simulating the interrupt

Posted by krishna kumar on April 18, 2008
Hi ALL,

I am using freeRTOS ARM STR91 demo files in IAR tools for serial driver(UART),where i want to simulating the interrupt for UART DRIVER .After debugging the files i displaying character in DR register OF UART, but i cannot see character display in I/O Terminal window and i dont know whether IRQ interrupt is working where IRQ is displayed as expired or trigged in interrupt log window..how can able to work interrupt in simulater,can anyone suggest me..

I don't think (although I might be wrong) that IAR will simulate interrupts from peripherals without first setting it up specifically to do so. It will simulate interrupts from the core itself, but even then I'm not sure how accurately. You will have to check the IAR manual for this one.

Regards.

yes,i can see interrupt register of UART are set when interrupt is occured.Before debugging the files interrupt is displayed as pending in interrupt setup window and after debugging interrupt is set as expired,so it means the interrupt is working..
