The TLC5490 library (http://playground.arduino.cc/learning/TLC5940 ) should be modified to be working with Arduino Leonardo. The Solution can be found here:
http://forum.arduino.cc/index.php?topic=110394.0
I went through all the process and this solution works fine. This post is my documentation.

How to count time in Arduino
There are two simple ways to do pretty exact time counting in Arduino. The first one is to use delay(). Everytime it runs a delay(1), it's 1 millisecond passed. (1millisecond =0.001second, which means to delay 1 second you need to run delay(1000). ) Like this, you can count the runnning time by counting the delayed milliseconds.
But you may have many defferent delay() in your loop codes and you don't know how many milliseconds have been delayed anymore because it runs everytime differently. In this case you will need to use millis(). It's an internal clock in Arduino which starts to count time everytime the Arduino board starts running or is reseted. It can be counted to 50 days. To give the data of millis() to a variable you have to define this variable as unsigned long.
Code Example

unsigned long Val;
void setup(){
Serial.begin(9600);
}
void loop(){
Val = millis();
Serial.print("Count = "); Serial.println(Val);
delay(1000);
}
