Hangshun-EDAMCU

Using the domestic Hangshun MCU chip HK32F030MF4P6, with the support of the domestic Lichuang EDA development software, components, proofing rolls, etc., the following functions are completed:
1. Indoor temperature and humidity detection: The MCU reads the temperature and humidity sensor DHT11 data and transmits it through SPI or I²C ( Control the OLED to display the current temperature and humidity through short-circuit cap switching) communication method;
2. Human body infrared sensor, light and dark sensor: sensing the proximity of the human body triggers the OLED to display the current temperature and humidity, detecting the darkening of the room and the approach of the human body, triggering the light and OLED display Front temperature and humidity;

3. Sound and light alarm: If the data collected by the MCU exceeds the high and low limits of temperature and humidity, it will control the buzzer alarm and light flashing;

4. SWD mode download and debugging, 232 serial port communication.
