   双精度浮点问题

   部分STM32高级芯片具备双精度浮点计算能力，设置方式有所区别，参见：

   慎用RT_IPC_FLAG_FIFO

   除非你有明确理由，非常关心内核对象等待队列排列顺序的先来后到，否则强烈建议用RT_IPC_FLAG_PRIO

   STM32 CAN Bus 的比特率

   STM32的CAN驱动里面代码适配时，有预设的总线时钟。需要核查驱动预设的时钟和你使用的板子的总线时钟是否匹配。如果不匹配，则需要自行修改驱动里面的时钟配置选项，否则CAN总线的bitrate会不合预期。

   scons Windows 平台编译，命令行参数超过 32K 报错规避办法

   1. 打开工程目录下 SConstruct 文件：

   2. 在 objs = PrepareBuilding(env, RTT_ROOT) 这一行前面添加如下代码

   def ourspawn(sh, escape, cmd, args, e):
       newargs = ' '.join(args[1:])
       cmdline = cmd + " " + newargs
       if (len(cmdline) > 16 * 1024):
           f = open('cmd.param', 'w')
           f.write(' '.join(args[1:]).replace('\\', '/'))
           f.close()
           # exec
           cmdline = cmd + " @cmd.param"
       proc = subprocess.Popen(cmdline, stdin=subprocess.PIPE, stdout=subprocess.PIPE,
           stderr=subprocess.PIPE, shell = False, env = e)
       data, err = proc.communicate()
       rv = proc.wait()
       if rv != 0:
           sys.stderr.write(err)
       else:
           sys.stdout.write(data)
       return rv
   
   if platform.system() == 'Windows':
       env['SPAWN'] = ourspawn

   3. 在文件头部导入相应的模块

   import subprocess
   import platform
