Q2. Write the code so that the mbed counts up and displays the number as 4-bit binary on the four on- board LEDs. At the same time, the mbed sends these numbers through the serial USB cable to be displayed on the terminal of the pc, one on each line as shown below. Whenever the counter reaches its full count or user hits the 0-key, the mbed restarts counting from zero. Note >> the getc() function waits for user input. Therefore, it would be better to check first if the terminal is sending some data and this can be done with readable () function. If you hit a key, then readable()-1, otherwise readable ()-0 This can be accomplished with: if (pc. readable()-1) c=pc.getc ( ); // pc is a serial object ?COM35 .
