To Write Programs That Open \System\Program - Agilent Technologies 1660C Series User Manual

To write programs that open \system\program

Using NFS, mount the logic analyzer's file system as the control user.
1
Refer to the chapter "Accessing the Logic Analyzer File System."
From within your controlling program, open the logic analyzer file
2
{NFS mount path}\system\program and send text strings to
the file using "write" or "output" commands.
In C, you can use the write or putstr functions to write text strings to the
\system\program file.
Your operating system may buffer the commands before sending them to the
logic analyzer. To prevent this, you may need to empty the buffer after each
command. In C, you can use the flush function to empty the buffer.
Queries
Responses to queries appear as text strings in the \system\program file.
To retrieve information from queries, create a text buffer, open the
\system\program file and read the contents of the file into the buffer. In
C, you can use read or getstr to read the contents of the file into the
buffer.
Whenever you send queries to the logic analyzer, you need to pause your
program for a short time to allow the system to process the query before you
attempt to read the response. A time equal to or slightly greater than the file
timeout is sufficient.
Resetting the File Pointer
Whenever you change from reading the \system\program file to writing
the \system\program file, or from writing to reading, you need to reset
the file pointer to the beginning of the file. In C, you can use the rewind
function to reset the pointer, or you can close the program file, then
immediately re-open it.
