C++ osMessageCreate函数代码示例

/**************************************************************************//**
 * @brief
 *   Main function is a CMSIS RTOS thread in itself
 *
 * @note
 *   This example uses threads, memory pool and message queue to demonstrate the
 *   usage of these CMSIS RTOS features. In this simple example, the same
 *   functionality could more easily be achieved by doing everything in the main
 *   loop.
