      TomChiron reacted to jmarsh's post in the thread Teensy 4.1 serial USB crash with Like Like.
      I would strongly recommend reading 5 bytes at a time (one complete packet) rather than reading as much as possible and then parsing it in chunks of 5. Otherwise there's likely to be a split packet due to usb transfer boundaries that will throw...

      TomChiron replied to the thread Teensy 4.1 serial USB crash.
      I would not expect problems with this amount of data over USB. However, cable ethernet could be more reliable which I would prefer. As I understand the USB port from the Teensy 4.1 is connected to the Raspberry Pi. So how exactly can you see...

      Until now I was running a huge project with WS2811serial and FastLED 3.6.0 on Arduino IDE 1.8.19 and Teensyduino 1.58. Teensy 4.0. Updated now to Teensyduino 1.59. FastLED version 3.6.0 is used as before. No problems here. I will check with the...

      I see it as decision about aesthetics. Of course there are differences. If the higher effort is it worth for you that's great. I like that you are putting so much passion in your project. Looking forward to seeing the result!

      TomChiron reacted to Salchicha's post in the thread USBMidi & USBHost Conflicting? with Like Like.
      As I was creating the small program to post here I got it working, the problem was I hadn't populated the chord bank it was trying to play, not sure why it was crashing the teensy though but its working ok now.

      Not sure if I understand your reasons against LEDs. Using WS2812 or WS2811 LED pixels would be technically much easier than building so many outputs with PWM for analog signals. You could have full control of color, fading times and would be...

      Would it be enough for you to deactivate the auto programming in the Teensyloader? You have to choose the right port/Teensy in any case. This would prevent to accidently program the wrong device.

      TomChiron replied to the thread Teensy usb midi problem.
      Have you checked that this is not a problem in the sketch? Is the behaviour the same if you are using a simple example sketch?

      How does it sound if you connect a speaker? What do you measure if you just use the + and - from the speaker out? Connecting the "-" of the speaker out of the class d amplifier to any other ground can mess it up.

      How do you connect to the Teensy outside the IDE? Where and how exactly do you "get 0"?

      Looks really great! Would you share what type of soft pots you exactly used?

      The problem is solved, I resoldered everything and my bad soldering turned out to be the problem. Thank you everybody for help, have a nice day guys.

      WildBill (Arduino forum) Helped me get the OLD codebase compilable on Arduino. (Teensy 3.2) I developed the handheld and the GUI. Then worked on rewriting a bunch of the code to integrate it on the tiny little screen. Its working pretty well...

      Made a quick and dirty test of how the Beatmaster (cheesy name 1) plays with its older brother the Sidmaster (cheesy name 2). The Sidmaster was the first project where I a) used Teensy and b) made my first semi-advanced pcb. The Sidmaster is a...

      Hi! In the interest of sharing Teensy-based "fun but not rocket-science level" stuff here is a short clip from my standalone sequencer project based on a 4.1. It currently has 7 tracks which can be set to control midi devices on serial or host...

      I can confirm that using several I2C devices on the same bus together with the audio board is working. I am successfully using a display and accelerometer.

      I was curious and checked with a Teensy 4.1. Nothing connected the mouse.ino sketch shows: USB Host Testing 960 Plugging in a (wireless) mouse shows: *** Device HID1 46d:c534 - connected *** manufacturer: Logitech product: USB Receiver ***...

      TomChiron reacted to PaulStoffregen's post in the thread Teensy 5 release with Like Like.
      Normally I don't comment on future products, but I can in this case confirm no new Teensy is currently in development. The focus for 2024 is software, both new features and catching up to a massive backlog of contributions and suggestions and...

      More layers, more Perlin Noise, more complexity, more beauty (hopefully).

      Short update: Improved visual quality and overall look and feel. The little bar graph under the Shuffle button indicates the progress of the transition between parameter sets. Now, a Full Auto mode is present, too, meaning to periodically...

      TomChiron reacted to h4yn0nnym0u5e's post in the thread Two audio boards on a 4.1 with Like Like.
      Yes - there's various threads and web pages around which give more-or-less comprehensive information on how to do it. The info pane for the QuadI2S objects in the Design Tool is a good starting point. The Teensy 4.x can comfortably manage 4i4o...

      I intended to develop a user interface for controlling AnimARTix parameters. However, I got a bit carried away and ended up creating a simulator instead. This simulator allowed me to delve into the concept of transitioning between different...

      I'm currently working on a versatile realtime rendering thing which is meant to generate procedural animations based on very few parameters. Stuff like spiral, caleidoscope, tunnel, lens, twist, rotation and so on, all based on multi layer...

      I finished a prototype and also added a WS2812 RGB LED. The prototype works as I expected. If anyone is interested in manufacturing it please contact me at firebirduino@gmail.com I will give you Gerber files and BOM with 100% open source.

      TomChiron replied to the thread cube 15x15x15.
      I would also assume at first it could be a problem with power or ground. The data signals are generated in each LED as a new fresh signal for the following LED. If the problem starts at a certain LED it could be that there is one faulty. Looking...

      A simple Arduino Nano or so could do the job (*). Sending some commands and parameters via serial connection or so. Possible with one TX pin on the Teensy via soft serial if necessary. The communication part is the only additional effort...

      TomChiron reacted to Pio's post in the thread Stereo Plate Reverb for Teensy4.x with Like Like.
      Just implemented a new tap_tempo function which can be called via MIDI clock callback, footswitch or something else. Here is a short sample of delay synced to a drum track with MIDI clock sent via USB: Another interesting feature is if just a...

      Hello all! I received a lot of support from this forum trying to get this project off the ground, so I figured I should share some of the results as well. Warning: this project is stupid. Maybe the dumbest thing I've ever spent my time on. But...

      I did: uninstall Arduino 1.8.19, made sure that the directory is completely deleted. Reboot Windows. Re-Install Arduino 1.8.19. Re-install Teensyduino. Problem still there. :( I noticed that the settings haven't been removed (opened last files...

      Thanks for the information. Part of the verbose output was in my initial post. Below is a bigger part of the output. I cannot see anything about duplicates or that Arduino IDE is using another, wrong copy of any library. Or I am missing something...

      I have it compiling now using Arduino IDE 2.2.1. Was hesitant to use it because good old Arduino seems to run stable and reliable and I wasn't used to the new GUI. Maybe this is the time for me to change. For now I won't invest more time in...

      Thanks for checking. These settings do not make a difference here. (I understand that the USB type affects only the standard USB port and has no effect regarding the USB host functionality?) I tried it now on another machine (laptop with the...

      I am having problems to compile a scetch using USBHost_t36.h where I am completely stuck now. Even the "Basic.ino" (from MIDI) example is not compiling anymore. I don't understand what is going on here from the error messages. In the past it...
