Detailed Description

TI's TLC5940 interface class.

Example: 

 // Turn on all the outputs
 # include "mbed.h"
 # include "tlc5940.h"
 
 int main() {
     int DC_data[2*96];
     int GS_data[2*16];

     // Dot Correction Values
     for (int i=0; i<2*96; i++) DC_data[i] = 1;
     // Grayscale Values
     for (int i=0; i<2*16; i++) GS_data[i] = 0xFF;

     // Create object
     tlc5940 tlc_driver(2, DC_data);
     // Send data
     tlc_driver.send_data(GS_data);

     while (1) {}
 }
