通过串口将实时电压值打印出来，旋转开发板上的滑动电阻器R11调节电压，LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates ADC single channel continuous sampling, triggering 
DMA transmission function, ADC sampling PA0, triggering DMA transfer data upon 
completion of sampling, Print the real-time voltage value through the serial 
port, rotate the sliding resistor R11 on the development board to adjust the 
voltage, LED1 flips every 1 second.

使用步骤：
1. 接上P2上的PA0跳线帽，将PA0接到滑动变阻器，接上P10上的跳线帽，将串口接到USB。
2. 编译下载程序到MCU，并运行。
3. 可观察到开发板上的LED1每隔1s翻转一次。
4. 旋转的滑动变阻器R11，串口实时输出采样电压。


Example execution steps:
1. Connect the PA0 jumper cap on P2, connect PA0 to the sliding resistor, connect
 the jumper cap on P10, and connect the serial port to USB.
2. Compile and download the program to MCU, and run it.
3. It can be observed that LED1 on the development board flips every 1 second.
4. The rotating sliding rheostat R11 outputs real-time sampling voltage through 
the serial port.
