Posted on March 31, 2017 at 00:23yes it's confusing now, suppose to be simple, only I don't know yet
how to do it ? May be you know and someone else here does ?
I tried to run the second thread after the first thread finish, and from
the second thread back to the first one, and do it endlessly, flip flop
from the first to the second.
So every thread has to have an endless loop ? and will be suspended
by osThreadSuspend(NULL); , how can I start it ( what's the opposite
command API for it )?
Ok, I'll draw it and post, thanks
This is what I can learn from the STM3210CEval example, do I need those
endless loops ?
==================================
static void LED_Thread1(void const *argument)
{
uint32_t count = 0;
(void) argument;
{
count = osKernelSysTick() + 5000;
/* Toggle LED1 every 200 ms for 5 s */
{
BSP_LED_Toggle(LED1);
osDelay(200);
}
/* Turn off LED1 */
BSP_LED_Off(LED1);
/* Suspend Thread 1 */
osThreadSuspend(NULL);
count = osKernelSysTick() + 5000;
/* Toggle LED1 every 400 ms for 5 s */
while (count >= osKernelSysTick()) <==internal LED timing loop
{
BSP_LED_Toggle(LED1);
osDelay(400);
}
/* Resume Thread 2*/
osThreadResume(LEDThread2Handle);
}
}
/**
*/
static void LED_Thread2(void const *argument)
{
uint32_t count;
(void) argument;
for (;;) <=== do I need this forever loop on each thread ?
{
count = osKernelSysTick() + 10000;
/* Toggle LED2 every 500 ms for 10 s */
while (count >= osKernelSysTick()) <==internal LED timing loop
{
BSP_LED_Toggle(LED2);
osDelay(500);
}
/* Turn off LED2 */
BSP_LED_Off(LED2);
/* Resume Thread 1 */
osThreadResume(LEDThread1Handle);
/* Suspend Thread 2 */
osThreadSuspend(NULL);
}
}
