ARDUINO SOURCE CODE
/*
* 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 (if daisy-chained, this goes to SIN of the next TLC)
* 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.
*
* 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 of TLC1 -> BLANK of TLC2 -> …
* The one exception is that each TLC needs it’s own resistor between pin 20 and GND.
