Python on the host side of embedded systems: reading microcontroller telemetry over UART, storing it, simulating sensors, testing.

RU: Python на стороне компьютера: читаем телеметрию с микроконтроллера по UART (JSON), пишем в SQLite, симулируем датчики, тестируем. TR: Bilgisayar tarafında Python: mikrodenetleyiciden UART ile telemetri (JSON) okuma, SQLite'a kaydetme, sensör simülasyonu, test.

🗂️ Projects

Folder	What it does
projects/uart_sqlite_gateway/	gateway: reads one JSON line per measurement from an STM32 / MSP430 / ESP32 over UART (115200 baud) → SQLite table measurements (timestamp, temperature, current, vibration)
projects/ntc_serial_reader/	Arduino sketch reads an NTC thermistor on an analog pin and sends JSON at 115200 baud; Python finds the board's port automatically and prints the temperature
projects/sensor_sim_gateway/	sensor simulator (JSON at 1 Hz) + gateway that reads it, project layout src/ tests/, pytest

Loading

🚀 Run

cd projects/uart_sqlite_gateway
python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt
# set PORT in src/iot_gateway/gateway/main.py (e.g. /dev/tty.usbmodem*)
cd src/iot_gateway/gateway && python3 main.py

cd projects/sensor_sim_gateway/src/sensor_sim && python3 simulator.py   # prints JSON every second

🛣️ Next

• Publish to an MQTT broker (paho-mqtt is already in requirements)
• Live plot / dashboard, then simple anomaly detection on current and vibration
