2.7. Get scan data
Function Description:
Retrieve the scan data into the buffer. Return the length of characters. It also returns the barcode
type if type is not NULL. Return 0 means that the buffer is too short to hold the data. USI_GetData
should be called when SM_DATAREADY message is received. Or call USI_ResetData to discard
the data. Both of them will reset the data buffer so that next scan data can come in. If the data buffer
is not empty and a new scan data occurs, it will be discarded and an error message SM_ERROR
with code of SERR_DATALOST will be sent.
