2.7. Get scan data
Function Description:
Retrieves the scan data into the buffer. Returns 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.
Function call:
UINT USI_GetData(LPBYTE buffer, UINT len, UINT* type);
Parameter: (input)
len : UINT : Len specifies the maximum length of the buffer.
Parameter: (output)
buffer : LPBYTE : Data buffer for storing scanned data
type : UINT : barcode type which is defined on
USI.H. Please refer to below list
