I need to bring up the on-chip EMAC on my NXP board so it can reliably handle data transmission over Ethernet using UDP. The hardware is already powered and running the latest NXP SDK; what’s missing is a clean, well-structured EMAC setup that can move payloads out of RA...automatically after reset with a valid DHCP-assigned or static IP (your choice, just document it). • Continuous UDP traffic at 100 Mbps for five minutes without dropped frames. • Source is clean C, builds in MCUXpresso (or plain Makefile) without warnings. • A one-page markdown or PDF notes pin assignments, clock tree tweaks, and any errata-related work-arounds. If you’ve tuned EMACs on NXP, STM32, or similar Cortex-M parts before, this should be straightforward. Looking forward...
I have an off-road RC platform that I want to turn into a fully autonomous vehicle. The goal is for the car to steer itself, manage throttle and braking, and handle lights/indicators without human input while still allowing me to take over with a transmitter when needed. Here’s what I need from you: • Hardware interface: integrate your preferred control board (Arduino, STM32, Raspberry Pi, or similar) with the existing ESC, steering servo, and LED system. • Software stack: write the embedded code and higher-level logic that handles path-planning, obstacle detection, and failsafe switching back to manual control. • Feature completion: automated steering, speed regulation, and programmable light sequences must all work reliably on rough terrain. Acceptance...
I’m updating the firmware for an STM32-based design and need an experienced C++ developer who is comfortable inside STM32CubeIDE. The codebase already compiles and runs on the microcontroller, but several features still require clean, well-structured implementation, performance tuning and thorough testing directly on the hardware. You’ll be working exclusively with STM32 microcontrollers; no FPGA or other targets are involved. Please be ready to pull the current CubeIDE project from my repository, build it as-is, and then extend it in C++17 (or later) while respecting the existing HAL layer and project structure. Deliverables • Updated CubeIDE project with the new or fixed functionality fully integrated • Clear build instructions and a short change...

Solar Support: Mini panel for trickle charging in sunny environments. Efficiency: Ultra-low power consumption in standby (e.g., <1µA draw) to achieve 1-year life. Technical Components (Suggested) Microcontroller: Low-power MCU like ESP32 or STM32 for button logic, LED control, and power management. Positioning: Built-in GPS module (e.g., u-blox) for coordinate acquisition (though pre-programmed, it could verify on activation).

I now need the MCU’s built-in temperature sensor brought into that same workflow s...temperature fields appear without breaking my packet format. • Comment the code clearly and provide a short note on calibration constants and any compensation formula you apply. Acceptance will be based on successful compilation in STM32CubeIDE, correct temperature values shown on my console over a 15-minute soak test, and no regressions in the existing radar data flow. If you’ve worked with STM32 HAL/LL or bare-metal on the G4 series, this should be quick. Feel free to suggest refinements; I’m flexible on implementation details as long as the deliverabl...

Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry.

I am ready to move fast on a custom sonar project built around STM32 hardware (CubeIDE + HAL). Your task is to create production-grade firmware that: • Captures long-range sonar returns through the onboard ADC and a TUSS4470 (or comparable) front-end, with signal conditioning tuned for maximum range performance. • Streams that data in real time using a compact, binary UDP protocol—both transmit and receive paths—so it plays nicely with an existing mobile-app protocol. • Listens for run-time commands such as gain adjustments, start/stop, mode selection, and ping-rate changes, then acts on them immediately. Deliverables I need: 1. Well-documented STM32 firmware source code. 2. A clear protocol reference (frame layout, timing, byte ordering, c...

The mechanical chassis and system architecture are already defined, and I’m now looking for an experienced STM32 firmware developer to implement the motor controller firmware.

I am integrating a line-level audio source (peaks up to 5 Vpp) into the 12-bit ADC of an STM32 that only tolerates 0 V–3.3 V. I need a compact conditioning stage that: • shifts the bipolar signal so it NEVER dips below ground or exceeds 3.3 V • offers a user-selectable gain from unity to about ×10 without degrading audio quality • runs happily from the 5 V rail already present in the system (I’m open to clever alternatives if there is a clear advantage) Please deliver a clean, production-ready schematic (Altium, KiCad or PDF) together with simulation proof—LTspice, TINA-TI, Multisim or similar—that demonstrates headroom, distortion figures and clipping behaviour across the full gain range.

I have an STM32F4-based design that talks to an SD card through the SDIO interface and also exposes the same storage over USB. Using FatFs I can open, read and write files without trouble—until the system sits idle for roughly five minutes. After that pause every file call returns FR_DISK_ERR, the volume refuses to remount, and only a full reset clears the fault. Sleep mode on the card is already disabled and I have double-checked power-management settings on both the MCU and the card itself, so the issue appears to lie elsewhere in the SDIO/USB/FatFs stack or in the way I handle timeouts. What I need now is solid firmware-level troubleshooting, a clear explanation of the root cause, and code changes that let the software recover automatically when the error occurs rather than for...
Project Title: Design & Prototyping of Low-Power STM32 Controller (PCBA) for Water Valve Project Description: I’m building a battery-powered board around an STM32 that can sleep for years (10+ year target), wake up on an RTC or LPTIM tick, read a water-pulse flow meter, and drive a 9V latching solenoid valve. I mostly just need someone who can build it. Preferably in Australia. The core requirements are simple yet strict: • Ultra-Low Power: The micro must stay in Stop mode with the RTC/LPTIM running and draw single-digit µA (

I need a compact, microcontroller-based gateway that sits in-line on a CAN-FD bus and removes or forwards diagnostic frames according to rules I supply. The core of the design should be a device with native CAN-FD support (an STM32, S32K, dsPIC33 C, or any equivalent you recommend) paired with a standard FD-capable transceiver so the board can operate at 500 kbps arbitration and 2 Mbps data rates without external glue logic. Beyond the hardware, I also require firmware—written in C or C++—that initialises the peripheral, listens for every frame, and applies real-time ID filtering (e.g. allow 0x700–0x7FF, block all others). Filter rules must be easy to change over UART or USB so I can refine them in the field. Deliverables • Schematic, PCB layout (Gerber/...

You are free to choose the MCU family you’re most comfortable with (STM32, PIC, MSP430, or similar) as long as the firmware is well-documented and the control algorithm delivers a clean sinusoid under varying loads. Efficiency, thermal performance and fault handling must be considered throughout the design.

I need a compact 4-in-1 ESC that can reliably push 60 A per phase on up to 8 S Li-Po packs while running the open-source AM32 firmware.

I have a small board built around an STM32 microcontroller (STM32L010F4P6) and I simply need firmware that drives two standard 5V fans from PWM output. The speed of the fan should be adjustable with the PWM output (5 different settings). There is a push-button that will be used to change the speed when pressed.
