uart interrupt

[Altera_Forum]

hi ! 

i'm trying to use interrupt in NIOS II ide for the uart. Are two days that i study this problem . I saw sw development and reference handbooks , and found different informations about uart core and hal api functions , and also read a lot of  driver devices and .h files . I found also an example writing by Kira and use it for my case  the code is :  # include "count_binary.h"  volatile int t; volatile int uart_0;  static void handle_uart_interrupt(void* context,alt_u32 id) {  t++; IOWR_ALTERA_AVALON_PIO_DATA(PM_OUT_BASE, t);   }    int main(void) {   IOWR_ALTERA_AVALON_UART_CONTROL(UART_0_BASE, 0x180); alt_irq_register(UART_0_IRQ,&uart_0,handle_uart_interrupt);      while( 1 )   {    }      return(0); }  but not run .On my development board i can see the led switch on when  a caracter arrive , but the interrupt doesn't work  Somebody know if i forget something else ? thanks ciao  walter

Hi, 

is it possible that your interrupt service routine does not clear the interrupt? may be, you can try to write zero to the status register?!
