接到21iC客服电话说要个快递一块STM32F411 Nucleo板子，正好要做一个多组机器人的项目，这下STM32F411 Nucleo强大的Arduino功能可以用上了，真是高兴啊呵呵！！
无语中，搞基了半天图片愣是传不上去，:L:curse:

拿到板子赶紧插上USB先体验一番，一插上去弹出来一个盘符“NUCLEO”瞬间一头雾水，有木有！！后来搞明白了原来写好的程序编译后生成的XX.BIN文件可以直接复制到此处啊，确实好用

上官网升级固件去喽。。。下载-安装-搞定！！
参考网上的mbed在线编程整出了一个LED小程序测试了一下，按动按键，LED灯开始以自己设定的不同频率开始闪烁了，挺不错的，呵呵！
主程序如下
#include "mbed.h"

DigitalIn mybutton(USER_BUTTON);
DigitalOut myled(LED1);

int main() {
  int i=0;
  while(1) {
if (mybutton == 0) { // Button is pressed
i++;}
   myled = !myled; // Toggle the LED state
   if(i==1)wait(0.005); // 200 ms
   if(i==2)wait(0.1); // 200 ms
   if(i==3)wait(0.5); // 200 ms
   if(i==4)wait(1); // 200 ms
   if(i==5)i=1; // 200 ms
  }
}

来了兴趣挡都挡不住啊，再来个串口打印测试，呵呵！！下好程序，打开串口助手选择相应的串口号，看！！收到了

把用mbed编写的主程序贴出来吧，看着是不是很简单！
下边就要好好地研究研究PWM了，开始为多足机器人控制做准备了
#include "mbed.h"

//------------------------------------
// Hyperterminal configuration
// 9600 bauds, 8-bit data, no parity
//------------------------------------

Serial pc(SERIAL_TX, SERIAL_RX);

DigitalOut myled(LED1);

int main() {
  int i = 1;
  pc.printf("Welcome to Stm32-M4 !\n");
  while(1) {
   wait(1);
   pc.printf("This program runs since %d seconds.\n", i++);
   myled = !myled;
  }
}

满怀信心的打开了常用的keil软件，发现竟然没有 Stm32F411 ，失望中..........

于是下载新版 keil 5.13。。。。。。安装中。。。。好不容易弄好了  还是没有找到STm32F411REXX

继续努力中。。。。。。。为12路独立PWM奋斗:dizzy:
