Activity Stream

Thanks for looking at this - sorry for the delay in response... Yes camera flash would generate signal through LSR - this voltage would be used to trigger a special recording - preferably with a different name to the...

Was Teensy selected in IDE for Board? Nothing DUE should be used or needed. TeensyDuino comes with an optimized ILI9341_t3.h driver that should be used. More details needed if there are issues after that . . ....

Hi Theremingenieur, I am still having trouble with I2C so have put that to one side for the moment and instead I am outputting the Resolver angle as an analogWrite. Then in the other teensy 3.5 card I am...

Much appreciate your patience getting me to see the missing (); I was looking for a difference in the number of lines of code and didn't focus on the character detail. So now the compile gets further but still doesn't...

OK, my last try -- in your post #2 your sketch says void loop() { ttransfer.transf } The actual library/github sketch says void loop() { ttransfer.transfer(); }

Yes, that's the same sketch. The way I copied it into my second message doesn't read as clearly as your boxed display. The spacing without indents maybe makes it look like lines are missing, but it's all there. I'll...

Paul - Really dumb question from the n00b (I'll try not to ask too many). I've installed the Arduino tools (1.8.5) and then the Teensy add ons (1.4.2). When I verify, I get compilation errors around each of the...

Legit! Thank You!

Hello, just to let you know: There is also an early version of a UAVCAN driver implementation which is based on collin80: https://github.com/tum-phoenix/drive_teensy_libuavcan

I don't know where you're getting that? here's what I see there /* TeensyTransfer Demo To make a USB RawHID device, use the Tools > USB Type menu */ #include <TeensyTransfer.h>

The fresh copy I got looks exactly the same. No additional lines. Am I getting the wrong copy? Ran again anyway, but still fails to compile because of: 'class TeensyTransfer' has no member named 'transf' This is...

Re: compile errors you somehow deleted some of the last lines in teensytransfertool.ino ??? Get a fresh copy in the IDE from File > Examples > TeensyTransfer > teensytransfertool And before compiling and loading...

Hm that's probably a smarter way to do it. This means that the device interacts with Windows only through this "driver." Now I just need to find a way to create this driver that sits on the system tray, intercepts the...

My guess, is there is a driver on the PC, that monitors the input from the tablet, probably either defines another device or special reports. I looked at one of their tablets, to make it at least partially work...

I have produced similar projects, where I want an internal sequencer running alongside midi input. Its not that difficult really. What you need to do is set up a global variable called something like TriggerNote, then...

nice project and great presentation. thanks for posting the info.

It's what I would expect. In front of the voltage regulator is a diode which adds an additional voltage drop (about 300 mV).

Only difficult is, when camera flash occurs during hibernate. for the time being, the hibernate mode switches all off and only restarts on RTC alarm. If one does not sleep as deep as hibernate, maybe system could be...

Thanks for this. I'm a complete newbie (well, I briefly used an Arduino 10 years ago at uni) and pondering putting together a controller for a SSL type EQ plugins. The way you've packaged together your thinking like...

Thanks! Lots of good stuff linked to in that thread. I must not have used the right search terms.

I have continued trying to isolate what's causing my communication error. Have now run teensytransfer on multiple Win10 PC's and many different USB ports and cables. Same error on all. Ordered another Teensy 3.2 to test...

Thank you very much. I will attempt to try out the things that you have stated above and I hopefully will get it to work.

Encoders only report steps from starting position which will be unknown so you cannot output an angle, hence the libraries only report steps. If you know the steps the conversion to angle is trivial - see below The...

This post breaks them out : forum.pjrc.com/ Teensy-Quick-Reference-Code-Examples-Tips-and-Tricks

you are right.. i found out, in german it's called "schmitt trigger" .. oO ..but it seems to be the pont @ where I can pick up the readings .. I got it wokring now :)) many thanks @all.

Problem solved. Wasnt the code, the library, Teensy 3.5 hardware or any of that. Was my frequency generator. For some reason, the output goes HI for a second or so when changing the frequency up, but not when...

Thank you for the advice. I was waiting for the Teensy 3.6 board and wanted to update after some testing. Unfortunately, it died not so long after receiving it !!!!! Teensy 3.6 board was sitting in the breadboard,...

Is the 3.8V measured under load or out of the circuit? What is the LiPo source/size/##? At 3.8V it isn't freshly charged. Is the drop the same when the cell is fresh?

I'm using the Teensy 3.6 for a battery powered data acquisition system. I'm having problems with the on board voltage regulator. The data sheet claims a voltage drop < 100mV when the current is around 100mA. The Teensy...

Now i think it's better, still missing the exhaust pipe and we done! #include <Audio.h> #include <Wire.h> #include <SPI.h> AudioSynthNoiseWhite noise1; //xy=696,304

I will be using this encoder: https://www.usdigital.com/products/encoders/incremental/rotary/kit/E5 It has 2048 individual demarcations, making one mark moved ~ .176 degrees. When looking through the two websites...

Hi forum (Paul, defragster), I have desoldered the additional resistor (see above). I also replaced the 470R resistor for MIDI-IN with a 220R resistor: same result: One T_3.6 works (the newer one), the other not...

Thanks Crees. If USB2 is 480 Mbps, why does Paul reference 12 Mbps above? Is that a restriction of the Teensy’s USB connection? Artnet and sACN are a bit of a mystery to me. Do you have any information on your...

Sorry yes I had timeout = 0 at the end in my main program, not quite sure why it didn't appear in my example above. Weird. Ill test this again tomorrow. Still strange though isnt it, how it works fine lowering freq...

I believe it’s the symbol for an inverting buffer, although I can’t remember if it’s strictly necessary or just best practice to use them for any midi transmitters such as MIDI THRU or OUT.

Maybe it's a power thing?? But you do need to add timeout = 0; after count2 = 0; to keep from overrunning the serial monitor and to properly manage your timeout. (I jumpered 5 and 6 to pin 23 and used tone(23,freq)...

I got miti OUT working now, but somehow I can't get Midi-IN working. what diode should I use here?

I just can't figure out what is going on here. Static frequency, its fine. Let the input sit and it reads it fine. Lower the frequency, its fine. Reduce the frequency and the output is smooth and works correctly....

what does this symbol stand for?

Looking at the data sheet it looks like the analog output does not normally rise above 3.3V so if you like to live dangerously you could plug it straight in and hope... Better answer is to put a 2/3 voltage divider...

Ill take a crap shot at this but if it was me I would be doing a little more effort on the regulator side. Granted you using a 3.3v regulator but what you need to be careful of is that this regulator becomes very hot...

It depends on the USB hub and hardware but most ports and hubs are USB 2 (480 Mbps) so it would be able to handle quite a few USB 1 devices at 12Mbps. Your limit will be on how well your software can detect and send to...

sure you can, it may only a little bit slower depending on implementation of memcpy

Ahhh. Nice. Thanks. Guess you don't need to worry much about them overheating as there's not much you can do about it! Sorry, don't know of any sites specifically crowd funding these sorts of projects, but guess...

When asking questions, it helps to provide links to the device you want to use. Is it this one? https://www.usdigital.com/products/encoders/incremental/rotary/kit/E2 And is there any reason why the default encoder...

Good evening, here I am with another update for IFCT. Filters now have an enhancement. for FIFO usage: When applying filters, first it's a good idea to REJECT_ALL frames from comming in. You may edit any of the 0-7...

Hi, and thanks again. your input helped to modify an existing library: https://forum.pjrc.com/threads/53122-DCF77-and-module-Which-library-is-working This actually works with "attachInterrupt() and millis() ". :-)...

Hi, I managed to solve the question: At http://thijs.elenbaas.net/2012/04/arduino-dcf77-radio-clock-receiver-library/ is a description of his library, which is also on: http://playground.arduino.cc/Code/DCF77 ...

Since you hit AudioMemoryUsageMax = 4 on the second screenshot, I'd up the allocation, since there's ample memory: // Always allocate memory for the audio shield! AudioMemory(8); Since you are also working...

I was having intermittent trouble with an i2c EEPROM on a breadboard a while back and the problem might be the hook-up wires that you are using. I have had several hookup wires fail on me for seemingly no reason,...

Hi WMXZ, thank you for your answer, I have been able to do what I needed! One question: instead of using memcpy: memcpy(out_block,&temp_buffer, AUDIO_BLOCK_SAMPLES*2); one can write this? for(j=0,...

Here is an example of what I mean, I've got to rewire the entire circuit - with this only being part of it, because I spent a bit of time on another project. This is directly after pasting code into the import dialogue...

Anybody out there?

Thanks Paul, that is great news! I wish I had discovered this info a while ago, but I obviously didn't ask the right questions. Now the big question is, can you plug a USB memory stick into the Teensy USB/serial...

Timer code would call note events that would both fire internal NoteOn events for envelop objects in the audio library and send MIDI. That is to say you fire the same code but the midi is not calling the internal code...

Yeah, OK it looks like you have exampleClass loaded from Object oriented can, unfortunately I don't mimic the Flexcan_Library class(s) at all, unless theres enough interest to do that then ill think about it, but the...

From your PC's perspective, it is as if you have this sort of device.

W5500.

cool thank you :)) maybe one more question.. what is this usbMIDI.getCable() "Virtual Cable" thing?

Have not had a chance to run up your rebuilt code yet, but suspect there is the exhaust note thing that becomes much more significant as the RPM reaches the point that individual exhaust pulses start to blend together....

Try sudo stty -F /dev/ttyACM0 raw -clocal

I put a multiply block between the sound created by the cylinders/blasts and a sine. The result is much better at low speed, I'm happy! Nevertheless the whole lack of realism at high speed. Did I forget Something?

What ethernet chip did you use? W5500?
