Detailed Description

This class controls a TLC5940 PWM driver IC.

Using the TLC5940 class to control an LED: 

  #include "mbed.h"
  #include "TLC5940.h"
  
  // Create the TLC5940 instance
  TLC5940 tlc(p7, p5, p21, p9, p10, p11, p12, 1);
  
  int main()
  {   
      // Enable the first LED
      tlc.set(0, 0xfff);
      
      while(1)
      {
      }
  }
