Optional): put a pull-up resistor (~10k) between +5V and BLANK so that
|
||||
all the LEDs will turn off when the Arduino is reset.
|
||||
|
||||
If you are daisy-chaining more than one TLC, connect the SOUT of the first
|
||||
TLC to the SIN of the next. All the other pins should just be connected
|
||||
together:
|
||||
BLANK on Arduino -> BLANK of TLC1 -> BLANK of TLC2 -> ...
|
||||
XLAT on Arduino -> XLAT of TLC1 -> XLAT of TLC2 -> ...
|
||||
The one exception is that each TLC needs it's own resistor between pin 20
|
||||
and GND.
|
||||
|
||||
This library uses the PWM output ability of digital pins 3, 9, 10, and 11.
|
||||
Do not use analogWrite(...) on these pins.
|
||||
|
||||
This sketch does the Knight Rider strobe across a line of LEDs.

A circular light buffer. If you manage to construct a circle of LEDs,

definitely send in pictures. What this sketch does is take an analog

reading off of analog pin 0 and add it to the current value of the last LED.

If the resultant sum is greater than 4095, it turns the LED off,

otherwise sets LED 0 to the value of the sum.

If you ground pin 12, it will set LED 0 to zero.

Then it shifts all the LED values up one (so LED 0 becomes LED 1) and sets

LED 0 to the value shifted off the last LED (so if one LED is on, it will

go in a circle forever).
