Thank you in advance. My idea is to use an interrupt to trigger a task Why interrupt can work well but the signal can't trigger task? Is there any one can help me?
Drew Davis, Let me express my sincere thanks to you. My program is working very well now.
Are you using os_send_signal() instead of isr_send_signal()? Interrupt service routines are only allowed to call the isr_* versions of the functions. Here's a thread with someone with a similar problem: http://www.keil.com/forum/docs/thread1561.asp
