Solve a next few tasks with a goal of getting started with mbed NXP LPC1768 platform:

1. Read the introduction to the mbed LPC1768 microcontroller. Check if the latest board firmware is installed. If not, update the firmware to the latest revision using these instructions. Start the Hello World program.

   Import program

   HelloWorld - main.cpp

   00001 #include "mbed.h"
   00002 
   00003 DigitalOut myled(LED1);
   00004 
   00005 int main() {
   00006     while(1) {
   00007         myled = 1;
   00008         wait(0.2);
   00009         myled = 0;
   00010         wait(0.2);
   00011     }
   00012 }
   

2. Examine the documentation for DigitalOut class. Turn any LED on/off using class DigitalOut member function write. Explain the role of operator= in the class documentation.
3. Modify the Hello World program to flash other 3 LEDs.
4. Modify the program to flash 2 or more LEDs at the same time (almost at the same time).
5. Modify the program to flash the LED1 for 4 seconds, then turn off LED1 and flash LED2 for 4 seconds, turn off LED2 and go back to flash LED1 for 4 seconds etc. Use the while and for loops for this task.
6. Declare and initialize two constant real variables T_TOTAL and T_FLASH, which will determine the total flash time of individual LEDs from the previous task, as well as the duration of each flash. E.g. instead of 4 seconds, set the total of 10 seconds for T_TOTAL and instead of default 0.2 seconds for T_FLASH, set the 0.5 seconds. The idea is to make a change only on those two places, and the rest of the code must carry out the task.
