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...
