Public Member Functions
	oEB500 (IOLINE imode, PORT ip, IOLINE iconnect, PORT pconnect)
	Constructor for eb500 Bluetooth module.
void	send_command (const char *const icommand, bool cr)
	transmits an ASCII eb500 command.
void	mode (EB500_MODE)
	Switches to COMMAND_MODE or DATA_MODE when using a dedicated channel for the mode.
void	receive_ack (void)
	will wait for a '>' character from eb500 module.
bool	connected (void)
	returns whether eb500 has a bluetooth connection using the dedicated channel.
void	init (IOLINE channel, UART_MODE mode, int dsize, PARITY_TYPE parity, int BAUD_RATE)
	Init specifying channel on TPU port, mode of transmission, parity, and baud rate.
void	priority (PRIORITY p)
	Sets TPU priority. Ref TPU Channel Utilization) PRIORITY: Priority of channel.
bool	havebyte ()
	Returns true if a byte was received; bool: Return true if data in internal buffer; otherwise false.
word	inbyte (void)
	returns the last unreturned data word
void	outbyte (word txbyte)
	puts character out.
int	sendingbyte (void)
	Whether module is still sending a byte or not.
int	send (const char *const buf, int nbytes)
	Write a string of characters.
void	buffer (volatile word *inbuffer, uint16 ilen)
	Provide a working buffer for the UART channel.
bool	active (uint8 r=FALSE)
	Used to determine stale information.
void	dump (void)
	Reset receiving counter after syncronizing messages.
uint16	byte_count (void)
	Returns number of bytes in signal buffer.
void	baud_rate (int dsize, PARITY_TYPE parity, int BAUD_RATE)
	Allows reconfiguring of baud rate...basically reinitiales the channel.
Static Public Member Functions
int	TCR1 (void)
void	TMCR (int iarb)
bool	HSQR (int chan, int val)
	Configures the host sequence register.
bool	HSRR (int chan, int val)

int	CISR (int chan)
	Returns the channel interrupt status register.
void	CISR_clear (int chan)
	Clears the channel interrupt status register for the channel.
bool	TICR (int cirl, int cibv)
	Configures the TPU interrupt configuration register.
int	tpu_vector (IOLINE channel)
	Given a channel, returns the vector number to use for an interrupt.

Member Function Documentation

bool CIER (  int  chan, int  cie )  [static, inherited]

Configures the channel interrupt enable register. Parameters: int:  channel int:  1 enables; 0 disables

bool CPR (  int  chan, int  val )  [static, inherited]

Configures the channel priority register (Ref. TPU Channel Utilization). Parameters: int:  channel int:  priority

bool havebyte (   )  [inherited]

Returns true if a byte was received; bool: Return true if data in internal buffer; otherwise false.

bool HSQR (  int  chan, int  val )  [static, inherited]

Configures the host sequence register. Parameters: int:  channel int  dependent upon function (CFSR) selected

bool HSRR (  int  chan, int  val )  [static, inherited]

Configures the host sequence request register. Parameters: int:  channel int:  dependend upon function

void send_command (  const char *const  icommand, bool  cr )

transmits an ASCII eb500 command. Parameters: icommand  : eb500 command to transmit cr  : true to append a carriage return to command.

int TCR1 (  void   )  [static, inherited]

misnomer--should be TCR1 divisor--return number of clocks (PSCK,TCR1P modifications) Globally available object. Can be used in combination with TPU_REGISTER definition to say TPU_REGISTER->CFSR.BITS...

void TMCR (  int  iarb  )  [static, inherited]

was tpu_init Configures the channel function select register
