Functions
void	uart_init_circ_buf (tcirc_buf *cbuf)
	This will intialize the circular buffer head and tail of tcirc_buf struct.
void	uart_add_to_circ_buf (tcirc_buf *cbuf, uint8_t ch)
	This will add a new character to the circular buffer.
uint8_t	uart_get_from_circ_buf (tcirc_buf *cbuf)
	This will get a character from the buffer requested.
void	uart_clear_rx_buf (void)
	This will clear the RX buffer.
uint8_t	uart_circ_buf_has_char (tcirc_buf *cbuf)
	This will check for a character in the requested buffer.
uint8_t	uip_ntohex (uint8_t val)
	This will convert a nibble to a hex value.
void	itohex (uint8_t val, char *str)
	Convert integer to hex value.
uint8_t	uart_get_char_rx (void)
	This will wait for a new character from the ATmega1284p and timeout if no new character is received.
void	uart_init (void)
	Initialize UART to 38400 Baud Rate and only enable UART for transmission.
void	uart_deinit (void)
	Turn off UART for sleep mode.
void	uart_send_byte (uint8_t byte)
	Send one byte over the uart.
	ISR (USART_RX_vect)
	This is the USART RX complete interrupt.
void	uart_serial_send_frame (uint8_t cmd, uint8_t payload_length, uint8_t *payload)
	This function builds and sends a binary command frame to the ATmega1284p.
void	uart_timeout_msg (uint8_t x)
	This displays a time out message to the user based on the parameter reason x.
void	uart_serial_rcv_frame (uint8_t wait_for_ack)
	This will receive a frame from the ATmega1284p and parse the incoming data.
Variables
tcirc_buf	rxbuf
	The RX circular buffer, for storing characters from serial port.
