Tnx Paul - I appreciate the quick reply
Todd

Thanks Paul. Do you have an estimate on when the Teensy 3.2 will be available again?

Yeah I came to the same conclusion. IntervalTimer seems to be a better library. At least it give the same results over the different Teensy models :D

Vindar and Kurt - Thanks! I made the changes that Vindar recommended. Curiously the waveform is inverted(!) and the timing is different between the 3.2 and 4.0. At least the periods are correct...

I'm in the process of converting over one of our products that use the impossible to get Teensy 3.2 to the more available Teensy 4.0. I've turned up a bug in the TimerOne library

I'm running on a...

I'm a new NanoVNA-F owner. Can you recommend a good source for quality terminators?
Tnx!
Todd

It (kinda) lives!!!! Based on Paul's opinion that it was a HW problem I decided to gently attempt to reflow the component side of the PCB using my hot air rework station. That seemed to do the...

Hi Frank - I kinda did that already by sending out a diagnostic message using Serial1 and watching on an oscilloscope doing RS-232 decode. No activity on the TX line. The same sketch worked fine on...

Thanks defragster. No LED indication in a very dark room

I'm uncomfortable applying 3V to pin 13 especially since I am pretty sure the sketch isn't running. The I/O should default to tristate...

Thanks Frank - that is a really good point. I checked the output of pin 13 with a scope but didn't check the LED. The LED test fine (and lights) using the continuity function on my DVM.

I'm having a similar problem like others are having with the Teensy 4. Mine is slightly different and maybe this helps in finding the problem

I bought a Teensy 4 just after they were released...

Sure (once I figure out how to :-D)

Hmmm can't edit my old post - anyway please change the references to 1.29 to 1.28 (the latest issue)

Based on Paul's insight I grabbed a fresh copy of 1.28 and added a 10uS delay between CS_HIGH...

Well I have made some more progress. I don't think that it is a problem in the Teensy though. I suspect that the library is broken from 1.26 to 1.29 but I do not have a real Arduino board to verify...

Thanks and I understand. I'd rather have the T4 sooner! ;)

Hi Paul - I really appreciate your help

So I tore it down, checked the jumpers for continuity and intermittents, added the SO line. No change - black display

I reinstalled 1.46beta10. Loaded...

Sorry I should have attached the pic

Revisitng this topic. Installed 1.46beta10. Deleted Adafruit_GFX and Adafruit_ST7735 from hardware/teensy/avr/libraries folder. Installed the latest Adafruit GFX lib (1.4.8) and S&7735 and ST7789...

Happy Birthday!

I just bought a Rigol MSO5074. A bit higher than your budget of 200EU but inexpensive for a higher end 4 channel scope.
Changing the device software configuration (increased BW,...

Any chance of supporting castellated edges?

A power on reset function. For testing now I just cycle the power supply (I have the USB supply isolated). It would be handy since Teensy loader is always available after the first upload.

If it...

Hi Paul

A reset button would be handy - sometime my power supply is further than an arms length away

I think you forgot to hook up MOSI/MISO (11, 12) :p

Just a thank you to Robin and anyone else involved in shipping product. I placed a small order on Friday morning, received a shipping confirmation the same day and the product was delivered on...

Are you sure you are pin 32? It looks like cross talk to me

Updated Kickstarter beta board w/o issues. Running Win10 64bit Arduino 1.6.11

W00t! My Beta board has arrived. Thanks to Paul, Robin and Erin!

See Table 10 http://www.nxp.com/documents/user_manual/UM10204.pdf Per the spec the minimum clock speed is "0" It looks like the library was setup for quick transfers but I can see where a few low...

I use this one. I like the larger lens and builtin illumination

I'm excited about getting a PCBA soldered by real Goddess! I'm not sure if I should enshrine it or put it in use :p

Congratulations Paul!

When you launched the Kickstarter, where did you think that it would wind up?

For the other features I cannot foresee a need for or haven't figured out how to use yet (ex: DMA). It doesn't hurt that they are there though. Getting access a beta board early influenced what...

$44K in less than 24 hours(!) Quite a bit of pent up demand for the new series

And ordered(!) Now that mere mortals can see the pictures it looks like the Teensy 3.5 and 3.6 share a common PCB but are fitted with different components. Distinguishing between the two is going...

Still broke for me as well ...

So I ran into the same problem today with TimerOne only I am using the Dec 28th issue of the VM plug in, Arduino 1.6.6 and Teensyduino 1.26.

My sketch barfs with the same error as yours but...

Those are reverse polarity diodes. Only one is needed but I suspect that since they came two in a package, Paul paralleled them together.

Now it does look like a better place for the shorting...

This should be added to the quick reference thread
https://forum.pjrc.com/threads/25395-Teensy-Quick-Reference-Code-Examples-Tips-and-Tricks

Thanks! - I assumed that it was some kind of behind the scene trickery. We can I find the AVR section of the Teensy core?

I am moving a bit of code from an ATmega328P Arduino to the Teensy 3.1. I do a fair amount of bit banging by directly manipulating the GPIO ports rather than using digitalWrite calls. The Teensy...

Hi Freto

Markus' youtube video lead me to this thread and your code with the Mario test image motivated me to pick up a Teensy 3.1 and a 32x32 panel to experiment with driving RGB LEDs using BAM...
