& firmware
From firmware analysis and signal processing to secure OTA updates: we build reliable, secure embedded software for industrial requirements — on ESP32, nRF, STM32, and more.
Secure firmware engineering
- Secure boot flow and code signing
- OTA updates with signature verification
- Input validation and buffer safety
- OWASP Embedded Top 10 security review
Protocol implementation
- MQTT, WebSockets, Modbus RTU
- BLE (GATT, provisioning)
- LoRa, NB‑IoT, Wi‑Fi (ESP‑IDF)
- UDP discovery, AMQP
Real-time & low power
- Zephyr RTOS (nRF Connect SDK)
- ESP‑IDF (FreeRTOS)
- Ultra‑low‑power design
- Interrupt-driven architecture
Signal processing (DSP)
- FFT/spectrum analysis (0–250 kHz)
- High-rate ADC via I2S up to 500 kHz
- 4096-sample buffer management
- On-device classification
Motor control & sensors
- SPI stepper drivers (TMC5160)
- PWM control (NEMA 17/23)
- Power sensing (ACS758, INA219)
- RPM/RPS verification and fault detection
DevOps & CI/CD
- PlatformIO in GitLab/GitHub CI
- Automated build and flashing
- PlatformIO (platform-espressif32)
- systemd services and OTA rollout
