Crashing on Mac OS 10.15.3 Downloaded the standalone 1.51 for macOS 10.15, It asked to allow int monitoring on security & privacy, allowed, restarted Teensyduino. selected teensy lc, selected example, neopixel test, crash. I there a way to use the old installer? without having n different...

Sure! I have no problem posting the plans, I designed the cabinet using Fusion 360 and used the it to generate g-code to cnc each side on a cnc router table, so I'm not sure what is the best way to share the project, dimensional drawling? The entire step file of the 3d model? everything? The...

Follow some pictures of the finished project:

I actually tested a bunch of solutions, a small PCB inside of the button got into the way to the mechanism, so that did not work properly. I ended up using APA-106-F5 that are basically round 5mm round ws2810 mounted underneath the button on a 3d printed light defuser.

So I wanted to build a arcade machine, but as everybody else I like LED's, I wanted to have an ws2810 on each button and have them show led patterns and animations when playing and while the arcade is idle. I created a small PCB to help wire everything, I tried to use one teensy as two...

I got it showing as two devices, but both joysticks will have same ID and the OS don't handle that pretty well. Ended up using two teensys-lc and synchronizing the code, I "needed" to have one teensy display led patterns when buttons where pressed.

I think I figure it out, I basically created a new variable inside of the usb desc with the same information of the joystick, than I created a new USB_ARCADE based on the USB_HID and added my new joystick configuration. I cloned the joystick class and created joystick1, and that is it! I now see...

Paul, is this tutorial still applicable for the new releases? after making the changes I don't see any usb interface on my computer.

Is it possible to make teensy show up as two different gamepads? I'm trying to get a custom built arcade machine to work, but I'm having difficult to configure two players with the same gamepad. Retropie and Recalbox expect two different gamepads for two different players. I dont want to use...

Question is pretty simple, I'm having issues sharing the SPI port on teensy-lc. So I want to use the second hardware SPI on it, how do I access it? It is going to drive an ST7735S TFT Display, I could use software SPI but if I can make the hardware SPI work would be great. I know that I need...

I'll be sure to let you know!

Hello everyone, does MKL02/04 support MKL26Z64VLH4 chip instead of MKL26Z64VFT4? I'm going to hand solder a few boards, and would be easy to work with the LQFP version instead of QFN.

I could not make lowpowerlab library work, but RadioHead worked. I'm still having issues, when sharing the SPI with another device (FTF) the radio is dropping too many packages. How can I get the hardware SPI1 to use with the library, instead of the SPI0 ? By the way, of course I'm using...

I'll try the RadioHead library tonight, per the other thread discussion. The issue is definitely on the receive part, I used the teensy to transmit and uno to receive, uno could see the package coming, and would send the ACK back to teensy but teensy would not get it. When I check with the...

Hello Everyone, I'm trying to make two RFM69HCW radios talk to each other without success for 3 days now... I tried the same code on two arduinos unos and it work perfectly. But for the final project I need the teensy (I need more serial ports and drive a small lcd faster than the uno) I...

I missed this thread completely! Sorry... I left the scrolling with a little improvement on my branch on github, I did not made a pull request to paul's branch. I did not want to possible create bugs. Other then that this project is 90% compleate, I had problems making bitlash work with sd...

There are plenty of topics on thsi forum reagarding different ways to program Teensy, none are supported by pjrc and can brick your teensy. Writing your own bootloader is a hugeeee effort, I don't know what do you mean with hardware bootloader and you might be confused on how Teensys work...

very very strange, I don't even have a ~/Library/Developer/Xcode/Templates/Project Templates/ folder. I do have the following: /Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/Library/Xcode/Templates/Project Templates...

Thanks @potatotron, I have a 200 step / rotation motor. And indeed the stepper driver was configured to use a half step! Spoiler: My next project that I'm working on is a rubik's cube solver using a teensy! :)

Hello Guys, I don't have any previous experience with stepper motors, just trying one little project and testing the AccelStepper library but i'm having a problem. I'm trying to use positional based control on my stepper motor, but i'm not clear what the "relative position" actually mean, is...

Very very strange, the installation does not fail, already tried the manual installation and still no luck. My security level is set to install applications downloaded from "anywhere".

I'm actually new using github, hehe... Is this what i need to do to create a pull request?

I'm having a problem getting embedxcode to install on my machine. After running (successfully) the installation I don't see embedxcode as a option on xcode project types.

hey Paul, maybe that happened because he downloaded an old version of the INF file that I linked through an old thread that you posted, could it be? If so what do you think about providing an updated INF file available for download in case something like this happens.

@sumotoy the keyboard is a xbox 360 chatpad, you can get the library and more information here. I needed to modify the original library to work with bitlash and some other timing issues. @Paul yes... they are 3d printed. I'll post all the files on thingverse! :)

is Teensy printing on serial monitor?

Moderator edit: The Teensyduino installer has a signed INF. You should not need to disable driver signature enforcement. Took few screenshots using a virtual machine.

UPDATE: please read Paul's comment below, this step should not be needed, despite it might work for you. Try the following: Go to Start - Then Command Prompt Enter command "shutdown /r /o /f /t 00" Click the "OK" button System will restart to a "Choose an option" screen Then select...

I think this is simillar to this thread Just to make sure that teensy is runing you code do upload this sketch, it should blink the led while printing hello world to the serial. If you see the led blinking that meens that your computer is not finding the drives for teensy, that is strange, the...

It is pretty simple actually. You need to select the serial port that teensy create on arduino IDE. After you upload the sketch teensy will create a serial port that will apear on Tools -> ports (or something like that). Select the port and try open the serial monitor again.

@defragster this is indeed where I was planing to use the scroll functionality on ILI9341 library. I didn't had time to check this issue yet, so many projects, only 24 hours / day, my day job only disrupts my fun. I'll send you a PM with my email, can you send me a Sketch to reproduce the issue?

Hello Guys, I've been working on a [micro] computer based on teensy and bitlash interpreter, the idea was to help me when i just want to test something but don't want to program a microcontroller. I finally got into a stage that my project is sharable. I made a custom PCB with teensy, a...

uhm... doesn't attachInterrupt requires use of the "digitalPinToInterrupt(pin)" on teensy? Try replacing: attachInterrupt(COIN, isrService, RISING); To: attachInterrupt(digitalPinToInterrupt(COIN), isrService, RISING)

Updated the github with resetScrollBackgroundColor, removed the println that I forgot. Thank you defragster! No idea why the library got slower, but for me the difference was acceptable. Should I push it to Paul's github?

Cool! I did not think of that! :) Did you figure it out the issue with Teensy 3.2? I do not have one to test. Can you post a picture of the issue? Thanks!

Not sure if I understood what went wrong here.... did you noticed that the test code has a " while (!Serial)" ? So it will only start printing stuff to the tft when you open the serial monitor, i probably should have removed it. I tested the code on the adafruit tft, I'll test it using the one...

Hello Guys, So I updated a version that I kept of this library that allows easy text scrolling, now supporting the custom fonts, like this video: You can find my branch here: https://github.com/vitormhenrique/ILI9341_t3 Paul, should I create a pull request to add new functions to the...

Hello Guys, Quick question, on the past I created my fork of this library to include scrolling functionalities (basically copying screen memory and pasting shifting the position). I saw that few more methods were added to the library, I'm wondering if is there any new way to accomplish text...

As cartere said it was a typo on sparkfun website, so i was looking the incorrect part number... ops, my bad! Nevertheless, if teensy 3.x++ has the space, I think it would be a nice feature! :)

Well, I think is very difficult for you to guess the percentage of users that need / want a feature unless you sell / provide both options and have a real world data to talk percentages. Another thing is that, adding a feature, by adding a 10 cents part (on my opinion) doesn't hurt.

Have you guys seen the new SparkFun SAMD21 Mini Breakout? Despite is not even close to the power of Teensy 3.X (the microcontroller is more close to Teensy-LC costing almost twice) I like that it comes already with RTC crystal and an integrated LiPo charger. I would love to see those on Teensy 3.X++

The LED will only blink if you code it to blink! just like any regular LED you need to put current through it to light it. Teensy LED is on pin 13, so making it HIGH light the LED. // the setup function runs once when you press reset or power the board void setup() { // initialize digital...

1) For 210 leds / strip I would connect both ends to the power supply. You can check the voltage aat the end of the strip and see what is the voltage drop and decide if that is needed or not. WS2812B leds are very sensitible to the power supply. 2) No idea, it is up to you and personal...

post some high resolution pictures... Teensy don't magically short itself, either you connected 5v to a 3.3V pin or you messed something up while soldering, or applied an incorrect input voltage...

Thanks Guys! The visor is vacuum formed by the way (homemade vacuum forming machine, made for this project) and the mold is 3d printed. Buying a 3d printer was the best thing that I ever did... I highly recommend, and if you can, get a lulzbot one, I'm not being sponsored and anything, i...

For this halloween I made two 3d printed Daft Punk helmets. Used a teensy-lc to control the lights on each helmet with a bluetooth module to control the lighting patterns using my iPhone. I needed to rush on the last day, but it was fine at the end.

Really nice! Thanks for sharing!

I would guess that 99% of code for arduino works on teensy, I had never tested a sensor that worked on arduino (I2C or SPI) and did not work on Teensy. The only thing you need to be careful is that teensy boots faster and arduino, sometimes teensy boots faster than the sensors can respond and...

wow... i wish i got teensys on my birthday! =/

I guess posting more info would be better.... otherwise look's like a spam....
