That's a great thought, thanks. It could be that the pins are floating before then, and that's why the problem's occurring.
Will adjust and report back if it's still happening.
Hi, so I have Teensy 4.0 acting as an SPI slave. — RE: https://forum.pjrc.com/threads/59254-SPI-Slave-Mode-on-Teensy-4
Everything works when the serial monitor is open from a PC, but when it's not... it seems to try to open a serial connection on the default SPI pins (which are being used for...
OK, that's interesting to hear. I'm a little worried as to why changing ADC0 to ADC1 in the code as a test doesn't work but will keep poking at it. This library's pretty cool.
Hoping to make this work somehow.
I've been playing around with a Teensy board and the one real roadblock I ran into was the lack of a second AudioInputAnalog for stereo audio.
Not a huge dealbreaker, but as I was thinking about workarounds, I thought back to about how there's a second ADC in the 3.1 board only.
Is it possible...
