Code for displaying things on the marquee in the RAS room
To change the text displayed, just open up a make uart screen and enter in your text. No backspaces, and Enter will send the text.
To change the default message, change the buffer in main.c and change buffer_index to one less than the message length.
To change the scroll speed, mess with the constant that multiplies the last parameter to CallEveryUS (in ShiftRunUS) towards the end of shifter.c.
