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...

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...

Followups on the other thread. Closing this one. https://forum.pjrc.com/index.php?threads/teensy-4-0-dac-function.74019

I didn't think you would need to do that if you use the code I posted in #27. I don't have time at the moment to double check that but perhaps you could? I recall the (sparse) data sheet does claim the two DAC outputs are synchronously updated...

Hi! I'm associated with the "Tympan" project, which is what was referenced in one of the links above. Our mission is to produce an open platform for developing algorithms for hearing aid research, a platform that is approachable by...

Can you show us photos of the hardware connections? We could make a lot of blind guesses about the problem, but if the problem is a mistake or misunderstanding with the wiring, a couple quick photos are pretty much essential to really help solve it.

worked bro, thanks

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.

Yeah, it did take me a while to revisit looking at the USBHost library since there was so much success already with the code and other devices (for about the past year). I did look back into the installed Teensyduino examples at one point, but...

Should be better documented, but

Found what I didn't know. For USB MIDI Coms sent from one Teensy 4.0 to another, in the Host USB Teensy use: MIDIDevice_BigBuffer usbMidiHost(midiHost); Instead of: MIDIDevice usbMidiHost(midiHost); Working fine now.

What great information! The Tympan Library looks amazing, and is a massive time saver when it comes to coding/debugging. I figured I'd be at that for a long while and that would have been just the basics. I'll definitely be back with more...

By default pinMode configure the pin with a feature called slew rate limiting maybe that's the problem ? void setup() { pinMode(?, OUTPUT); CORE_PIN?_CONFIG &= ~PORT_PCR_SRE; // turn off the slew rate limit } EDIT: Not sure if this will...

I am having trouble with my new Teensy 4.0. Here is my setup: I have the Teensy soldered to the Adafruit teensy feather adapter. This one I have the Adafruit 128x64 OLED feather wing stacked on top. This one These components were purchased last...

I feel like this is going to end up being something simple that I'm missing, but I'm stumped. I have built 2 units that use Teensy 4.0. Each unit is supplied power from a wall adapter, so each Teensy has the VUSB pads cut. Unit A uses only the...

Please don't double-post. Use the other thread you started this morning.

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...

From a couple of CR2032 battery data sheets, it looks like they run 3.0V or less most of their life, but for a bit at the beginning. Dropping voltage shouldn't be needed. You could measure the current consumption using a good multimeter in...

Take a look at doing it with FIR filtering. The size of the FIR relates to the relative frequency width of the narrowest band in the equalizer. Traditional hardware and some DSP implementations used biquad or similar IIR filtering. The Teensy...

If your DAC update rate is not too high, there are lots of I2C options, too. Try googling "Adafruit DAC Qwiic". They have various breakout boards for 1-chan 12-bit, 4-chan 12-bit, 1-chan 16-bit, etc.

Thank you! Another question: I already have a code that should function with the Teensy 3.2 board. If I buy an Arduino Duo board, could I still use the same code (with a couple of appropriate adjustments) or should I completely rewrite the code?

I don't know if I am wasting my time by going down a long rabbit hole.... I am intrigued as to what the problem could be, and my curiosity is to investigate it, even though I have a work flow using the Teensy3.0 and FTDI module for serial...

You would probably want to use an SPI DAC in that case. There are many options at various bit depths (from 12 to 18 bits) , both single and multi-channel. Most are surface-mount, but a few through-hole DAC chips still exist.

Thanks! Let me know if you have any problems / questions with anything. Your xr-1 groovebox looks amazing and am enjoying the jams you've posted! I'll be following your progress. On a related note, I've been screwing around with FM as too. The...

Hello everyone, I'm new to teensy, but familiar with arduino and arduino IDE. For a side project I decided to give teensy a try. My first and major hurdle is I'm unable to read the analog input from the sensor(as5600). I'm attaching the pin data...

Thank you very much! I read that the I2S interface is designed especially for audio purposes, in my project I don’t do anything with sound. Do you have other options for me or would the I2S interface still work?

On a Teensy 3.2, pin A14 is the output of the onboard DAC. For a Teensy 4.x [which has no onboard DAC's], you could use the I2S interface to connect an external DAC of your choice. Paul

I power the RTC using a super capacitor, like this one: 1.5F 3.5v cap. I use a schottky diode between the Teensy's 3.3v output and the RTC power input to charge the cap. With a Teensy 3.2 it powers the RTC for several days. I haven't...

No.

Hi, I just read that the Teensy 4.0 does not have a build-in DAC function. Does the 4.1 version have one and which pin do I need to use for that?

Why without any info?) Teensy 4.1 (this was discussed) Arduino IDE 2.2.1 Last Teensy Core for Arduino IDE (TeensyDuino?) is 1.58.1 About code... I think about it. I think, it will be TFT_eSPI library with many fonts. I will try it and write.

I am very interested in one of those. I too have age related hearing problems.

Hi, I have a question regarding the Teensy 4.0. On the Teensy 3.2 there is a pin called A14 specially designed to connect to a DAC. The corresponding pin on the Teensy 4.0 is called On/Off, and I wonder whether it could still function as a pin to...

The stock latency with an unmodified audio library is about 6.4ms. That’s using the PJRC audio adaptor, as you are. The good news is that adding extra processing does not increase the latency, except in fairly unusual topologies which you...

I'm watching as well as I'm suffering this same issue. I power up my system once every week or four. CR2032 battery - a couple of months and I no longer have an accurate date and my data file naming goes bananas. :( Just ordered an external RTC...

KidChaos, Circuit below is driven off of the magneto P-lead. Running off of the low voltage side is safer - both for you and your Teensy. Put a scope on your kill switch or low voltage side somewhere (not sure what type of ignition you're...

Saksham... No doubt - Paul designed a pretty slick system. Your requirements are easy (so far). Teensy 4.1 ADC can measure from a few mV just above GND to a few mV below 3.3V (I can't remember the exact limit.) Won't burn out the chip unless you...

I've been using Linux since 0.98 in the fall of 1992 at 2400 Baud. So cool seeing what you are doing with it and the tricks to get it to do what you want - I guess it's not tricks - these all look like pretty awesome features that are way over my...

Hi All, I've just about finished up building a prototype bone conduction hearing-aid system. At the moment is consists of a pair of mics, mic pre-amps, 5 watt amplifier and bone conduction transducers. I have single-sided deafness and a hearing...

Without any info... here's a completely blind guess. Maybe you have Teensy 4.0 or 4.1, and maybe you also have it connected to other circuitry which has a separate power source, *and* maybe that separately powered circuitry drives one of...
