Section 7: TSP command reference
fs.is_dir()
This function tests whether or not the specified path refers to a directory.
Type TSP-Link accessible
Function Yes
Usage
status = fs.is_dir("path")
status
path
Details
The file system path may be absolute or relative to the current working system path.
Example 1
print("Is directory: ", fs.is_dir("/usb1/"))
Because /usb1/ is always the root directory of an inserted flash drive, you can use this command to verify that
USB flash drive is inserted.
Example 2
if fs.is_dir("/usb1/temp") == false then
fs.mkdir("/usb1/temp")
end
Insert a USB flash drive into the front panel of the instrument.
Check to see if the temp directory exists.
If it does not exist, create a directory named temp.
