🛠️ Refactor suggestion
Avoid bare except and ensure the serial port is properly closed.
- Replace the bare
exceptwith a more specific exception (e.g.,except serial.SerialException:). - Consider ensuring the serial port is properly closed, for example by using a
with serial.Serial(...) as ser:construct so that exceptions don’t leave the port left open.
Below is a sample diff showcasing more specific exception handling and a context manager for closing the serial connection:
-def is_mark_1():
- if is_wm8960():
- try:
- ser = serial.Serial("/dev/serial0", 9600, timeout=3)
- ser.write(b'system.version')
- while True:
- is_mk1 = ser.readline().decode().rstrip()
- if is_mk1 and "Command" in is_mk1:
- # This is a Mark 1
- return True
- break
- return False
- except:
- return False

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 Codebase verification
Requirements file path mismatch will cause installation failure
The requirements.txt file exists in the root directory, but setup.py is looking for it at requirements/requirements.txt. This mismatch will cause the installation to fail. Either:
- Move the file to
requirements/requirements.txt, or - Update
setup.pyto userequirements.txtinstead ofrequirements/requirements.txt
🔗 Analysis chain
Confirm that requirements/requirements.txt is available.
Be sure that the file requirements/requirements.txt is present and correct in the repository structure before installing. Otherwise, this call could lead to an error if the file is missing.
Below is a script to check if the file is present in the repo:
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Ensure the requirements file is in place.
fd 'requirements.txt'
Length of output: 38
Script:
#!/bin/bash
# Check for requirements.txt in the requirements directory and verify if root file is a symlink
fd -t f 'requirements.txt' -d 2
ls -la requirements.txt
Length of output: 137
Adds support for a Mark 1 device.
This does not setup the sound, just verifies that a Mark 1 is present.
