Based on Xingshun HK32F030M microcontroller learning board

1. Introduction to HK32 learning board resources

1. A red LED power indicator light and a green LED debugging indicator light.
2. One power reset button RST, two debugging buttons KEY1 and KEY2.
3. DHT11 temperature and humidity sensor interface.
4. 0.96' OLED display interface (IIC).
5. CH340 serial port receiving and transmitting circuit (connected through the jumper cap on the left).
6. ST-LINK debugging interface (with reset RST).
7. All pins of the main control have been lead out for easy expansion.
8. 

2. Simple entry code sharing

1. test1_led: Light up an LED (LED flashes on and off)
2. test2_key: Key input control related LED lights on and off
3. test3_uart: The transceiver configuration of the serial port communicates with the PC through the serial port (printf has not been debugged well)
4. test4_oled_dht11: The OLED display shows the temperature and humidity data measured by the dht11 temperature and humidity sensor (refreshed once every 1 second).
5. ······If you have more classes and more homework, let’s do this first...

Note:

• The above codes refer to the sample codes of the punctual Atom STM32F1 series tutorials.
