I need production-ready PWM firmware for a three-level neutral-point-clamped inverter, built and tested in Simulink, then auto-generated to run on a TMS320F28379D. Reliability is my overriding concern: every carrier cycle must be generated without dropouts, jitter, or pulse misplacement. Precise timing control on the C2000 core is therefore mandatory, so the code has to make disciplined use of the F28379D time-base sub-modules, EPWM trip-zones, and DMA where appropriate. Here is how I picture the workflow and hand-off: • Start from a Simulink model that reproduces the inverter’s three-level space-vector modulation, including dead-time and level-shifting logic. • Configure Embedded Coder so the build flashes straight to the F28379D and can be inspected in Code Composer S...

I have the stock MED17.1 binary that runs on the Infineon Tricore TC1796 ( Audi A4 2011 ). My end-goal is simple: add a rolling anti-lag feature to the calibration, triggered only when the cruise-control button is pressed. Here is what I need done: • Disassemble the MED17.1 file in IDA Pro and label the key boost, torque and ignition routines so the logic is repeatable in future versions. • Craft a compact patch—either in Tricore assembly or C inserted via inline assembler—that implements rolling anti-lag. The code must: – Arm only when the cruise-control button bit goes high, – Stay engaged while the button is held and vehicle speed exceeds the set threshold (I will provide the hex address for that flag if needed), – Exit cleanly ...

I need a small, self-contained Python backend that ingests local MP3 files and automatically extracts musical information. For every track the service must detect • BPM and time signature • Overall tempo as well as integrated loudness (LUFS or a comparable metric) • Phrase boundaries and sections of complete silence Once a file is processed the results have to be written to a single CSV file—one row per track, neatly formatted with column headers for each metric. No database or JSON output is required. A minimal REST or command-line interface that lets me submit a path to an MP3 and returns the processing status is enough; the core value is the signal-processing code itself. Please rely on well-known Python libraries such as librosa, Essentia, pydub or simil...

I need a compact laser-based device that can track a golf ball in real time, capture its rolling speed frame-by-frame, calculate deceleration, and then switch seamlessly to measure vertical bounce height as well as the ball’s speed just before and after impact with the ground. Rolling speed data is the top priority, yet the bounce metrics are still essential to the overall solution. Because I’ll be moving the unit between an outdoor green and an indoor practice mat, the optics and housing must cope with varying light levels, surface colours, and the occasional speck of sand or moisture. I expect millisecond-level timestamping on all speed and deceleration outputs, delivered either through an onboard display or a simple USB/BLE data stream that I can log to a laptop. Pleas...

I already have the full schematic and the finished PCB files for a board that combines an ESP module with a PIC18F microcontroller. What I’m missing is a clear, practical explanation of how everything talks to each other, especially over UART, and how that interaction is implemented on the physical board. Here is what I need from you: • A step-by-step walkthrough of the signal paths that handle UART traffic between the ESP and the PIC18F, including any level-shifting, buffering, or hand-shake lines that support the link. • A guided tour of the PCB layout that shows where those signals travel—layer changes, vias, ground references, decoupling, and any routing choices that affect integrity or noise. • Simple notes on any supporting circuitry (power rails, ...

I need a focused research effort that looks at satellite-communication antennas from three angles at once: maximising signal strength and quality, mapping frequency-band usage, and refining antenna design and materials. The outcome should give me clear, data-backed guidance I can hand straight to my hardware team. Scope You will survey current literature and patents, run electromagnetic simulations (HFSS, CST, FEKO or similar), and translate the findings into practical design recommendations. Emphasis is on L-, S- or Ku-band performance; however, if your analysis uncovers a better-suited band, flag it and justify the choice. Deliverables • Concise comparative report (PDF) • Simulation files with setup notes • Performance charts showing gain, VSWR, efficiency and li...

OVERVIEW The United Nations Development Programme (UNDP), the Seeker for this Innocentive Challenge, is searching for creative, affordable solutions that can safely detect and mark the presence of underwater explosive ordnance. In conflict or post-conflict zones, vast quantities of explosive ordnance (EO) lie submerged in oceans, lakes, rivers, and coastal waters. From post-WWII dumping to modern conflict spillover, these extremely hazardous explosives jeopardize the lives, livelihoods, and environments of nearby communities. UNDP is particularly interested in solutions that can be safely used by members of these communities, empowering them and enabling widespread knowledge of these dangers without requiring military or high-cost commercial interventions. The ideal solution will allow ...
