He is trying to experiment with NOISE CANCELLING. Broadcasting an inverted signal in an attempt to cancel out ambient noise. Due to the inevitable processing delay, will not work by playing output through a speaker to...

Just thought I would add a different graph of your (JotaEfe13) data.

Are you going to be selling them? I would be interested.

It could be to bring it in line with Serial ports where Serial (aka Serial0) is USB Serial and Serial1,2,2...etc are real serial ports. Not making a definitive answer, just surmising. Happy Christmas everyone, and...

That's the way Teensy 4.0 works in DeepSleep at the moment. I don't know if it will change in the future.

You could use MyUs.com to ship to the UK. They will set up a US address for you. Have stuff sent there and they will forward it to the UK. I have just set up a MyUS.com account for myself. The basic account is FREE. I...

OK thanks. I had not seen any post announcing that change.

£18 from Pimoroni, admittedly with £2.99 p&p.

You can use the code below #if defined(__IMXRT1062__) //Teensy 4.0 Code Here #elif defined(__MK66FX1M0__) //Teensy 3.6 Code Here #elif defined(__MK64FX512__) //Teensy 3.5 Code Here #elif defined(__MK20DX256__)...

Searching the web I found the following entry from 2014. Images provided at the arduino forum for this post look like your board. Perhaps this will give you a starting point.

One of these might solve your battery problem. Battery powered by 18650 cell, outputs 5v and 3.3v. Use the 5v and power the teensy as well, or 3.3v to teensy and 5v to ADC.

Yes, I have just ordered a 4.1 with pins, Ethernet Kit and PSRAM for £34.19 inc. 1st class postage. Pi Hut have just reduced the 4.1 to £26 from £26.50 (inc. headers for soldering). I expect to receive it tomorrow....

I am surprised you say that DigiKey is cheaper. I just took a look and including header strips The PiHut are selling the 4.1 for £26.50. Digikey are charging £29.36 inc. headers and £27.06 without.

No I don't have a link but you could look at Paul's posts. Just click on his name and select posts or whatever it is listed as.

That information came from Paul on this Forum. The power needs to come up in a controlled manner. This is accomplished when powered by 5v but not 3.3v. Paul suggested having vbat supplied with voltage before 3.3v is up...

I'll bear that in mind.

Here is the code, below. I will put a snapshot of the results for T4. The resolution of my capture device is only 41.66666ns. So when you see pin to pin times doubling from 42ns to 83ns it is down at the resolution of...

Hi Duff, have you any comment upon the Snooze wake up times I have found. See here.

No problem. I was hoping they would supply UK/EU at a decent postage rate like OSH.

If you power teensy 4.0 from 3.3v only, then it is quite likely that it will NOT power up. Supplying VBAT with a backup battery may allow the Teensy to wake up when 3.3v used to power it.

They are currently set up for US customers only. Bottom of his first post.

Does that mean there will be affordable postage to the UK as well? OSH only charge a $1 and put them in an envelope/jiffy bag.

Having looked through the code for the ElectronicsHub tutorial there in no reason why you could not change the ESP8255 for a HardWired Teensy ethernet system. Sending the email from Teensy would be similar to using an...

I think using two computer boards is a bit over the top. Since the ESP8266 has the WiFi capability and the ability to read a temperature sensor, there is, unfortunately, no need for the Teensy. There is a WebSite...

If you are worried about power failure why not use one of these with an 18650 battery to power your teensy. Keep it (the battery) powered all the time and should the power fail, with a 3000mAH battery for backup, you...
