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.

I've got an application right now that's using a bytewide output port on the Teensy 3.6, to ensure that all of the bits of output change at the same time. I managed to figure out how to find enough...

Thanks for the help! Is this an area where I should be exploring the use of DMA? Admittedly it's something I haven't played with yet.

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...

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?
...

Got it, thanks! Now it compiles just fine.

The following code compiles under TeensyDuino 1.35, but does not compile under 1.36



#include <ADC.h>

// Snip //

//adc->setReference(ADC_REF_3V3, ADC_0);
adc->setAveraging(4, ADC_0);...

Which pins are the differential ADC inputs on the Teensy 3.6?

Thanks for the help!

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...

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 to both of you for the links! Here's what ended up working for me. I had Code 43, tried the fixes recommended for that issue:

1. Powered down both computers. Still Code 43.

2....

I'm getting "unknown device" in the device manager, for two Teensy 3.2 boards. These boards were both working yesterday. I'm finding it hard to imagine that I killed them, since I didn't do anything...

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...

The problematic code is:


#include <usb_serial.h>
usb_serial_class usbcs;

The error message is:


Arduino: 1.6.5 (Windows 7), TD: 1.28, Board: "Teensy 3.2 / 3.1, Serial, 96 MHz optimized...

New user here. Is the ADC module verified for the Teensy 3.2?

Update: Looks like everything works. The module is nicely organized and easy to use. Thanks!
