hi thanks for the replay. but as i sad above i used: sorry here is the code: //============================================================================= // Simple test viewer app for several of the USB devices on a display // This sketch as...

At what signal are you looking? Compare it to other FFT representations you like. There is always some playing, making it aesthetic, rounding. It is not 100% precise and cannot be with a limited number of output representations which are shown...

@TomChiron I picked this up from amazon, and it was as easy a plug & play can get. Tiny receiver that i wired into the Teensy 4.1 Host USB pins. Libraries read it with no issues I can tell so far.

I can confirm that it runs correctly on 1.60 beta 3. Maybe I'll make the switch to beta tester. What could go wrong ? :)

I tried it on Teensy 3.2 using Arduino IDE 2.3.3 and latest 1.60 beta 3, running on Linux x86-64. Also prints 7.

Hello everyone. I'm trying to communicate with an STM32 using FDCAN, but right now I didn't success. I'm sending the Teensy code here. Any clue, I don't know what information I can provide, so if any question I'm glad to awnser. The FDCAN specs...

Thanks for checking. Problem seems to occur only on Teensy 3.2 3.5 and 3.6 Not on 4.0 or 4.1

With a 7 port hub you would need at least two hub objects.

Would be much easier to help if you would post your sketch. As a completely blind guess, did you include a hub object in your sketch ?? Mark J Culross KD5RXT

Of the 16 columm, each representing an FFT bin, the highest frequency columns show less amplitude. Agreed, I'm looking for the mathematical relationship between "fft 1024" and Octave binnings. Currently, I'm just playing with trial and errors...

Easily. The screen isn't busy, just the bar graphs which don't take much computation. Plenty of CPU cycles and WiFi capacity left over. WiFi has plenty of bandwidth to carry the audio packets as well, however the time lag tends to be excessive...

Works correctly for me as shown in your post. I'm using T4.1, IDE 1.8.19, TD 1.59, Windows 7 Pro. in setup gdefaultState=7 state=7, gdefaultState=7

For a display, I'm using a 240x240 st7789v LCD. I'm able to hit 60 FPS by clocking SPI at 75MHz, with double-buffering and non-blocking DMA. There's a quirk in the Pico2 SDK where overclocking forces the SPI clock to 24MHz, but you can prevent...

Hello, Yes! I confirmed your latest version (with templated shiftC) restored the performance, while still preventing overflows in the interpolated shading. Thank you!! Here's my profile of the 3 versions, where "Draw:" column shows the...

Hi Paul. I have the flash chip connected to a STM32G474. I use the STM32CubeIDE to configure the SPI to run at mode 0, 2.6 MBits/sec. I use the HAL calls to transmit / receive data over SPI with the flash chip. I tried different speeds and...

Using Arduino IDE 2.3.3 on MacOS 14.6.1 Sonoma, Teensy Loader 1.59 The code below: int gdefaultState=7; void setup() { Serial.begin(115200); while(!Serial); ; Serial.printf("in setup gdefaultState=%d \n", gdefaultState); } void...

What exactly dou you mean by that? For usual signals there is not much energy in the highest frequency bands. Could help to compare with a software device how the used signals look there. Human musical pitch perception works "in octaves" =...

Should be possible, yes. Looks like a good starting point. When you play around with it you can decide later to change the routing, make other combinations, serial effect chains or parts as send effect. It could also be nice to add multiply with...

Somehow the data which is send from Madrix and how it is receiced / interpreted in the Teensy does not match. To understand your question: Do you set numStrips to 4? With the 170pixels per strip you get 4 universes. The artnet sender (Madrix) has...

@sublinear I just pushed a small change that should mostly cancel the slowdown the color interpolation bugfix may have created... Can you pull the newest version of the library from github and let me know if it is better ? Thanks.

You are welcome! Quick update: Yesterday I received by RPI5 (Canakit 128gb SD) and it works nicely. Will update soon to NVME SSD. Note: I am typing this message on it, and I editing files on it using SublimeText4 IDE 1.8.18 installed with...

That is great, let me know how the NVME SSD goes, I think I will want to do that as well.

hi all can someone help me. i have: teensy 4.1, usb cable, usb hub (7port with power adaptor), keyboard, mouse, honeywell 1400G scanner sketch: USBHost_viewer.ino (yes i also have the ili9341 connected) when i connect everything seperate to the...

Thanks Paul, I was able to solve the problem with this info!

Try running teensy_discovery in a terminal or command prompt window. Find it in the package Arduino IDE installed (~/Libraries/Arduino15 on MacOS, .aduino15 on Linux, {AppData}/Local/Arduino15 on Windows). Once it's running, type START_SYNC...

Hello! I am adapting the AnalogIn->FFT->OctoWS2811 exemple for my project. My LED matrix is 16 wide by 79 high. My main issue is adapting the frequencyBinsHorizontal I now (almost) understand the concept, but I have no clue on how to select/tune...

Very cool! Would the single esp32 in the tft screen be able to handle the gui and the communication between the Teensy?

For online buying I tend to use PiHut or Pimoroni, and sometimes Cool Components. The PJRC Store also links to "Oak Tree LLC", but this seems to go straight to $hama$on and give you the usual list of irrelevant and highly suspect results. No...

Hiya folks! I've been meaning to build a module that uses most of the effects from the audio design tool, basically it would select 1 function per channel via a selector pot so only one effect per channel would happen, so I'm thinking this...

If you've changed the VID+PID then the program won't recognize the device. If you've reused the VID+PID but have changed the interface numbers, endpoint addresses etc. then you've broken what the program expects a device with that VID+PID to...

That actually makes sense. Here is my custom usb type: #if defined(USB_CUSTOM) #define VENDOR_ID 0x16C0 #define PRODUCT_ID 0x0482 #define MANUFACTURER_NAME {'T','e','e','n','s','y','d','u','i','n','o'} #define...

Sorry, obviously very little we can do to help here as, we have not seen the USB descriptor data, nor know if it has custom PID:VID... Things I would try include: a) Does it work with TyCommander? b) If you have another Teensy that has USB...

Hei I just recently moved to London and wanted to ask if some of you know any cool shops or spaces I should check out : ) Also i was wondering what the best online supplier in the UK is for buying my next teensy ; ) Cheers Basil

On a 4.1, I want to use the second USB port as the main interface to the PC, still as a device, not host. I need to use a better connector than the micro USB. So I need to move the Serial and SerialUSBx devices to it. Main USB port will not be...

I did not make any changes except to the interfaces. I analyzed all of the USB traffic, and the behavior matches that of the predefined USB_HID type exactly - except that it does not display output on the serial monitor.

Hi, For a Project I use a Teensy LC, it reads in two analog channels, among other things. One of the channels is a good NTC for the PID oven and the other is a TMP37 Sensor which measures the outside temperature of the PID oven. The Teensy LC...

Is the example actually failing because the magnetics aren’t present? I f yes, how is it actually detecting that no hardware is available? I’m sorting out the proper jack but now I’m curious how the micro can detect this. Thanks.

seremu is handled by teensy_monitor, if you've changed the interface around it probably doesn't know how to read it any more.
