OK,
I need more processing power for I2S data processing
I'm considering to simply stack one teensy over another.
the two teensy will run different programs on the same I2S data
I assume I cannot simply solder all pins together.
In particular
I assume that all 3.3V output cannot be connected together
SPI and Serial lines, as far as they are used for outside communication should be driven only by one system at a time
Inter Teensy communication using SPI or Serial needs obviously crossing lines
digital pins used for communication can be connected straight, but with SW duality.
in general
There are no analog signals only digital signals
Only one teensy at a time will drive I/O
So big question, are my assumption correct and could it work?
