I have the problem that i need to send data and get data from and to functions in a dll. However i having problems with getting the data, not sure if is arrays or not, from the manual the two are descrided as below.
--------------------------------------------------------------------------------------------------------
short CVICDECL MSA_read_data(short mod_no, unsigned long from,
unsigned long to, unsigned long * buf, short add);
--------------------------------------------------------------------------------------------------------
Input parameters:
mod_no module number (0 - 3)
from 1st address to read (0 – POINTS_NO - 1)
to last address to read (from – POINTS_NO - 1)
*buf pointer to data buffer to be filled
add 1 – add read values to the buffer, 0 – rewrite buffer contents
Return value: 0 no errors, <0 error code (see msa_def.h)
And.
--------------------------------------------------------------------------------------------------------
short CVICDECL MSA_fill_memory(short mod_no, unsigned long from, unsigned long to, unsigned short fill_value);
--------------------------------------------------------------------------------------------------------
Input parameters:
mod_no module number (0 - 3)
from 1st address to fill (0 – POINTS_NO - 1)
to last address to fill ( from – POINTS_NO - 1)
fill value value written to the MSA memory
Return value: 0 no errors, <0 error code (see msa_def.h)
The procedure is used to fill a specified part of the memory of the MSA module ‘mod_no’ with the value ‘fill_value’.
However i´m not sure if the *buf should be a U32 pointer to an array or if the U16 fill value should be an array or a just a number?
my dll sofare is attached.
