mpiMotorGeneralIn
Declaration
int32_t mpiMotorGeneralIn(MPIMotor motor,
int32_t startBit,
int32_t bitCount,
uint32_t *state);
Required Header: stdmpi.h
Change History: Added in 03.02.00. mpiMotorGeneralIn replaced mpiMotorIoGet.
Description
mpiMotorGeneralIn reads the current input state of one or more general purpose bits.
Each SynqNet drive has a different way of using general purposes I/O bits. To see how each FPGA is mapped to the general purpose I/O bits on a specific SynqNet drive, select the drive from the menu below. If the SynqNet drive you are using is not listed, refer to our SynqNet Drives page for more information.
NOTE: mpiMotorGeneralIn replaced mpiMotorIoGet in the MPI library.
| motor | a handle to the Motor object |
|---|---|
| startBit | the first general purpose bit that will be returned by the function. |
| bitCount | the number of general purpose bits that will be returned by the function. |
| *state | the address of the current state of the inputs that is returned. |
| Return Values | |
|---|---|
| MPIMessageOK | |
Sample Code
int32_t x;
mpiMotorGeneralIn( motor0, 0, 1, &x );
