    Thanks. Since I don't need speed so much as simultaneity, I think it would probably be prudent for me to just use an octal latch. That way I'd be code compatible with any Teensy in the future.

    Fastest possible speed on IntervalTimer

    This program should toggle the LED at pin 13. I've played with values for the timer period in 0.1 microsecond increments. Below a certain value, the LED stops toggling (evident on a scope), and the...

    Teensy 4 ordering of instructions

    It's my understanding that the Teensy 4 is capable of running two parallel lines of code. I have a couple questions about that:

    1. Does the compiler or the processor automatically manage that?

    Question: Is the "reset" pad on the Teensy 3.6 board an input or an output? I'd like to have a functioning reset button, separate from the bootloader button, at least while I'm debugging my app. If...

    Trying to get SPI1 working on Teensy-LC

    I'm trying to get SPI1 working on Teensy-LC. For now I'm using the library functions, though I eventually want to start using the SPI FIFO. Here's a program that I think demonstrates my problem. I...

    Thanks. I was poking around to see if using the functions in usb_serial.h would affect the transmission speed, which it didn't, so it was a blind alley. The more I work with the Teensy 3.2 and...
