void convertStreamToNumbers	(	uint8_t *	stream,
		uint8_t	size
	)

Waiting for a field of the type from the internal address.

Parameters

[in]	stream	- byte stream from usb;
[in]	size	- size of the converted stream;

bool readFromPreBuffer

(

uint8_t *

data

)

Read data byte from preparser buffer.

Parameters

[in]

data

- pointer to memory for data byte;

Returns

true - there is data byte; false - preparser buffer is empty
