Python wrapper for interfacing to IntrepidCS Hardware.

Description

Python wrapper for interfacing to IntrepidCS Hardware.

Installing

• pip install python_ics

Platform specific Installation notes

Windows

• Windows requires icsneo40.dll to be installed in the PATH. This can be obtained through vspy3 or our hardware installation kit found here: https://cdn.intrepidcs.net/updates/files/RP1210KitInstall.zip

Linux

• Linux builds use libicsneo and are built against manylinux using cibuildwheel.
• libicsneolegacy.so is bundled with the wheel and python_ics will automatically use it.

MacOS

• Mac builds use libicsneo and are built using cibuildwheel
• libicsneolegacy.dylib is bundled with the wheel and python_ics will automatically use it.

Basic usage

import ics

devices = ics.find_devices()
print(f"Found {len(devices)} devices...")
for device in devices:
    # Print, open, load default settings, close
    print(device)
    device.open()
    device.load_default_settings()
    device.close()

Building from source

• Building from source requires clang and clang-format to be present on the build machine.
• python_ics has submodules, please be sure to initial all submodules also.

PS > git clone [e-mail]:intrepidcs/python_ics.git

PS > cd python_ics

PS > git submodule update --init

PS > clang --version
clang version 11.1.0
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\LLVM\bin

PS > clang-format --version
clang-format version 11.1.0

PS > python -m pip install .

Debugging on Windows with Visual Studio Code

• Build and install python_ics for debug. When installing python choose the following:
  • Customize Installation -> Advanced Options
    • Check Download debugging symbols
    • Check Download debug binaries
• Build python with debug:
  • Install Visual Studio 2019 build tools(NOTE: As of 2/5/24, it looks like MSVC 2022 does not build correctly with setuptools and debug configurations). You should be able to build from source already.
  • Create virtual environment and activate it (powershell):
    • python -m venv .venv
    • .\.venv\Scripts\Activate.ps1
  • Install dependencies:
    • python -m pip install -r requirements.txt
  • Set DEBUG environment variable:
    • $env:DEBUG = "1"
  • Build the extension:
    • python_d setup.py build --debug install --force
    • OUTDATED:
      • Build in debug (-g flag):
        • python setup.py build -g
      • Install into our virtual environment:
        • python setup.py install --force
  • Inside visual studio code:
    • Open the root python_ics directory
      • code C:\Path\To\python_ics
    • Make sure the python extension is installed (ctrl+shift+x)
      • Python
      • Python Debugger
    • Select the python interpreter from our virtual environment (bottom right with a python file open in the editor).
    • Open and place a breakpoint in src/icsdebug.py
    • launch "Python: Debug icsdebug.py"
      • Note the PID that is outputted to terminal (Can also add os.getpid() to watch window)
    • Place a breakpoint inside the function you'd like to debug in methods.cpp
    • launch "Debugger Attach" (launch.json) and enter the pid when prompted.
    • enjoy!
