Develop a program for the PIC 16F84A using the MPLAB v8 IDE simulator software.

The program is to convert 10 ASCII characters one character at a time, to the excess-three code. Each converted character is to be displayed on 4 LEDs connected to Port B (B0 to B3) of the microcontroller.

Additionally, each converted character will be ON for 4 second and OFF for 1 second. Once all characters have been displayed the program will continue to run with all the LEDs flashing (ON for 1 second and OFF for 1 second then repeat this infinitely).

I don't know where to start, I need to

Describe your program using properly structured flowcharts (main program and subroutines).

Demonstrate the use of subroutines, e.g. initialize the peripheral registers and to set the time delays, etc.
