RTOS SDK - Enable SPI Interrupt

[jhinkle]

This is what I have for initializing a SPI interrupt to occur when the package transaction is done

Code: Select all


   ETS_INTR_LOCK();
   
   _xt_isr_attach(ETS_SPI_INUM, HSpi_Interrupt, NULL);
   

   ETS_INTR_UNLOCK();

   SET_PERI_REG_MASK(SPI_SLAVE(1), SPI_TRANS_DONE_EN);   //  | SPI_SLV_WR_BUF_DONE_EN
   
   _xt_isr_unmask(1 << ETS_SPI_INUM);




The interrupt is not firing so I know something is wrong.

Please advise me where I'm wrong.

I fond very little documentation about this when dealing with RTOS and had to take a best guess on what I found relative to standard SDK.

Thanks.

Solved it.

I was missing _xt_isr_unmask(1 << ETS_SPI_INUM);

I added to the code above -- it works!
