I'm trying to play back audio from an sd card on the teensy 4.1 and simultaneously write to a display using spi. If I write too much to the display at one time I hear drop outs in the audio stream. Is there a way around this?
I assumed the built in sd card was on a separate spi port from the one on pins 10,11,12,13. Is that true?
Is there a way to set the display spi priority lower so that it doesn't block the audio stream?
