I am basing a driver on the sysvad sample and using wavert to connect to a
SPI device connected through USB (nuvoton). The firmware is representing the
device a virtual USB com port and as a HID device. The SPI device is a
keyword spotter device. I am able to communicate with the device using the
protocol through the serial port that they provided. I have the following
questions or comments:
WaveRT seems to expect a hardware buffer that is shared between the device
and applications. Can this still be used for this scenario?
WaveRT seems to be required for WHQL signing and for implementing WaveRTWaveRT is not required for WHQL. It can’t be, because higher level players
enhancements for a wake on word keyword spotter.
the device is presented as a serial port and hid device and writes/reads toHow is that possibly fast enough for streaming audio?
the SPI device are through this interface.
