STM32 Jobs

I need production-ready firmware for an STM32F303 that turns the microcontroller into a front-end for high-speed digitisation of SDR signals. The chip’s ADCs must sample the incoming RF-baseband stream, move the data through DMA with minimal latency, and prepare it for onward transmission over a fast serial link (either SPI or UART—whichever achieves the cleanest, sustained throughput on this part). The core of the job is sensor-style data processing: capture, buffer, and pre-format the raw samples so that an external host can handle the heavier DSP. No motor-control, no classic temperature or pressure sensors—just clean, reliable handling of SDR-grade analogue input. Key expectations • Continuous, gap-free acquisition at the highest practical sampling rate for t...

I'm looking for an experienced hardware engineer and PCB designer to deliver schematic and layout for a mixed-signal control board on a tight timeline. This project is best suited for a senior engineer familiar with high-speed signals (~80 MHz SPI) and signal integrity preservation, who can start immediately. The board at a glance: - STM32H753ZI MCU (Cortex-M7, 480 MHz) + flash + USB serial - 14 high-speed analog inputs (~300 kHz range) from precision sensors (mix of bipolar and single-ended in the low-volt range) - 14 analog outputs (mix of ±10 V differential and ±10 V single-ended for driving external actuators) - External high-speed SPI ADC and DAC (you will pick these to read from analog sensors and perform analog output) - Single 12 V or 24 V DC input, on-boar...

The power stage of my transformer-based Li-ion home UPS is already proven in the lab—what I still need is the brains. I’m looking for a seasoned embedded developer who can build clean, modular firmware for an STM32 that will bring the unit to life and withstand regulatory scrutiny. Scope of work • Battery management: implement reliable CC/CV charging logic and tight thermal protection. Per-cell cut-off at specific voltages can remain configurable for later revisions, but the two listed functions must be rock-solid in this release. • Inverter section: the first priority is crisp, low-distortion SPWM generation that tracks load changes smoothly. Overload and short-circuit handling already exist in hardware; firmware hooks to report and latch these events will be pa...

Solar Panel Cleaning Robot Prototype Development We are developing an automated rooftop solar panel cleaning mechanism and need an experienced freelancer/team for complete mechanical, electronics, and prototype development. The product is a linear sliding brush/wiper-based cleaner for solar panels. The brush will move left and right across the solar panel surface like a wiper. It should be safe for solar glass, cost-effective, lightweight, and practical for Indian rooftop conditions. Work Required 1. Mechanical Design Design a complete sliding cleaning mechanism for rooftop solar panels. Use a non-rotating linear brush/wiper system. Design should be suitable for small rooftop solar systems. Create a rail/slider mechanism using bearings, guide rails, or cost-effective alternatives. Pre...
