Thanks for the clarification. I kinda assumed at first that it should be 0-39 but was confused by the readings. i fixed the code and added a troubleshootINT just to see if I was messing up the currentARRAYslot...
First quick note: Arrays in c start with index 0.
So valid indexes for :: float tappedPATTERNarray;
would be to and this would be right:
if (currentPATTERNarraySLOT > 39){
currentPATTERNarraySLOT = 0;
}
SOLVED!
Thanks for the help! It was that particular Windows box. The problem Teensy worked just fine on Linux and on another Windows box, but won't work on the original Windows box, even after a reboot. I think...
I feel embarrassed asking this, but I would like to send the output from the prop shield audio to my blue tooth speaker via the speakers line in. I can't figure out how to wire the connection. I cut a audio cable and...
Hi all,
My goal with this sketch is to have two buttons. Holding one button while tapping on the other creates an array full of millisecond intervals. I can't for the life of me figure out why the array 'slot' starts...
Hi everyone,
I've got a few more Teensy modules and a couple of OCTO28_ADAPTORs on the way and have dusted off a 3.2 and a 3.5 to be able to run strings of Pixels. My ultimate goal is to be able to control the RGB...
Some nice T_4 details on yet another thread. Sounds like the potential is there. Frank asked what I was wondering when I saw 2MB for Flash - having a static write area onboard will be useful. If the ESP folks unit can...
Technically, it's supposed to be possible. But this is one of hundreds of things I've not yet actually tried.
If you look at figure 30-1 on page 1477, you'll see the diagram showing the flash arbitrator which is...
Maybe. I believe the way the ESP folks do this involves a partition setting, where a portion of the chip is set aside for filesystem and can't be used for code.
I'm going to consider this sort of thing much later,...
Sounds like all is well, indeed it is a tiny difference - I just wanted to make sure there wasn't 'one more thing' needing attention that might break something more significant later. My counts of cycles is just over...
Yeah - HyperFlash - didn't even get as far as finding available parts to see size or cost - new and developing - assumed they could be more than the MCU. Showing off indeed.
Did you settle on a Flash size? I'm not...
Apologies - I edited around and had got pixels.show() after the clear in setup but this wouldn’t do anything. It seems to not do anything until loop() starts
Hey Guys,
I have made a basic laser harp (9 string, red lasers firing into LDR's) using the teensy and the audio library. I have it wokring and its seems quite nice only the strings from the audio library don't sound...
Definitely not using Hyperflash. The chips are physically too large to fit and they're far too expensive. Performance wise, they only help if you have a huge program where you need a lot of code that executes directly...
If we want to have this merged into Teensyduino public releases, I think we'd better expect to require a special preprocessor definition for the extra pin numbers.
Say, #define MK66_extended_pins or #define...
Congrats! Looks like a nice project for those who need many I/O and peripheral pins and who do not aim for 1/10" breadboard compatibility. I don't see this in concurrence to the T4.0 which will most probably win a price...
Slightly updated, a new render is below and a new schematic attached.
Minor update since v1.0-rc3: Added USB0 +/- to the through hole headers as well as VREGIN_0. VREGIN_0 is the other half of the muxed power...
I got it working :D ! I hope the title of this thread isn't too vague, I'll certainly be more specific next time. I am not 100% sure what the difference between the working and not working code is, except I moved the...
With your IDE hex I get:
Interestingly the "Microseconds for one run" and the Dhrystones per Second" are exactly the same as I get with VisualTeensy. Anyway, since the differences are very small (100018/100008 =>...
Thanks for the added detail. I wasn't sure if updated gcc might have any awareness of such hardware organization and help prep for it to minimize stalling. Using 4 bit QPI, okay I wasn't sure if one of the more...
Hello
Not sure if this is intended behaviour but it seems odd to me. I have some WS2812B neopixels connected to pin 8 on a teensy 3.2 - using the below code the pixels flash to full after pixels.begin() and until the...
Regarding the new hardware, there's a consistent theme of "it's complicated"....
Yes, the flash memory is 4 bit QPI DDR clocked at 60 MHz. So the raw data rate, minus command overhead, is 60 MByte/sec. When...
I have been working on a project. where i have to measure change in resistance with the help of another reference (should this reference resistor value be small??) which is basically a voltage divider. The voltage...
If it helps, here's a schematic of a fully pinned out Teensy 3.6 I've been working on. It has not yet been built, I'm working on some minor changes (hopefully the last revision, but the changes are feature additions to...
I agree. You will also need to edit 'boards.txt' to use c++17. I use a makefile to compile the project I have that uses std::variant, you can have a look at my compile and linker options, these would be the same that...
Yes and no.
Yes, an upgrade will happen eventually.
But no, not "anytime soon". Definitely not before Teensy 4.0 is released.
An update to the arm_math.h library (aka CMSIS-DSP) will probably happen before the...
Have you tried that problematic board on other computers? Ideally you might trying Linux or a Mac, if you have access to any such machines. That might help you to know whether the problem is on the Teensy side or the...
Hi Mike, Sorry I've been offline for the last couple months. Been consumed with delivering RTK units for a small fleet of drones. Your YAKF sounds interesting, I'll take a look!
You and Brian were talking about...
Yes, I understand that programming is over HID, but it seems to be a related USB issue to my USB serial problem, as programming over USB HID also has problems with this Teesny -- it does not automatically program...
Thanks, that's good to note. I'll check into why that's happening to see if there's another solution.
I can't speak to your questions about power draw, but I'll happily dig into the datasheet and try to verify what...
No.
Because if num == MAXCHANS you will still modify rcvals.
And write past the end of the array.
Either change the sanity check or declare rcvals to reflect the 1 based nature of the channel index.
Given the sometimes-flakey behavior of Windows driver installations, I’m more inclined to be happy that I found a solution rather than obsess over why it worked.
I'm working on a toy laser blaster for my kid's Halloween costume. I've experience programming, using arduino's, etc... but most of my options were messy and complicated but I found the PropShield. I reviewed the...
Thanks, that does seem to be a similar problem to mine.
Although, I'm not sure if this has always been a problem with this particular Teensy. It doesn't make sense to me that I would have to reinstall the Windows...
More likely explanation would be clicking the "skip" button in the installer on the driver step, or when Windows asks you to confirm you want to install the driver, clicking the cancel button. Either of those would...
Please re-read my post more carefully. You have described my problem exactly; the serial port does NOT show up when I load a sketch which has explicitly been compiled with one of the USB serial options. Also, the...
Thanks for the replies.
Turns out, the straight forward code at the ftp site linked by @el_supremo has perfectly adequate performance for my application. No need for anything better in this case. As they say, “better...
Thanks for the replies all. But, the explanation doesn’t quite match the specifics of this case. Recapping:
* Plugged new T3.2 into Win7 computer and it didn’t show up as COM Port -- as expected given Paul’s...
Good to hear you got it working.

The fastest way is to download the arm GCC embedded toolchain as zipfile, and overwrite the original toolchain in arduino arm(watch the paths). Pretty easy.
Flash in T4: 4 Bit parallel access, I think(?) - Like the...
That seemed to indicate the perfect time to update the toolchain - given the nature and power of the pending T_4 and the hope it will good for the coolest new AI with the components in a newer CMSIS (?). Getting that...
Can teensy 3.2 see if I'm pressing a button on connected PC without any software on the PC? Or can I like have a physical button in the keyboard button and it is connected with teensy 3.2 input pins so it gets activated...
I think that actually, PJRC's priority is rather on bringing a new product to market. Thus, I'd not expect a gcc upgrade soon, especially since the actual version works very well with the Teensyduino core files and...
Hello,
maybe this can help
https://github.com/macchina/LIN
The code seems to be for some kind of Arduino Due clone, but it's using only Serial and digitalWrite. So modification for a Teensy should be possible.
...
I'm interested in using `std::optional` and `std::variant` on my teensy project for fun, and I've noticed that teensyduino is still on GCC 5.4
Are there plans to update to GCC 7 or something newer anytime soon? If...
Yes, that would work. As long as they have valid USB connect, they can be programmed.
I have 5 T_3.6's just now on this computer - and all 5 can be sent the same HEX in parallel if desired and multi selected in the...
Did you upload either of the HEX files and see what that shows?
Just realized it was probably one from the IDE that was requested …
Just built and uploaded that with these results:
Three showed 100000,...
So If I want to flash multiple boards, I have to get them connected via USB to the host and then do the stuff with tytools. That means additional cables (or one cable and hubs in nodes) between boards, am I right? In...
Hi guys!
Thank you so much again for your answers.
My apologies for not being more specific. Well, maybe I made a mistake expressing myself, but what I wanted to say it was if the use of the HardwareSerial...
Did a clean compile with the IDE (1.8.5, Settings: 256MHz, fastest + pure + LTO) which gives :
Dhrystone Benchmark, Version 2.1 (Language: C)

Please give the number of...
I am thinking about a custom T3.6 pcb for my product. There will be kind of a "headunit" with power supply, MCU, all needed interfacing hardware for connected sensors plus connectors for expansion modules . Further...
Programming the Teensy is not done via Serial (as on Arduino for example) but via the HID protocol. The serial port will only show up when you load a sketch which has explicitly been compiled with one of the USB serial...
I understand this is a old post, but I have been running into this problem today and I think I found a solution.
When I ran cat < /dev/ttyACM* I would get the same output but I noticed the command would post more...
Ok, I updated it with some safety checks... does this look better?
#include <PulsePosition.h>
#define MAXCHANS 7 // this is nchannels + 1 because the values are in a 1 based array

I'm running arduino on Windows with a Teensy 3.5, and having a problem with Serial over USB on one of my Teensy 3.5 (the other Teensy 3.5 works fine with same USB cable, etc). The serial port does not show up in the...
Here's a simple proof of concept that I have so far using the new approach. EQ and compression is not in use yet but I've used pitch shifting, a delay (personal preference instead of flanger), and reverb. I played...
Yes, I have all grounds connected together. I did another test just a moment ago and made it work by feeding the Teensy and the first transmitter through the USB port. I can use it like this, but I'm trying to...
