No outputs for `get_info.py` with BSC203 and NRT150 about pyapt HOT 5 OPEN

Can post the modified get_info.py to a gist or in a comment? Can you insert some print statements into Controller._read_message and see what the hardware is sending back?

from pyapt.

For above output of python get_info.py , I added some print lines in \pyAPT\controller.py to see what is happening. However, I have just put controller.py back as it is in the repository. Then I have added controller._read_message which did not show any output as seen below:

python get_info.py

#!/usr/bin/env python
"""
Usage: python get_info.py [<serial>]

Gets the controller information of all APT controllers, or the one specified
"""
from __future__ import absolute_import
from __future__ import print_function

import pyAPT

from runner import runner_serial

@runner_serial
def info(serial):
    print ('###  TESTING get_info.py  ####')
    print('serial=   ',serial) #70112214

    con=pyAPT.Controller(serial_number=serial)
    print('pyAPT.Controller(70112214) =   ', con)
    con._read_message()
    con.info()

if __name__ == '__main__':
  import sys
  sys.exit(info())

terminal output

the terminal output is the following and the script just get stuck there (i.e. not showing anything for con.read_message() and con.info()).

pyAPT.Controller(70112214) =    Controller(serial=70112214, device=<pylibftdi.device.Device object at 0x7ff0748fc5c0>)

Any suggestions?

@mxochicale I have pushed a new branch that has debugging output inserted. Can you please checkout branch issue-12 and re-run get_info.py

FYI I am no longer at Oxford and therefore do not have access to any Thorlabs hardware.

Thanks @freespace for your kind reply and your message on not having access to any Thorlabs hardware. I have updated my local repo and checkout issue-12 branch and apparently there is no response for the reading message header as shown below:

Do you have any suggestions?

By the way, I will come back to the lab on 13 of January 2020 to hopefully sort out this issue with your help.

@mxochicale it looks like the controller isn't responding to the APT commands. This could be due to a few things: a change in how APT is implemented; hardware fault; configuration issue; etc.

The first step would be to determine if it is at all possible to communicate with these controller using the APT protocol. Download the APT software from https://www.thorlabs.com/software_pages/ViewSoftwarePage.cfm?Code=Motion_Control&viewtab=1 and attempt to manipulate your stages and controllers. If this work then it rules out hardware and configuration issues.
