...single, reliable UART stream. The end goal is clear: squeeze the maximum possible throughput out of the link without sacrificing data integrity. The work revolves around three core competencies—TDM protocol development, raw ADC data handling, and low-level UART communication—so fluency in each of these areas is essential.

I want a small utility that runs on Windows and listens to my DualSense controller. The logic is simple: while L3 is held down, the script should read the X-axis of the left analog stick. When that value is negative it must fire the Circle input; when it is positive it must fire Square. No other checks or remapping are needed right now—just this one behaviour, kept as latency-free as possible. Please build the script, package any dependencies, and include a quick read-me so I can launch it, stop it, and tweak button codes later if I wish. A lightweight approach is ideal, but I’m open to your preferred language or library as long as the end result works reliably on Windows with a connected DualSense.

The core model must be YOLO, and I need the exact same code-base to compile and run on both Windows (desktop with NVIDIA GPU) and a Raspberry Pi 4. Video sources vary—some cameras stream RTSP over IP while a few older analog units reach the NVR through a capture card—so the program has to accept either type without manual re-configuration. For product recognition I care only about groceries; no clothing or electronics labelling is necessary. The model should be trained (or fine-tuned) on the most common supermarket items so false positives stay low even when shelves are crowded. Key expe...
