Example(s):
As noted, the shutdown function really only disables the ISR’s, so you can still use the manual transmit and receive
functions if you wish.

Initialize UART to N81, 38400, manually transmit “Chameleon”, shut the UART down.
Assuming the Chameleon AVR is connected to a PC or other terminal with VT100 capabilities, print 10
Print out “Hello World!”.
Print the powers of 2 from 1 to 256.
connected to the Chameleon AVR, this function is a nice helper to print newlines when needed. Returns
nothing.
string, takes a pointer to the ASCIIZ string. Returns nothing.
UART_Newline() simply send a CR/LF (0x0A, 0x0D) to the UART. Assuming, a terminal program is
UART_Print_String(…) prints a NULL terminated string. The function first prints a newline then the
UART_Print_Int(…) takes a signed decimal integer and prints it to the UART. Returns nothing.
