Close serial monitor and it starts writing to the sketch again, with the hello world text prefixing the counter.

Finally got a port in arduino and serial monitor to open. Now I see the numbers and it’s no longer writing to the sketch.

Ah well it gets even weirder. The teensy is outputting this hello world message with the counter. Must be the blink sketch? But it’s writing code directly into arduino sketch file at the cursor position.

Odd . Every time I plug this other teensy in I get this hello world text appears in the ide in my code at the cursor position. The integer increases each time. Still can’t see it as a port, but teensyduino responds to a button press on tge 4.1. I...

So I’m compiling and uploaded to my t4.1. Everything goes weird. The teensy does not boot. I can no longer see it as a port in arduino. I check the pc, leads to a restart. Get a blue screen. Finally manage to get the pc back up. Open up arduino...

Thanks for your detailed answer. However, I am confused about calculating W25Q64JV speed as MB/S.

First things first: are you using pinMode() to set all your ADC pins to INPUT_DISABLE (to disable the digital input schmitt trigger) ?

When first programmed the Teensy will automatically have the Compile/Date time. If you wish to get that date/time on subsequent powering of the Teensy you can use the code below: Serial.print("Compile: Date "); Serial.print(__DATE__)...

Hi! I've seen in other posts that it's possible to use the USB_MIDI_AUDIO_SERIAL flag to use teensy as a USB soundcard and write to the Serial console. Is it also possible to communicate using OSC on the same USB port? I've tried but I couldn't...

For my project I want to measure the phase between two input signals. The input signals have a sinusoidal shape and the exact same frequency. The frequency can be in the range from 100 Hz to 10 kHz. The AudioAnalyzePhase_F32 object from the...

Sorry I don't know the CYD... Mine are mostly RED... In some places in the code, I have simply winged it. That is I setup a sketch that echos the raw touch points and figure out MIN/MAX values. Like in one sketch I have: #define TS_MINX 337...

Hello! Just wanted to share with you that everything works! Thanks for all the inputs and comments! Now I'm running at 1MHz: I have a problem with digital bleed and running at lower speed helps reducing it a lot. What happens is that when I...

Using a 320 x 240 2.8" touch screen with ESP32...what is being called, by some, the CYD (Cheap Yellow Display)...I am having difficulty figuring out how to translate the position of a touch (e.g. X = 2077, Y = 2025) to the pixel position as...

Maybe you should ask for advise about Arduino's boards on Arduino's forum. Of course it's ok to talk about Arduino's products here, but as a practical matter of reaching people with knowledge and experience using those boards, asking in the...

I just got my Teensy's ordered! Was looking at the ref manual and see that at least some of the lp-uarts have the "single-wire mode" that we need for SDI12 communications, so that is a good start. I haven't really dug into the T4's serial code in...

Good morning @mjs513, I guess I should probably dig out a T3.6 to see if we can get any clues on the difference between it and the Micromod. Although I don't think I have those controllers. I completely agree with you, that their current...

Just chiming in on this thread to thank both of you for helping me also with my own little project Trim/Faders for channel 7&8 on my 833 It works flawlessly thanks to the info I got from your conversation :) Currently working on a breadboard...

Must admit, at this point I don't recall what prompted the .1 and .2 updates, but I'm sure it was very minor stuff. 1.57.2 from Boards Manager in IDE 2.2.x is essentially the same as the 1.57 installer for IDE 1.8.x.

Another interesting question might be, do you really want 1.57? As for example if you look at the Arduino Board manager (Arduino 2.x), you will see the list of downloads of: And there the 157 is actually 1.57.2, I don't remember if The .1 and...

I know that I am sort of late to the game. It has been a while since I have played with MTP. As far as alternatives, I believe it was either MicroPython or CircuitPython that implemented something like TinyUSB or the like, which allowed you to...

Apologies, yes that is what I meant. Thank you for the help!

If by that you mean from PC to Teensy and vice-versa - Not that I know of.

Thank you!

Looks like Adafruit shipped my older on Wednesday (it was placed on their website over the weekend) and the tracking info says it's due to arrive early next week. Please understand if the lockup problem does turn out to be a bug in any of the...

I would be interested to know how it all works out. Another titbit, if you are sending to sleep and waking it up via Teensy, it takes the EST32C3 something like 50ms to become compos mentis.

I sent a request to Adafruit asking them to mention cutting those pads apart if using Teensy 4.0 and the 128x64 OLED Feather.

same, cant find version 1.57 for mac os

While the above solution did work, since I upgraded Arduino IDE from 1.8.13 to 2.2.1 it stopped working. Is there an other way to enlage the serial buffer on a teensy 4.1? i used to edit the file Hardwareserial3.cpp and edit the RX_buffersize...

O, you're right again. It's difficult to see, and the schematic shows an open, but that pad is actually connected on the PCB. Yeah, that would explain the issue. Paul

It's connected to the APX803 (voltage monitor). The problem is probably that adafruit intended it to reset the controller, but that's not what the Teensy's PGM signal does.

Argh...you're right. Thanks. But even then, no active electronics connected to that RESET# pin as far as I can tell. Paul

Look at the layout of the pins rather than the numbers... it appears pin 1 on the OLED board (labelled RESET#) connects to pin 16 (PGM) on the feather board.

Well, I'm glad to hear it's working by just cutting the pad on the Feather Teensy adapter. But I don't understand it though. There is nothing connected to pin 16 on the OLED board. Pin 16 is bottom-right on the image below. Perhaps...

I am working on a custom board using the same processor as the Teensy 4.1, but I am having issues getting the processor to start up correctly. I get 1.1v at VCC_SNVS_IN but nothing on VCC_SOC_IN. This is my first BGA board so I was wondering if...

Seems like a safe idea. Interrupt pins floating for digital use seems like it would never be commonly useful.

Confirmed. After cutting the trace the OLED and Teensy work as expected when powered through the T4.0 USB connector. I have two Teensy4's that are soldered to feather adapters. I have cut the programming pin trace on one of the two boards. The...

The emulated EEPROM uses a portion of the flash memory chip to store its data. You can find the W25Q64JV-DTR Datasheet on the Teensy 4.1 page tech info section. For the raw speed specs comparable to those raw SD specs, turn to pages 89-90...

Just to confirm, did cutting those pads apart make it work without requiring the extra power source? Or asking another way... now that Teensy 3.2 is discontinued and people will only use this adapter for Teensy 4.0, should we ask Adafruit to...

Hi, I am working on a report for a competition, and I should compare SD card and Teensy 4.1 Emulated EEPROM for storing a small data set. But I couldn't find enough information for Emulated EEPROM. You can see my comparison table and missing...

Seems this is only an issue based on the program used to open the files. Using an alternative has solved that problem.. As for transfer speed with a sample 4MB file takes just over 6 seconds. This is with T4.0 and Audio shield mounted SDcard...

While playing with the Arduino USBHost lib and adding a lib for wired Joysticks I was working with the 2 new controllers that I added to USBHost_t36. PS: The Teensy USBHost_t36 is heads and shoulders more flexible and my 2 cents better (Giga...

Don't remember the transfer speeds we say off hand but I did just check that I can open multiple cards from a micromod buit-in SD card no issues. I am on a Windows 11 pc - also tested on a Win 10 machine a long time back. In terms of writing to...

You may have a ground loop. You probably have an SD card that draws quite some current when writing. And you maybe use a power supply that is dipping when the Teensy draws more significant current. I think the reference voltage for the ADC is...

So I disconnected the program pin by cutting the pads on the PCB and everything works correctly. Thank you all for your help! It is greatly appreciated!
