STM32F103C8T6_WIFI_Heating_system
Dependencies: mbed mbed-STM32F103C8T6 eeprom_flash Watchdog PinDetect DS1820
- Bluepill STM32F103C8T6 Heating system
- _This project is core part of bigger heating system project!_
Features
- Reading temperature from four DS18B20 sensors
- Making a decision about switching on/off heater and pomp
- Executing simple user commands from UART
- Storing state parameters to program memory (EEPROM emulation)
