int32_t bitStart, int32_t bitCount, uint32_t *state);
Required Header: stdmpi.h
Change History: Added in the 03.02.00
Description
mpiSqNodeSegmentDigitalIn gets the current state of multiple digital inputs on the specified slice on a SynqNet node.
| node | a handle to a SynqNet node object. |
|---|---|
| segment | the index of the slice/module attached to this SynqNet node. For more information, please see the Overview of MPI I/O. |
| bitStart | the first bit |
| bitCount | the number of bits to be read. |
| *state | a pointer to a int32_t word that will be filled in by this function. |
| Return Values | |
|---|---|
| MPIMessageOK | |
Sample Code
The following MPI code will get the current state of all the digital inputs (the following slice has 8 inputs) on segment 1 of node 0:
int32_t x;
mpiSqNodeSegmentDigitalIn( sqNode0, 1, 0, 8, &x );
