The interrupt services routine of Timer 0. *---*/void ...
Hence, as soon as you have a delay function inside an ISR, and the same function in the main code, interrupts _will_ be disabled in the external copy, _even if the interrupt is not enabled_. So if you have a routine for timer0, using interrupts, this will have to wait till the d...
Besides the configuration, how can I implement the Interrupt Service Routine for this eTimer watchdog? Regards, Rafael 0 Kudos Reply 11-18-2019 03:14 AM 1,255 Views mariuslucianand NXP Employee Hello , For implementing the ISR eTimer watchdog, you have two...

Hello guys. A simple routine to utilize interrupt of timer 0 every 444 uSec isnt working. Following is the code. Could anyone plz help with trouble shooting it as after hours of wasting time on it I couldnt find fault. Crystal = 4.194304 Mhz ...

pxa_timer_interrupt中断处理函数 =>c->event_handler(c);也就是tick_handle_periodic系统时钟函数 =>tick_handle_periodic =>update_process_times =>run_local_timers =>raise_softirq(TIMER_SOFTIRQ); 这里仅仅是触发了TIMER_SOFTIRQ软中断,那么在什么地方处理我们mod_timer添加的timer定时器处理函数wlan_check_tx...
