Important notes for Windows 10 | Issue | Fix | |-------|-----| | Driver not loading | Disable driver signature enforcement temporarily (not recommended) or use official CH340/CP210x drivers | | No DMX output | Some dongles need 5-12V power on DMX line (fixture provides it) | | Wrong baud rate | Lixada requires 250000 – verify in code | | Timing sensitive | The _send_break() method works on most Windows 10 PCs. If unstable, use QL+ or Freestyler instead | If you need a real Windows kernel driver (not a userspace script) or a signed .inf driver package , that is a much larger task requiring Microsoft certification and hardware testing. For 99% of users, the Python script + standard USB-serial driver is the correct solution.
