1. 串口1收发。
计算机上利用串口助手，设置串口参数：“2400，8，N，1”（即：波特率2400bps，8个数据位。无奇偶校验位，一个停止位），顺序发送10字节的HEX数据到STC-B板，STC-B板将接收到的10字节数据再以倒序方式经串口1发送回计算机。

2. 串口2通信（RS485连接，或TTL Uart连接）。
两块STC-B板1和2通过串口2连接（485接口上：A、B、GND，或EXT上：P1.0（RXD）、P1.1（TXD）、GND），设置串口2参数：“1200，8，N，1”。STC板1往STC板2发送5字节数据，STC板2接收数据，计算它们的累加和，并将累加和的低8位通过LED灯显示，验证结果是否正确？（STC-B板1需多换几组数据验证）。

3. 红外无线通信。
与第2题的操作一致，仅两块STC-B板通信方式选用IR红外无线连接（而不是串口2）。注意：同一房间内，同时开启红外通信可能会互相干扰。

4. 实时时钟。
初始化DS1302实时时钟芯片，并将其“时分秒”信息以“时时—分分—秒秒”格式显示在数码管上。然后验证“STC-B学习板”上的实时时钟在断电后，其时钟靠板上的纽扣电池仍能正常走时。

5. 非易失存储。
数据可以在掉电情况下保留在非易失存储器（M24C02或DS1302）中的某个单元上。设计一段小程序：上电后，读取出非易失存储内某个单元数据，并将其值显示在LED灯上，再将这个数据+1后写回这个单元。分析这样的程序，如果拔插“STC—B学习板”电源（或按板上“RST”复位按键），会出现什么现象？（说明：DS1302需要靠纽扣电池才能在掉电时保存数据）

6. 收音机。

8. 温度值计算。
10位精度采集热敏电阻ADC值，编写程序（查表、或线性插值方法等）换算出正确温度值，并在数码管显示出来。热敏电阻参数10K/3950，（具体见“案例测试”中提供的参考资料。可设有效换算温度范围-5°C～+85°C）。

9. 扩展模板。
外设模块中超声波、编码器、电子尺…选取一个，能在数码管上显示相应物理量数值。

10. 直流电机。
设计简单程序段，用两组参数（“50%速度、正转”，和“30%速度、反转”）分别设置直流电机，并接上直流电机观察不同参数时电机转动情况。
