Граф вызова функции:

char rfcc::receivePacket	(	char *	rxBuffer,
		char *	length
	)

Receives a packet of variable length (first byte in the packet must be the length byte). The packet length should not exceed the RXFIFO size. To use this function, APPEND_STATUS in the PKTCTRL1 register must be enabled. It is assumed that the function is called after it is known that a packet has been received; for example, in response to GDO0 going low when it is configured to output packet reception status.

The RXBYTES register is first read to ensure there are bytes in the FIFO. This is done because the GDO signal will go high even if the FIFO is flushed due to address filtering, CRC filtering, or packet length filtering.

Аргументы:

	*rxBuffer	Pointer to the buffer where the incoming data should be stored
	*length	Pointer to a variable containing the size of the buffer where the incoming data should be stored. After this function returns, that variable holds the packet length.

Возвращает:

0x80: CRC OK
0x00: CRC NOT OK (or no pkt was put in the RXFIFO due to filtering)

Граф вызовов:

void rfcc::sendPacket	(	char *	txBuffer,
		char	size
	)

This function transmits a packet with length up to 63 bytes. To use this function, GD00 must be configured to be asserted when sync word is sent and de-asserted at the end of the packet, which is accomplished by setting the IOCFG0 register to 0x06, per the CCxxxx datasheet. GDO0 goes high at packet start and returns low when complete. The function polls GDO0 to ensure packet completion before returning.

Аргументы:

	*txBuffer	Pointer to a buffer containing the data to be transmitted
	size	The size of the txBuffer
