Hi,
I am new to this and I can not figure out how to set up interrupt driven serial communication on AT91SAM9260. I need to use USART3 and all I want is to have interrupt when data received.
This is what I have so far. Not sure if any part of it is true or not, but here it is. Can anybody help me on this?
Thanks.
cyg_uint32 serialIsr(cyg_vector_t vector, cyg_addrword_t data)
{
hal_interrupt_mask(CYGNUM_HAL_VECTOR_US3);
diag_printf("Interrupt worked...");
hal_interrupt_acknowledge(CYGNUM_HAL_VECTOR_US3);
return CYG_ISR_HANDLED;
}
/* Declare the ISR variables. */
cyg_handle_t serialInterruptHdl;
cyg_interrupt serialInterruptObj;
cyg_vector_t serialInterruptVector = CYGNUM_HAL_VECTOR_US3;
int main(void)
{
...
cyg_interrupt_create(serialInterruptVector,
0,
0,
serialIsr,
0,
&serialInterruptHdl,
&serialInterruptObj);
//hal_interrupt_configure(serialInterruptVector,0,1);
HAL_INTERRUPT_ATTACH(serialInterruptVector, serialIsr, &serialInterruptHdl, &serialInterruptObj);
hal_interrupt_acknowledge(CYGNUM_HAL_INTERRUPT_US3);
hal_interrupt_unmask(CYGNUM_HAL_INTERRUPT_US3);
HAL_WRITE_UINT32( SAM9_UART3+_UART_IER, 0x00000001 );
HAL_WRITE_UINT32( SAM9_UART3+_UART_IDR, 0x00000000 );
while(1)
{
...
}
}

look at packages/devs/serial/arm/at91/current/src/at91_serial.c at
ecos repository,
it contains complete example how to do that, may be you can just use
it, without working with hardware.
