Hi everyone, Teensy newbie here. Any help / hand holding will be really appreciated
I am trying to work out the following block diagram:
My goal: To read/write some music files directly in to the SD Card in Audio Adaptor from PC via USB cable.
I am able to procure some SD Card reader chips (AU9331, from aliexpress) that is found in USB Card Readers like this (I had to break open one to find what they use).
This is the reference design that is given in AU9331 datasheet. I am also attaching the full datasheet.
I am using a separate Micro B USB socket for connecting the SD Reader Chip to PC. (I am not using the Micro B socket of Teensy).
Is it possible for Teensy to share the SD/MMC Bus with the SD Card Reader Chip? ( It is ok if Teensy can't play music when files are being copied via SD Card Reader chip).
Is there anything in SPI library that I can use?
Am I heading in the right direction? Please guide.
