Hello

Im thinking in build a USB dock to connect my Android tablet to my car.

Can i use Duinomite with Android Open accesory protocol, out of the box?

And second, Can i play smoothly PCM audio, stero at 16bit 44.1Khz? Or if the Duinomite can't decode audio as fast, could i use some board like these that have the VS1053 DSP chip to move the audio data from the USB to the DSP by SPI?

My idea is to connect my tablet (WITHOUT USB-OTG) to the car, all by USB (yes, it would be easier to connect the 3.5mm jack, but there isn't fun in that), and using the CAN interface of the Duinomite Mega to conecct to my Car ECU, and Cookpit display

no, you can't Duinomite have USB-OTG and can work with open accesory protocol, Microchip have app note and code, but you have to build and porgram it to replace original Duinomite firmware, i.e. not out of the box

how you will play PCM stereo on processor without audio codec?

If i can't, the idea is to take something like MOD-MP3, and pass it the audio stream from the USB, but i would like to use as less boards as i can.

Could i run usb-host from MOD-MP3-X?
