You need help to write a program that transmits a series of characters (in C).
The sequence will consist of "AlphaNumber", where Alpha is meant to be a letter, cycling from A to Z, and Number is a digit that cycles through 0 to 9. The sequence that comes out should look something like "A0B1C2D3....".
The objective is to send a letter-number pair every 500 milliseconds. We will also want to be able to restart the sequence, so we will watch for a capital R to be received and once it comes in, restart the sequence at "A0".
Program structure
SetUp:
Set serial port baud rate.
Set up Timer
Loop: if 500 milliseconds have passed
Send message
Update message
if serial data has come in
if serial data equal to 'R'
Reset message transmission.
The baud rate should be 9600 baud and the code should use the following functions: Serial.begin(baud), Serial.print(), Serial.available(), and Serial.read().
