stm32ccu6基于HAl库的开发

硬件情况：

代码使用方式：

模式一：

模式二：

感谢声明：

硬件情况：

淘宝上面20几块绿色盗版开发板（支持正版），st_linkV2烧录器

然后是导师的要求：

我们已经买了这个板，准备用它做一个直流电机控制的电路

我们用1个光电门检测旋转的起始点，另外1个光电门检测旋转位置。

基本要求有：

1、检测到起始点后输出另一个光电门的脉冲，用1个门电路控制脉冲是否输出；

2、检测到起始点后按规定的时序输出脉冲；

3、能和上位机通信，工作模式由上位机定。也可以通过引脚的电平组合定工作模式。

目标方案：

采用F401CCU6系统板，控制输出。PWM脉冲输出速度，工作模式上位机通信确定。

具体方案：按键a（KEY2B0）确定模式1，2：串口输出 "模式X" ，

按下按键b（KEY3B1）：串口输出（模式一）“请输入设定个数和设定输出PWM组（为了方便连续实验）”OR（模式二）“请输入设定t/T，输入循环次数”

在按一次按键a：

（模式一）开始检测光电门PWM，当稳定时，串口输出“开始工作”，检测脉冲单片机计脉冲数至设定个数，输出设定PWM（控制光电门输入脉冲，是个数组，最多可存储10个）

（模式二）开始检测光电门PWM，当稳定时，串口输出“开始工作，当前T:XXX”，检测到宽脉冲，计1，输出1.单片机计数至设定个数。输出0；

前前后后反正中途变方案了好多；

下面是干货，各种模块

用stm32ccu6开发板的人知道，像这种，资料很少，不向正点原子那种官方例程搞好，然后ctrl+c+v,so easy.它只有一个虚拟串口+定时灯+GPIO口的例程，一些F4库他还会删删减减，更为要命的是，有些同学（比如我）只会keil,不会说stmcubex(是真的强，狗头狗头)，移植程序就很难。

但是主要在于三个程序：

pwm串口捕获，输出指定pwm,虚拟串口收发指令并控制（上位机还没有做好QAQ）

pwm输出：

开始输出。正点原子官方HAl例程直接整。

pwm串口捕获：

检测最终版：鬼才知道我修了几版。个式bug。

主要是主要就是声明一个接口，声明一个timer定时器，声明一个中断，clock切换，开始输出。，然后在main.c，设定数值，设定检测流程。

虚拟串口收发指令并控制：

有一说一这部分有点久远了，先对借鉴的作者说一声感谢！！

主要是stmccu6这例程，本身就有CDC_XXX,这样的输出

另外为了进行控制

if(my_RxLength!=0){for(i=0;i<my_RxLength;i++){//HAL_Delay(500u);//设定个数设定if(my_RxBuf[i]==97)//当输入串口a时+1{shedinggeshu=shedinggeshu+1;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",shedinggeshu));}if(my_RxBuf[i]==98)//当输入串口b时-1{shedinggeshu=shedinggeshu-1;if(shedinggeshu==-1){shedinggeshu=0;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number Error%d\r\n"));}CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",shedinggeshu));}//设定输出PWM组if(my_RxBuf[i]==99)//当输入串口c时确定输入一个PWM{pwmnum=pwmnum+1;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set pwmnum: %d ge\r\n",pwmnum));pwmflag=1;}if(pwmflag==1){if(my_RxBuf[i]==97)//当输入串口a时+10{pwmcount=pwmcount+10;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",pwmcount));}if(my_RxBuf[i]==98)//当输入串口b时-10{pwmcount=pwmcount-10;if(pwmcount<0){pwmcount=0;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number Error%d\r\n"));}CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",pwmcount));}if(my_RxBuf[i]==101)//当输入串口e时+1{pwmcount=pwmcount+1;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",pwmcount));}if(my_RxBuf[i]==102)//当输入串口f时-1{pwmcount=pwmcount-1;if(pwmcount<0){pwmcount=0;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number Error%d\r\n"));}CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",pwmcount));}if(my_RxBuf[i]==100)//当输入串口d时停止修改PWM,pwmcount放置pwm100倍{pwmflag=0;//pwmzu[pwmnum-1]=pwmcount;CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the end set pwmnum: %d ge\r\n",pwmnum));CDC_Transmit_FS(sendAdct,sprintf((char *)sendAdct,"\r\n the set number: %d\r\n",pwmcount));}}}for(i=0;i<my_RxLength;i++){my_RxBuf[i]=0;}}

就是把串口读取到的存储在一个数组，要用时挨个取出，为了之后不出错，还要即时清空。

cdc串口输出就有一点迷，会警告，总程序共有十个警告，但不影响使用。

希望能进行探讨在代码过程中发现什么问题。也希望能发表一下自身见解。

代码使用方式：

用flagmode来区分工作，

先进入flagmode==1:判断进入哪种工作模式，模式一串口输入“q”，模式二串口输入“p”，

模式一：

进入flagmode==5:输入工作数据，workliza,worklizb来判断模式几，然后我们是模式一，需要检测到特定脉冲，而我们则是用高电平时长检测，检测至设定个数，输出设定PWM波，所以一个整数，一个数组。输入一次“a”，设定个数+1；输入一次“b”，设定个数-1；输入一次“c”，设定数组值+1；且输入一次“g”，设定个数+10；输入一次“h”，设定个数-10；输入一次“e”，设定个数+1；输入一次“f”，设定个数-1；输入串口“d“时停止修改PWM,pwmcount放置pwm100倍。设定好一切之后，按一次”r“；

进入flagmode==2:按下”p“,输出当前高电平时间，再按下”s“，进入工作。

进入flagmode==4:串口输出“开始工作，当前T:XXX”，检测到宽脉冲，计1，输出1.单片机计数至设定个数。输出0；

会有一个回退程序：按下”r“，进行回退到flagmode==1；

模式二：

进入flagmode==5:输入工作数据，workliza,worklizb来判断模式几，然后我们是模式二，就是检测到一个指定信号脉冲，开始启动，知道当前高脉冲时间，然后不断输出一个时间比值上为1+t/T的脉冲，和检测次数。所以一个数组，一个整数。；输入一次“c”，设定数组值+1；且输入一次“g”，设定个数+10；输入一次“h”，设定个数-10；输入一次“e”，设定个数+1；输入一次“f”，设定个数-1；当输入串口d时停止修改zhouqibizhicount,zhouqibizhicount放置t/T倍。输入一次“a”，设定个数+1；输入一次“b”，设定个数-1设定好一切之后，按一次”r“；

进入flagmode==2:按下”q“,进入工作。

进入flagmode==4:然后会输出当前周期”T，按下”y,会自动输出当前高电平时间，输出pWM。检测到设定个数，停止

会有一个回退程序：按下”r“，进行回退到flagmode==1；
