Macros
Input macros (parameters set/get)
To be used in a switch() block.
#define	PARAM_CHAR(n, p)
	in case n, assign next byte in the message to p
#define	PARAM_INT(n, p)
	in case n, assign next 16 bit integer in the message to p
#define	PARAM_LONG(n, p)
	in case n, assign next 32 bit integer in the message to p
#define	GETPARAM(n, p, i)
	in case n, set i to the value of parameter p

Functions
Initialization
void	fraiseInit (void)
	Init fraise device stack. Normally automatically called by fruitInit(). More...
Service
void	fraiseService (void)
	Fraise device service routine. More...
Fraise output to master
char	fraiseSend (const unsigned char *buf, unsigned char len)
	Put a message into the Fraise TX queue. More...
Broadcast output
void	fraiseSendBroadcast (const unsigned char *buf, unsigned char len)
	Broadcast a message to every connected fruit; this fonction is blocking (it returns when the message is sent) More...
Input Functions prototypes
User may define any of these four functions, that are called when the device receives a message. Each input function is for a specific type of message. These functions then parse the received message using one of the Input Routines or Input Macros.
void	fraiseReceiveCharBroadcast ()
	String message to every device.
void	fraiseReceiveBroadcast ()
	Raw message to every device.
void	fraiseReceiveChar ()
	String message to this device.
void	fraiseReceive ()
	Raw message to this device.

Input routines
Use these functions when parsing the current message in Input Functions.
#define	fraiseGetInt()
	Get next 16 bit integer from receive buffer.
#define	fraiseGetLong()
	Get next 32 bit long integer from receive buffer.
unsigned char	fraiseGetChar ()
	Get next char from receive buffer.
unsigned char	fraisePeekChar ()
	See next char (but keep it in the buffer).
unsigned char	fraiseGetIndex ()
	Get read index in RXbuffer.
unsigned char	fraiseGetAt (unsigned char i)
	Get RXbuffer content at a given place.
unsigned char	fraiseGetLen ()
	Get total length of current receive packet.
void	fraiseSendCopy ()
	Copy the RX buffer to TX buffer, in char mode, from first RX byte to the one before current index (don't add last fraiseGetChar). Used to return queried parameter setting.
