// Function description----------------------------------------

// Main function. Receives button selection from user.

// Turns on power to Communications MCU and forwards button selection.

// Waits for a signal indicating that data has been downloaded and written to SD

// card.

// Turns off WiFly, and gives power to Digital photo frame, also enables read.

// Times out, or starts again with another button press.

// Makes ready Read_enable for operation

// Sets timer period value

// Sets timer compare value

// Enables timer interrupts

// Reads input from user.
