dSPACE DS1103 ERP I/O Driver : Implementing the Driver : Driver Interface Functions

Driver Interface Functions

The dSPACE driver interface functions are declared in the file stm_dspace.h. The driver includes three functions:

stm_dspace_init() - This function is called only once. It configures and initializes the signals defined in the ERP I/O mapping table. If mapping is invalid, a warning or an error message is generated (and sent to the dSPACE ControlDesk).
stm_dspace_driver() - This function is called whenever data is read from, or written to, an I/O port. Therefore, this function is called very often and affects overall efficiency.
stm_dspace_close() - This function should be called before closing the connection with the hardware.
