calling CoInitOS(). 3) When initializing the OS, the system will close the OS scheduler and create the first task-IdleTask. 6.1.2 CoStartOS() Function Prototype: void CoStartOS(void); Descriptions: System start running. Parameters: None Returns: None Example usage: #include "CCRTOS.h" #define TASK0PRIO 10 OS_STK Task0Stk[100]; OS_TID Task0Id; void Task0 (void *pdata); int main(void) { System_init(); CoInitOS(); // Initialize <strong>CoOS</strong> … Task0Id = CoCreateTask (Task0, (void *)0, TASK0PRIO , &Task0Stk[99], 100); … CoStartOS(); // Start <strong>CoOS</strong> } void Task0 (void *pdata) { ... for(;;) { ... } } Note: 1) Before calling CoStartOS(), you must create at least one of your application tasks, or OS would stay in CoIdleTask () all the time. 2) When the OS starts, the task scheduler is unlocked and then start the first task scheduling. 42
6.1.3 CoEnterISR() Function Prototype: void CoEnterISR(void); Descriptions: System enters the interrupts. Parameters: None Returns: None Example usage: #include "CCRTOS.h" void EXTI0_IRQHandler(void) { CoEnterISR(); // Enter ISR … /* Process interrupt here */ … CoExitISR(); // Exit ISR } Note: 1) When the system enters the interrupts, increase the interrupt nesting counter- OSIntNesting by one. 2) CoEnterISR() and CoExitISR() must be used in pairs. 6.1.4 CoExitISR() Function Prototype: void CoExitISR(void); Descriptions: System exits the interrupts. Returns: None Returns: None 43
