Ok, so I just hooked the display up to a separate power supply and everything worked correctly. The program pin was not connected for this test. I checked continuity from the T4 program pin to every pin on the feather breakout, and the only...

Thanks for all the suggestions... Led being on is fine, it has mains supply. I will see if there is room on my PCB for that header... it's really tight. I do have a space about 150mm way in the enclosure where a dedicated second comms PCB could...

I'm struggling to craft a search string for this, so please forgive if this has been answered. For a new Teensy (4.1 in my case - and 3.2 until recently) that has not has an RTC connected or powered, I'll like to detect that the clock is not set...

You have to implement Daylight Savings Time separately. It's not part of the Time library.

Thanks for the Eagle work! Looks like Adafruit meant for the Program pin to be able to disconnect by cutting these pads apart. Unless there's some specific need for the other connected boards to be able to put Teensy into programming mode...

I'm re-designing moving from Teensy 3.2 to Teensy 4.1 timeline.h defines a tmElements structure that has no "time zone" or "time zone offset" that I can see. The solution depends on several things: - discovering the time - from an external...

Here is the PCB layout: And the schematic is attached. The Program pin goes to a pad next to pin 16 [bottom-left]. Paul

Excellent to hear!

Or if you have some idea of which signal might be connected to that pin, can you arrange to have it not connect? The idea is to prevent the Program pin from accidentally being pulled low, which puts Teensy into programming mode where the red LED...

Maybe something unexpected is happening with the Program pin? Looks like *something* connects to that pin on Adafruit's adapter board. Can anyone with Eagle CAD open the schematic and post a PDF copy?

Sorry, I have one of those feather adapters around here somewhere. But Some of the stuff I am not sure about is how compatible is the feather adapter to the Teensy 4.x? Probably most of it is fine, but wonder about the pins at the side...

I am also having some difficulties with MTP. Using the MTP_Teensy I have included MTP.send_DeviceResetEvent(); Which has allowed for the Teensy to remain connected to the PC and refreshing the directory in windows now shows newly written files...

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...

This error means the gcc toolchain doesn't work with MacOS older than 10.14 (Mojave). It definitely does *not* work with 10.13.6 (High Sierra). Teensyduino 1.57 and older had gcc 5.4 which worked on old MacOS all the way back to 10.7 (Lion)...

I’ll figure it out mate, I just need a break to refresh the brain cells

The proper operation with MTP is to do either generating files or using mtp-loop. Well, at least that is the mode that works. Also, after writing to uSD, the PC must be told (e.g. by user) to remount/reset the MTP responder (on the Teensy). when...

Actually the issue is that windows isn't updating the directory listing to show that file is actually being rewritten to again. I just did the same thing but pulled the after doing a cut and paste to PC (of course I waited for the next write and...

Ah, I have zero experience with recent MacOS… Arduino 1.8.13 is not the most recent, but again don’t know what’s compatible with your setup. A search for dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin turns up stuff, but...

Just an addition, if you are intending using the ESP32C3 from battery, the TenStar has an LED always on. I suppose it could be cut/clipped off.

installed teensyduino version 1.58 still cant compile anything

tried installing 1.59 beta #4 there isnt a version for high sierra 10.13.6 installed Mojave version instead, on arduino 1.8.13 nothing will compile now...

I think I tried that and NO it won't. I tried all sorts of action on the PC and they all resorted in Teensy ignoring the file. It's interesting that when the file is opened a file is returned but Teensy then does not carry out any actions on the...

From a Windows perspective, cutting the file from Teensy, means copy the file first and then subsequently delete the original file on Teensy. If you, from Windows, make it a 2-step action like copy the file first and then as next action delete...

I wouldn't be surprised if the inrush current of the 3V3-to-12V boost converter [FAN53315] used on the Adafruit OLED board [see schematic] is too much load for the Teensy 3V3 regulator to power up the Teensy correctly. For testing purposes: is...

I have a system where I gather data and write it to a file every minute. If I cut the file (from Teensy) and paste elsewhere on the PC the Teensy will not re-create the file and write to it. dataFile = SD.open("datalogZ.csv", FILE_WRITE); is...

I tried this, and it didn't really seem to make a difference (I also had a resistor connected).

A little about AsyncWebServer_Teensy41: it doesn't really use the QNEthernet library. It does use the initialization machinery, but then uses the included lwIP stack (via the Teensy41_AsyncTCP library) and not the QNEthernet API. I wonder if...

Which Teensyduino are you using? 1.59 beta #4 has a fix for issues discovered with a different processor-based I²C slave - it might be worth a shot. Discussion on the other hardware can be found in this thread. You may also need to check if the...

Whilst you are developing your project (software wise) I suggest that you use an ESP32C3 board with a connector. It makes programming and re,re,re programming so much easier, just having to plug in the ESP32C3 rather than un plug it from the PCB...

Yeah I feared that I might kill the teensy, but luckily I didn't. It's working as expected.

Thanks Paul, I got it working. I did follow the instructions and it worked. Thanks for pointing it out, I'm able to get the code working on teensy.

I fear you are popping all the analog inputs one by one - 5V is typically instant death to any T4.0/T4.1 pin, or if unlucky the entire chip.

First of all: do not connect the AS5600 sensor to the +5V ! The Teensy 4.1 is a 3V3 device and will get killed when the input voltages are higher than 3V3. When you power the sensor by 5V, the analog output will also near 5V. So don't use the...

Yes, those 8 pins only take up a small amount of space, the rest of the T-01C3 could just overhang the end. The other thing you could do is mount the Teensy to the top of the PCB with the ESP32C3 mounted from below with a slight (say 0.2") offset...

Maybe in future software we should have attachInterrupt() just turn on hysteresis automatically?

Here, on the left, is another cheap, small ESP32C3.

One on the left. I am really short of PCB space.

Which one the little one on the left or the one on the bottom right which has a USB C connector. The one on the left has 2 rows of 4 pins.

Ooh thanks.... Like the small footprint of the connector on that ESP32C3 I will take a look

Just had a look at the WizFi360 and I am pretty sure it's an ESP32.

if i send you 50 pounds that should cover it aye. thanks a million. do you want to pm how you want me to pay you and details etc

I think £32.50 for the board (brand new unopened). Carriage I will look into, but looks to be less than £10, it depends what size and weight I can get it down to. Just throwing it in an envelope would be £2.50 but I am not sure about how secure...

I use ESP32C3s connected via Rx/Tx - 500000 bps is hast enough for me and easy to debug - send as text until sorted, then change to send binary data. Below is a picture of the system I use, I acknowledge that it is probably much larger than you...

Hi all. Been a while. I plan to add WiFi ability to my Teensy 4.1 project, and need to keep the footprint down. Found the WizFi360 modules.... not sure what they are like. https://www.wiznet.io/product-item/wizfi360/ Any recommendations on...

Hello BriComp, Im from New Zealand but still keen. How much for it including shipping? im located in: Town: Dargaville Region: Northland Post Code: 0310 New Zealand.

I have some T3.5's if you are interested. Where are you? Given that you are looking at 1275cc A Series it could well be in the UK...Oh perhaps not given the time of day of your post.

Hello all, I would like to build the speeduino Dropbear ECU but getting the T3.5 is quite a challenge and i would like to use the T4.1 but will it drop in. I have watched @noisymime youtube video and it looks like he placed the teensy one pin...

Hallo, I want to build a yoke for X-Plane with 2 incremental optical encoders feeding A & B signals to an Teensy 4.0, and 2 DC brush motors providing the force feedback on the X axis and Y axis. I have two DC brush motors (MCG ID2300-E2 )with a...
