Samsung harddisk firmware jobs
I already use a small AI-driven automation suite to make console play more accessible for disabled gamers, but the Cronus Zen GPC at the heart of it still targets last-gen firmware. I need that script rebuilt so it loads and performs flawlessly on a PS5. The core brief is simple: keep everything the tool currently does, yet raise the aim-assist profile on Sony’s latest console. In practical terms that means: • Sharper target locking when acquiring enemies • Smoother recoil control so the reticle stays centred without sudden jumps You can code the logic however you like—inline combos, timing tables, or sub-routines—as long as it remains a single GPC file that flashes cleanly through Zen Studio. Comment your changes clearly so I can trace what was al...
... This is a pure troubleshooting engagement—no fresh installs or routine maintenance—so I’m expecting systematic diagnostics, clear root-cause identification and a fix that holds. The issue: noticeable performance degradation that shows up as slow internet speed for all users. Basic resets and router reboots have not helped, so I suspect something deeper (mis-configured switch, bandwidth hog, firmware bug, or similar). Here’s what I need from you: • Remote or on-site diagnostics using your preferred tools (Wireshark, NetFlow analyzers, SNMP monitoring, etc.) • Actionable remediation—configuration tweaks, hardware recommendations, or software updates—implemented and tested while you’re on the call. • A brief hand-over r...

I need a seasoned engineer who can take a concept for a smart electronic control system and turn it into production-ready hardware and firmware. The work spans the entire stack: schematic capture, mixed-signal PCB layout, component selection and BOM creation, followed by firmware in C/C++ for MCUs such as STM32, ESP32, AVR, PIC or similar. On the hardware side you should be comfortable sizing MOSFET or relay drivers, building ADC/DAC front ends, integrating industrial sensors, designing power-management and battery-charging circuits, and preparing complete manufacturing files (Gerber, pick-and-place, assembly drawings). On the firmware side I’ll rely on you for robust real-time control that makes full use of timers, PWM, interrupts, DMA and serial interface...

I need production-ready firmware for a small, battery-powered board built around the STM32G031G8U6 (ARM Cortex-M0+, 64 KB flash). The device’s job is straightforward sensor monitoring: it reads two TI TMAG5170 Hall sensors, drives three on-board (internal) gate-driver channels at 100 kHz, then drops back into a low-power sleep until the next timed demo cycle. Everything has to run bare-metal in C, using STM32CubeIDE and the HAL/LL libraries. Core behaviour • Interrupt-driven state machine orchestrating a ~15 s demo cycle with a configurable cooldown between runs. • Timer/PWM generation for the three channels. • Continuous ADC and I²C sampling of the Hall sensors, with simple averaging or filtering as needed. • Battery management for a single-c...
...expose isolated digital and analogue I/O, and provide standard fieldbus options such as Modbus-RTU over RS-485; extra Ethernet or CAN is a plus if it fits within the available board footprint. Acceptance is straightforward: the first-run prototype should power up, enumerate over the chosen bus, toggle outputs under bench test, and meet 500 V isolation on every opto-isolated channel. I’ll handle firmware once hardware is proven, so clear pin maps and test points in the documentation are essential. CAD files in Altium or KiCad are both fine, as long as Gerbers, pick-and-place, and BOM (with second-source parts) arrive in standard formats. If this scope is clear, jump straight into the schematic draft; I’ll supply the I/O count and enclosure dimensions as soon as we st...

I’m midway through an ESP32 project that interfaces with EMV-compliant hardware and I’ve hit a wall with persistent code errors. The firmware compiles, but crashes as soon as the EMV routines are invoked and I need a fresh set of eyes to trace, debug, and stabilise the stack. Alongside the functional fix I’m gathering detailed power-consumption measurements. I’ve already set up basic logging hardware for the analysis, but I want you to refine the sampling code, capture accurate readings across the EMV transaction cycle, and highlight any spikes that could be smoothed out. What I’ll hand over: the current PlatformIO project, logic-analyser traces, and my preliminary power logs. What I expect back: a clean, crash-free codebase with clear comments, a sho...

I maintain a series of Infineon Tricore 29X-based embedded devices, yet the original firmware documentation is long gone. To keep our product line evolving I must first confirm that you can take an unfamiliar Tricore image apart, understand its structure, and adjust it cleanly so new features can be slotted in. Here’s how we will proceed: after you share a brief outline of your prior embedded reverse-engineering work, I’ll send over a small, self-contained Tricore binary. Your task will be to locate a targeted routine, identify the data structures it touches, and return a patched image that demonstrates a functional change (full instructions arrive with the test file). If your patch runs as expected on my side, we can move straight into the larger projects that involve ...
