ucos for linux port代码可以在: 我的资源中下载。
1:说明
主要对ucos中的task创建,消息队列,消息邮箱,信号量,互斥量的使用进行了举例说明。对不同的模块的测试:可以通过不同的宏定义来实现。
#define UCOS_BASIC_TASK_TEST 0 //基本任务的创建
#define UCOS_MSG_QUEUE_TASK_TEST 0 //消息队列
#define UCOS_MAIL_B0X_TASK_TEST 0 //消息邮箱
#define UCOS_MEM_TASK_TEST 0 //内存管理
#define UCOS_SEM_TASK_TEST 0 //信号量
#define UCOS_MUTEX_TASK_TEST 1 //互斥量
