“Microstar Laboratories, Inc., maker of Data Acquisition
Processor boards, today announced a new Linux driver for PCI DAP
boards to complement its existing Linux driver for ISA DAP
boards”
“The new driver works with all PCI DAP boards: from the
top-of-the-line DAP 5200a/526 to the entry-level DAP 840/103. The
existing Linux driver works with all ISA DAP boards in current
production: from the DAP 3400a/445 to the DAP 820/103. (For full
lists, visit the company Web site, www.mstarlabs.com.) Every DAP
model has onboard intelligence implemented as DAPL, a multitasking
real-time operating system that runs on an onboard processor; the
user controls this from an application running under a Linux system
that contains the board.”
“The new driver supports Linux kernel 2.2. An application
communicates with DAPL through the standard file system interface,
by using the C file system library functions, for example: open(),
close(), read(), write() and ioctl(). Any language that supports
Linux and its file system interface can communicate with the driver
through the file system calls. As with the existing driver,
Microstar Laboratories also provides C code for a limited set of
useful DAPIO functions that compile with and link to C/C++
applications. These functions effectively act as wrappers for the
standard file system functions.”
