Firmware Jobs

ATM NDC application CAM Data is not flowing from the NCR would require a free lancer who can review the state,fit,downloader to make it work.

I’m building a compact, battery-powered torque meter that streams live readings to a smartphone over Bluetooth Low Energy. The job covers three tightly-linked pieces: electronic hardware, embedded firmware, and a cross-platform mobile application that works on both iOS and Android. Hardware & firmware The unit will sit between the torque sensor and the user’s phone. I need a custom PCB that conditions the sensor signal (likely through a strain-gauge amplifier), handles A/D conversion, and hosts a low-power MCU with BLE 5.x. Firmware should sample torque, apply calibration constants, then broadcast the data at a steady, low-latency rate. Power efficiency and a clean-pairing workflow are essential. Mobile application On the software side, the app should discover the met...

Firmware Adaptation for CH591 From CH592

Preciso desenvolver um Módulo de Distribuição de Energia com 18 saídas, inspirado nos PDM15 que já uso como referência interna. O objetivo é assegurar três funcionalidades cruciais desde a primeira versão: proteção contra sobrecarga em cada canal, monitoramento remoto em tempo real e controle individual de todas as saídas. Quero comandar e visualizar tudo numa interface web amigável, acessível tanto em desktops quanto em smartphones; portanto, a parte de firmware e a camada de software devem expor servidores HTTP-REST ou WebSocket que facilitem integrações futuras. Ainda não defini requisitos de compatibilidade com sistemas externos, então o código e o hardwar...

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...
