[ECOS] eb40a Interrupt, TC

[Carlos Perilla <transfers@phaber.com>]

Well , finally I got two  timers running, with the conf I want, Now I 
need to capture the interrupts that my configuration is generating, as 
long as the TC_SR says the events that I have programed had passed but 
not attended.

I have set the ISR and DSR like this:

cyg_uint32 interrupt_TC1_isr(
               cyg_vector_t vector,
               cyg_addrword_t data) //Based  on eCos book, pag 48
{
  cyg_interrupt_mask(vector);
  cyg_interrupt_acknowledge(vector);
  return(CYG_ISR_HANDLED | CYG_ISR_CALL_DSR);

}
void interrupt_TC1_dsr(
              cyg_vector_t vector,
              cyg_ucount32 count,
              cyg_addrword_t data)
{
  HAL_IO_REGISTER REGISTER;
  cyg_semaphore_post(&TC1_data_ready);
  REGISTER=TC_BASE+TC_CHANNEL1+TC_RA;
  HAL_READ_UINT16(REGISTER,TC1_PERIOD);
  REGISTER=TC_BASE+TC_CHANNEL1+TC_RB;
  HAL_READ_UINT16(REGISTER,TC1_HIGH);
  cyg_interrupt_unmask(vector);
}

And I have created in the CYG_USER_START

 cyg_interrupt_enable();
  cyg_interrupt_create(
               intTC1_vector,
               intTC1_priority,
               0,
               &interrupt_TC1_isr,
               &interrupt_TC1_dsr,
               &intTC1_handle,
               &intTC1);
  cyg_interrupt_attach(intTC1_handle);
  cyg_interrupt_unmask(intTC1_vector);

  cyg_semaphore_init(&TC1_data_ready,TC1_data_ready_counter);
  cyg_semaphore_init(&TC1_trans,TC1_trans_counter);
  cyg_semaphore_init(&TC1_end_trans,TC1_ent_trans_counter);

Im using two other threads to capture and transmit the data I get from 
here, still the Interrupt Isn't captured, and the program keeps waiting 
for the semaphore signal.

Thanks you all.

Carlos Perilla.
