C Programming Jobs

I need a fully-coded Relative Strength Index indicator that plugs straight into Quantower via its open API. The core requirement is simple: the look-back period must be user-adjustable from the platform’s settings panel so I (or any trader) can fine-tune it on the chart without opening the source. Please keep the script lightweight, coded in C# as recommended by Quantower, and use the platform’s standard drawing and event hooks so it behaves exactly like a native study—automatic repaint on bar close, proper scaling on sub-panes, and settings persistence between sessions. I am only targeting this one technical indicator right now, but if you design the class structure cleanly, adding overbought/oversold bands or divergence logic later should be straightforward; solid...

I’m building a smart irrigation setup that links a Raspberry Pi edge server with several ESP32 nodes in the field. Each ESP32 gathers data from soil-moisture probes, compact weather boards (temperature, humidity, barometric pressure), and inline flow meters, then reports everything wirelessly to the Pi for processing. Here’s what I need from you: • Python (Raspberry Pi) and MicroPython/C++ (ESP32) code that ingests the raw sensor streams, pushes them through an on-device model, and decides—within seconds—whether to start or stop the main pump and which solenoid valves to open. • An ML pipeline: training notebooks, a lightweight model (TensorFlow Lite or similar) and the inference wrapper that runs locally. The model must act on current soil-moisture rea...

I have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate. Stability and reliability are my chief concerns; speed is acceptable once the board reconnects. The task is straightforward: go through the existing codebase, spot whatever is undermining the connection logic, and supply clear, working fixes. Serial logs, event callbacks, power-saving modes, and DHCP handling are all fair game—whatever it takes to stop the frequent disconnects. Deliverables • Annotated version of my original source showing every change made • A concise technical note explaining the root cause and the remedy (1–2 pages) • A quick reconnection stress-test script or steps I can replicate to p...

I want to build a Windows-only application that watches the live screen, detects people—including stylised in-game characters—in real time, and immediately drives a game controller so the crosshair locks onto and tracks that target as it moves. The workflow I picture is straightforward: the program captures frames, an AI model spots the person, and a virtual stick signal (XInput, vJoy or a comparable driver) nudges the aim every frame so it stays centred. Smoothness and speed are critical. On a 1080p feed I’m aiming for roughly 60 fps with no more than 40–50 ms end-to-end latency, so techniques such as YOLOv8, TensorRT or a lightweight custom network combined with OpenCV screen capture should fit. You’re free to choose Python, C++, or another language as long...

I have individual, validated firmware blocks for the STM32L432KBU6 that handle an LIS3DH accelerometer (interrupt-driven), an EM4095 RFID front-end, the MCU’s internal touch-sensing controller, and a UART-based E220-400T22S LoRa module. My next step is to merge these routines into one cohesive, ultra-low-power application on our custom PCB. Power optimisation is the top priority. I want the system to remain in STOP mode most of the time, waking through the LIS3DH interrupt and periodic RTC events. When active, each peripheral must communicate reliably without compromising the sleep budget. Key points • Integrate existing C-based drivers into a single project • Configure and test the STOP-mode strategy, ensuring wake-ups from both the LIS3DH and the RTC function every t...
