Having difficulty trigger an HWI via McBSP0 transmit - Author Unknown - Nov 2 0:06:00 2001

Hello all.

I am trying to trigger an HWI via McBSP0 transmit but am unable to do
so. I have my system designed to perform some numerical analysis on
an input signal (input signal coming from McBSP0 receive) and once
the signal meets a specific condition, the system would emit ready
signal out of a speaker via McBSP0 transmit. I thought one way to
activate the HWI (I selected HWI_INT10 from the DSP/BIOS
configuration tool with its interrupt source set to McBSP0 transmit
along with a ISR to execute when activated. Note that I have checked
the dispatcher to avoid programming in the HWI_enter and HWI_exit
function) was to set the McBSP0 transmit register (at address
0x018c0004) everything a threshold is met. However, that did not
activate an HWI. Do I have to use PIP objects to activate the HWI
(via pip_put function for example)?

All comments, advices, and suggestions are welcome.

Regards,
A. Feynman

Have you enable the transmit Interrupts on the port itself? Bits 21 and
20 of the SPCR configure the McBSP transmit interrupts. -Devin
