Data Structures
struct	tcirc_buf
	Circular buffer structure. More...
Defines
ASCII characters defined

#define	SOF_CHAR (0x01)
	Start-of-frame character.
#define	EOF_CHAR (0x04)
	End-of-frame character.
Functions
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.
uint8_t	uart_circ_buf_has_char (tcirc_buf *cbuf)
	This will check for a character in the requested buffer.
void	uart_clear_rx_buf (void)
	This will clear the RX buffer.
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_send_byte (uint8_t byte)
	Send one byte over the uart.
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_serial_rcv_frame (uint8_t wait_for_it)
	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.
