Hello wdmaudiodev people!
I have an APO-related technical implementation that I'd like comments on
please.
The scenario:
- I have an APO doing a DSP process
- I have external hardware connected to the PC via Bluetooth LE that is
constantly generating data
- I want to pass that data to the APO to modify its processing
parameters accordingly
Here's what I have already:
- The APO runs alongside a complementary Property Page, which I use for
once-off, or rarely-used parameters
- Handy but doesn't provide a solution for my requirement
- The APO runs alongside a complementary Windows Service, which I use
for detection of hardware insertion/removal and the like
I have recently experimented with using my Windows Service to receive data
from my BLE hardware and write it to a Windows registry key that hangs off
my audio device's Properties Win Reg node. I can configure my APO to
listen for updates to the Audio Device's Windows Registry Properties and in
this way I can pass the data from my BLE hardware to the APO.
My data rate is not super high: I get about 50 bytes at a rate of 100Hz
(that is to say: 50 times a second I get 50 bytes of data).
And so to the question(s): is the scheme outlined (Windows Service
receives data from HW & updates Windows Registry; APO gets update
notification and retrieves data) fit for purpose? Is there a better way
that someone can outline?
Thanks!
Culann
