Included on the SeaI/O CD are driver functions for use in accessing the I/O as well as helpful samples and utilities. Programming for Windows The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL). The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under “Application Programmers Interface”. This help file also includes detailed information dealing with installation / removal of the software and information about latency, logic states, and device configuration. For C language programmers we recommend using the API to access the PIO-96.PCI. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised. Samples and Utilities A variety of sample programs and utilities (both executable and source code) are included with SeaI/O. Further documentation on these samples can be found by selecting “Start/Programs/SeaIO/Sample Application Description”. Information about where the files are physically stored on your disk is also included in this same file. Programming for Linux SeaI/O for Linux consists of two major parts: a kernel module and a library. The kernel module is a simple IO pass-through device, allowing the library to handle the more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’ format and can easily be compiled and included in the kernel build. Direct Hardware Control In systems where the users program has direct access to the hardware (DOS) the tables that follow give the mapping and functions that the PIO-96.PCI provides. Reading the Inputs The inputs are active true. If an input is driven high (2V to 5.25 V) it will read as a logical one, if driven low (0V to 0.8V) it will read as a logical zero. If an input is not driven it will read as a one due to the 10K ohm pull up resistors on each port. Reading the Outputs The value that is currently being used to drive the outputs will be returned. © Sealevel Systems, Inc. - 12 - PIO-96.PCI User Manual Presetting an Output Port Each port has an output register associated with it. This register may be written and retains its value whether the port is configured as an input or an output. To preset the value of an output port the program should write to the port when it is configured as an input then configure it as an output. Writing the Outputs The outputs are active true. Writing a one (1) corresponds to 5V while writing a zero (0) corresponds to 0V, at the output.
