VendorLedRefresh() missing

Post by ztrail »

When building 2i10o10xsxxxx_mix8, LEVEL_METER_LEDS = 1, for the XK-MC board, I get an error for missing function VendorLedRefresh().

Am I missing a library?

And, in general, I'm clueless as how to use these defines and what they are supposed to do.

LEVEL_METER_LEDS
LEVEL_UPDATE_RATE
LEVEL_METER_HOST

I assume they power the LED array to indicate signal strength. No documentation I can find.

Any ideas?

Ooo - that's an old feature. It existed on an earlier version of USB Audio but was never ported to an updated version of boards.

VendorLedRefresh() was the function that drives the VU LEDs after levels have been calculated. There's an example in app_usb_aud_l2 which drives LEDs via some shift registers.
