作业要求
任务：编程实现系统子功能可能会使用的BSP模块功能。
BSP模块应用训练：
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。初始化启用FM_radio模块。收音机参数设定为91.8MHz，音量6。PHONE接口上插上耳机验证是否正确收到电台？
7. 音乐播放器。用Music模块提供的API实现播放一段音乐。
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。

串口1收发 |
|
编程思路 |
用数组rcvBuffer[10]存储接收的10字节数据，当接收到数据时将数据逆序，仍存储在rcvBuffer[10]中，然后当uart1串口空闲时发送回上位机。 |
|
核心代码 |
unsigned char rcvBuffer[10]; void Uart1_callback() { unsigned int i; unsigned char temp; for (i = 0; i < 5; i++) { temp = rcvBuffer[i]; rcvBuffer[i] = rcvBuffer[9 - i]; rcvBuffer[9 - i] = temp; } while(GetUart1TxStatus() == enumUart1TxBusy) Uart1Print(rcvBuffer, 10); } |

串口2通信 |
|
编程思路 |
发送方：当检测到按键按下时，通过串口 2 发送一组固定的 5 字节数据，同时清零数码管显示；当按键释放时，让数码管显示为空。 接收方：设置串口接收缓冲区，当串口成功接收到 5 字节数据后，进入回调函数，先计算这 5 个字节的和，用 LED 显示该和的低 8 位，同时把和拆成十进制各位数，依次显示在 8 位数码管上。 |

温度值计算 |
|
编程思路 |
用ADC模块测量温度，得到的ADC值存在rt中，由于ADC值有10位，所以要先取低8位（0-255），然后查tempdata表得到对应的实际温度值，最后用数码管显示。 |

扩展模板 |
|
编程思路 |
利用扩展接口实现超声波测距，在 1 秒回调函数中调用GetUltraSonic函数读取测量值，再把结果实时显示在数码管上。 |
|
核心代码 |
int dist; void ShowDistance() { dist = GetUltraSonic(); Seg7Print(10, 10, 10, 10, dist/1000, dist/100%10, dist/10%10, dist%10); } void main() { DisplayerInit(); SetDisplayerArea(0,7); Seg7Print(10,10,10,10,10,10,10,10); EXTInit(enumEXTUltraSonic); SetEventCallBack(enumEventSys1S,ShowDistance); MySTC_Init(); while(1) { MySTC_OS(); } } |

题目名称 |
直流电机 |
|
编程思路 |
利用扩展接口控制直流电机的转向和转速，按下Key1让直流电机以50%速度，100Hz频率正转，因此设置PWM2=50，freq2=1000/100=10；按下Key2让直流电机以30%速度，100Hz频率反转，因此设置PWM1=30，freq1=1000/100=10. |
|
核心代码 |
void DC_motor() { if (GetKeyAct(enumKey1) == enumKeyPress) SetPWM(50, 10, 0, 10); else if (GetKeyAct(enumKey2) == enumKeyPress) SetPWM(0, 10, 30, 10); } void main() { EXTInit(enumEXTPWM); KeyInit(); SetEventCallBack(enumEventKey, DC_motor); MySTC_Init(); while(1) { MySTC_OS(); } } |
