Yes, no alternator involved. Yes, but as there is also a small fridge connected to it. It won't last to long :)

Thanks Paul, I didn't think of that. The result is the same, unfortunately.

As a first simple test, try setting Tools > CPU Speed to only 24 MHz, so it runs at a speed not too much faster than Arduino Mega.

Thanks for the explanation of how it should work.

Hi folks. First off, apologies for resurrecting an old thread like this, but I'm dealing with a very similar issue and cannot find much info out there. Some of this thread is pertinent. I'm trying to get a Noritake...

Would it be best to just attach the code files? Well never mind they are too big.

Most significant change looks like Arduino is updating the gcc toolchain to 5.4, exactly the same as we've been using on Teensy for quite some time. I don't see any use of its new features like constexpr constructors,...

Yeah - they have been around a long time but right now I am not using the libs. BTW: Finally am able to send and receive mavlink messages from qGrounControl. Just have an issue with the incoming packet contents. ...

What fun! Seeing any noteworthy changes that affect general Teensy Usage? Adding the parallel build yet or other things?

They're the same, as far as I know. The footprint on the bottom of the audio board has long pages which can accommodate the wider SOIC chips. As far as I know, this RAM chip only comes in the narrow body. But the...

The path to success involves making small steps and checking the results as you go, usually by printing stuff to the Arduino Serial Monitor. Getting a final formula that you can just copy & paste into Arduino have...

Please use a voltmeter to monitor the actual analog voltage right at the A4 pin.

Just to be clear, having 2 or more windows open is not necessarily multiple instances. You can use File > Open or File > Examples as many times as you like for lots of open windows, but they're all the same program...

what is strange.. the potentiometer only goes to 1023 if connected to Vin.. if conntected to 3.3V it only goes to 845

Try powering LM35 with 3.3v and get rid of INTERNAL ref and use 3.3 in calculation, and this sketch works for me float tempC; int pinLM35 = 15; // i have been using pin 15 for measurements void setup() { ...

Pin 31 is from Serial2, so it won't work if you're already using pin 10 for serial. Pin 31 would only be useful if you had to dedicate pin 10 for some other purpose (like if you were hypothetically using the audio...

Thanks a lot. I think you are rightband im just going to start from scratch and build from there. The readings im trying are inside a sketch with other oscillators and fm. Maybe im inducting noise or sone...

Best write performance requires using the mult-block write command in RU (Recording Unit) sized chunks. For large SD cards this is quite large. (RU is a multiple of 16KB) When I test write speed the way I do it is to...

I just feel that my approach is obviously not really helpful for you and I’m sorry for that. If the frequency is calculated correctly (as verified), but if the waveform object doesn’t take it, I’d dive into the audio...

Hi, hope i did not put you off with my comment. Just trying to explain my noobness regarding this matters. I have been checking the forum for answers regarding the frequency formula that i posted, but havent found...

Must be a concept or wiring problem/error. Please share detailed schematics/wiring diagram/pictures of your setup.

Hi guys, I have recieved some brand new slide-potentiometers today and just tried them out.. this is definetly not a pot-problem, still the same behaviour.. I tried it on a Teensy 3.2, too :( what else could cause...

IIRC it was a MAC - no known problems there with Dual - it should work - if not PRJC needs to know to correct it. There are two methods - the new Teensy_sermon and the existing IDE Sermon. If the new improved Teensy...

How much you know definitely affects how I would answer this. Are you aware that you have to compile the code for the specific Teensy for a USB type that includes MIDI. When you do the usb MIDI library is added...

I want to clarify my previous question. I frequently run 2 instances of the IDE to check examples but with a single Teensy connected. Would that still be a problem ? I am asking since I need to patch few system library...

Pin 31 is bottom side pad for Alt Serial2 Tx - see back of the T_3.2 card.

Yeah, I think so, too. I'm using a teensy 3.2 and the numbered pins in it's diagram only go up to 23 that I can see.

think for that he was refering usable pins on the 3.x series

No, it is correct the problem is with 2nd IDE - those words were in my history and head - but not typed in that note. At one point it seemed hitting compile - then starting Tsermon caused trouble but not seeing that...

I feel pretty silly, but I don't see a pin 31. In the diagram, I only see up to pin 23. Where is pin 31?

i see mavlink arduino libs use std::deque and malloc :P

Oh ok I didn't know this. Thanks.

Won't hurt, but Teensy attachInterrupt() was extended a few releases back to internally set pinMode to INPUT https://forum.pjrc.com/threads/40552-Teensyduino-1-32-Beta-2-Available?p=126657&viewfull=1#post126657

Yeah now that you mention it you did - sorry - I forgot. Any got it kind of working by asyncUDP for one and wifiUDP for the other port. I got qgroundcontrol at least reading heartbeat messages (gps and basic mavlink...

The Teensy 3.x's pins default to "disabled" instead of "input" unlike the AVR chips in the (Arduino UNO, Mega). In SETUP() add: pinMode(0, INPUT);

as forum rule at top states: Always post complete source code & details to reproduce any issue! (use CODE tags (#) when posting code to retain indentation) teensy3 pin interrupts are numbered by pin number like...

I used to be a huge Arduino fan, but once I found Teensys, that's all I use. Faster and more memory. Welcome to the club!

Sorry, meant to say 0Hz-20kHz here. 20Hz for the audible rate oscillator. Also I am using the beta, does the above issue relate to that possibly?

last time i seen a library define a pin thats unused it set -1 for its uint8_t value, although the library still used it regardless, and digitalWrites did nothing with value 255 but thats bad practice

https://forum.pjrc.com/threads/46793-Anyone-Doing-Pitch-Shifting

Hi Paul, I can't find the MKR1000 - it is probably knocking around at work somewhere. But the Due is working fine on both the Programming Port and the Native Port - I'm just running this (the equivalent doesn't work on...

you cant create more than one udp connection, its hard coded to one only, thats why whatever you do to one affects the other, they both technically link back to the same object at the source (ESP), due to the...

Hi Paul, Thank you for answering so quickly. I tested my code on a nano and I am moving it across to Teensy 3.2. I am using NOT_A_PIN for pins I do not wish to use but where libraries require a pin value but it isn't...

No, this is not an official Arduino name. It only exists on Arduino's older 8 bit boards, like Uno & Micro. None of their newer 32 bit boards like Arduino Zero, Due, MKR1000 support this. Please accept the...

I see, is it basically where you either have a seperate chip for USB comms (serial converter), or it is handled onboard the MCU (native)? I do indeed have a MKR1000 and a Due - I will test it out

Recent activity on github looks like the Arduino devs may be preparing to release 1.8.6.

Turns out there's a bug with WS2812Serial on pins 8 & 20. The other pins work fine. I posted a workaround on this thread just now. Maybe it'll solve the problem you're seeing? ...

Correct, more or less like that. The settings actually get changed, but when your code calls the EEPROM functions the FlexNVM gets configured back to EEPROM emulation. Then the first access to the FlexNVM is with all...

Has the problem ever happened with multiple Teensy boards, but only 1 instance of the Arduino IDE running? (and the hassle of having to repeatedly switch which board you're using in the menus) My understanding is...

There are 2 very different approaches used on these boards, which could be called native USB and serial converter USB. On Arduino Uno, there is a dedicated chip for the USB. When you Uno reboots, the USB connection...

Only if you use pins 8 or 20. Serial3 can only just barely manage the data rate. Serial1 and Serial2 are much more capable.

Ok. Here is another interesting case. If I create two Udp connections: //Teensquitto setup for UDP send and receive teensquitto Udp = teensquitto("WiFiUdp", &Serial1); teensquitto UdpS = teensquitto("WiFiUdp",...

Awesome thanks, Do you recommend setting the cpu speed to 120mhz for general Audio+Led use or just if I want to use pin 8? Also I'm using the IMU to control parameters like volume/frequency for my audio, but it's...

Ok, yes that's what I am experiencing - fair enough, I will just make considerations in my sketching - thank you!

The tone() function only supports output to a single pin at a time. You can get more with analogWriteFrequency() and analogWrite(). All the pins on the same timer get the same frequency, but the good news is Teensy...

Normally waiting once in setup until serial is ready on the Ubuntu side should solve the problem. Afterwards, the port should work at full speed. If it still doesn‘t, though, there is for sure a problem in Ubuntu‘s...

WS2812Serial is the best choice. Looks like there's a bug with pins 8 and 20. The simplest solution would be the use pin 1, 5, 10 or 31. If you really want to use pin 8, copy this file to the WS2812Serial...

Hey So i figured out why the WS2812 Library wasn't working, kinda. I moved the leds to pin 1 instead of 8 and it worked. However I don't know why pin 8 wasn't working, it says it's a supported pin in the readme...

So how do I alleviate that? The serial port is behaving very poorly in this case. The only thing I can think of at the moment is doing something like using a jumper wire to enable serial - or adding lots of...

Morning. Not really trying to do loop on the ESP. I will try to explain, may get long winded so forgive me. Oh by the way - don't think its a core problem on the overload: In teensquitto.h you have for read:...

Is this generating the audio from various oscillators/instruments or is it playing pre recorded clips? If you are synthesizing it is relatively straight forward to step things up or down but if you are playing...

Thank's oddson! That's awesome! You mean I can just call: usbMIDI.sendControlChange(control, value, channel); and it will work? Sounds to easy to me, but hey, what I know?! I thought I would need to include...

But the OP does say 'The circuit is completly seperated from the cars electronics', which would infer that it is not charged by the altenator, in which case I guess the supply would be pretty clean. That battery is a...

AFAIK, Anti aliasing filters have to be analog before the ADC and not digital filters after the ADC as CIC filters are.

If it is indeed sigma delta followed by CIC digital filter, then no steep AAF is needed, only the typical single pole LP filter at the input of the ADC.

The CIC filter is a special case of a FIR filter, thus no contradiction. And if it’s clocked with something proportional to the word clock, it would automatically adapt to the sample rate and thus to the input...

Paul, thanks for your test results, they are pretty convincing for 44.1ksps sample rate. To be honest, I did not check or test that systematically for higher sample rates. You are probably right that one would have...

loopback on the same ESP chip is not possible just so i understand, asyncudp receives, core’s udp version doesnt? if you change incommingPacket to uint8_t you wpnt need to cast it, dunno why the ESP core decided...

So far only Windows 10 and multi Teensy has shown trouble AFAIK. Don't hesitate to use it and prove it works well for you.

I do exactly that on T3.5, but in my case I compile for 24MHz and dynamically switch to 48MHz depending on the load. At minimum it requires a change to F_CPU via SIM_CLKDIV1 and millis() counter via SYST_RVR. But you...

Quick question - for those of us that connect only one Teensy at a time (although of different types) does the issue above have any consequences ? Platforms - Windows 10, Mac, Linux.

Ok - new problem - can't get WiFiUdp working. I used the code from https://github.com/esp8266/Arduino/blob/master/doc/esp8266wifi/udp-examples.rst and loaded directly on the feather board and it worked no issues. So I...

Hi Manuel, yes, that would work (but the footprint of the MINI54TAN would not be the same, so you cannot swap this out without a board change). I already have asked prjc for SWD support, and I know others had asked the...

Actually, maybe we don't need to introduce any. USB is host-driven and performs polling on rate like 100Hz. So, keyboard would send the same information every 10ms. This could hide all timing side channels that are...

Seems like a ridiculous thing to have to connect jitter (don't spend much time with) to isadora (very very familiar with) but need to network video between computers for a project involving multiple kinect cameras etc....

Hi! Many thanks for your reply! Im 41 years old, work 8 hours a day and have two kids. A year old girly and a 5 five year old boy. Yes, back then i should have studied what i really wanted by life has its...

It’s a possibility that the newer Teensy requests more power than the older one, just a theory. As a result, the power requirement is much greater than the camera connection kit can provide on its own, therefore it...

Ok - I give up. I been at this one all day with no luck on solution which I am sure you know. I am using AsyncUDP to listen for new packets and that seems to be working. But I need to send messages through the...

The Arduino Uno is ways slower than the Teensy and thus it is normal to hang up the serial communication when a much quicker Teensy starts sending data before the computer‘s serial port is ready.
