IoT MQTT Temperature Logger + IP configuration by website. Created for STM32H743ZI using LwIP.
- Temperature measurement using thermistor and ADC,
- Cyclic temperature logs by MQTT,
- LEDs controlled by MQTT and website,
- Changing IP and subnet mask by website,
- IP configuration stored in flash memory.
Tested with Mosquitto.
/presence - STM says Hello!
/led - LED control
/temperature - Temperature logs
/flash - STM sends IP address if it's read from flash (not default)
- LD1_ON, LD2_ON, LD3_ON - turns selected LED on.
- LD1_OFF, LD2_OFF, LD3_OFF - turns selected LED off.
- LD_STATE - STM will reply which LEDs are on.
