    Teensy + Ethernet + 3 RFID

    Hi, I tried with the WIZ850io module and reducing the cable length with some results but the same problem. Now the device tekes the correct IP but after the initialization of the RFID it change it to 10.0.2.160. I tied also to invert the setup of RFIDs and Ethernet with no results. Can someone...

    Teensy + Ethernet + 3 RFID

    Hi! I'm working on a project that use a Teesny 3.2, 3 RFID MFRC522 and the WIZ820io module with the adaptor (waiting for the WIZ850io module to test). I need to read the value from the three RFID and comunicate if each one is reading the correct one or another one. The communication is in...

    AudioInputAnalog and analogRead

    Hi, I'm using use the audio library without the Audio Board, to analyze a signal from a Electret Max 4466 from Adafruit, correctly modified and connected. It works correctly but now I need to add to my project an IR sensor, the Sharp GP2Y0E02A. As i read everywhere i cannot use the analogRead()...

    Watchdog on Teensy LC

    Thanks Paul, it's all really clear. I'll try to improve my software to avoid the use of watchdogs!

    Watchdog on Teensy LC

    I understood my mistake. The BasicUsage example doesn't work with Teensy LC simply because in that sketch there are some delays greater than 1024 msec. avoiding that delays it works. In some sketches I need a delay and for this I used this code, to avoid the watchdog time out: void...

    Watchdog on Teensy LC

    Thanks it will be very useful Unfortunately in my project I need to use both Arduino, Teensy 3.2 and Teensy LC and I'm writing a library that manage all of them. For this reason the SleepyDog library would have been useful, I will try to modify it also for LC.

    Watchdog on Teensy LC

    oh, I found a solution there https://forum.pjrc.com/threads/30567-Hardware-reset-on-Teensy-LC I understand that is it impossible to increase the time to service the COP, but it means that I cannot use a delay greater than 1sec if I use this watchdog on Teensy LC? Thanks Luca

    Ethernet library server.available() problem

    i connect PC and Teensy on a switch connected to my router where I assign the private static IP's. Unfortunately is not my site and the user manual is not so good. It is the first voice of the menu. I understand that it's not so easy to make some tests, I hoped there was some known problem I...

    Ethernet library server.available() problem

    You are right, sorry. In the Room Management page you can create an event (or use the one that I had created) specifing the IP. If you give me the right IP I set it for you. Thanks Luca

    Ethernet library server.available() problem

    Hi, I'm sorry for this huge post but I need to explain it clearly. I'm working on the realization of an Escape Room. I would use Teensy as controller of each game, connected via Ethernet to a PC. After the first trial I found some problem with the communication with the software due by the...

    Problems with Interrupt on digital pin 0,1 and 13

    Thanks all, I write down mine Bounce function but I will try this one. I found the problem with the interrupt pins. Easily, the board is broken and that three pins doesn't work. It remains the problem with pin 13 on Teensy LC but I will not use it for this project. Now with the interrupts...

    Problems with Interrupt on digital pin 0,1 and 13

    Ops! I'm so sorry, I realize that I'm using a Teensy LC instead a 3.2 In the LC the pin 0 an 1 doesn't have interrupt capability, but the 13 yes and it doesn't work. I replaced the LC with a 3.2 and now the pin that isn't working are 3, 7 and 8 As before using the serial monitor I verify that...

    Problems with Interrupt on digital pin 0,1 and 13

    The button is normally open and it works with all the other pins in that configuration. The ones that gives problems are 0, 1 and 13. I don't think is an hardware problem, and I tried to visualize from Serial if it recognize the pressure of that button. Phisically it does, but the interrupts...

    Problems with Interrupt on digital pin 0,1 and 13

    Thanks Kurte for the reply Pin 0 and 1 as the others has a pulldown resistor and are connected to the switch. The other pin of the switch are connected to 3,3V I attach a picture of my simple circuit. What kind of problem can the Other LED gives? Thanks!

    Problems with Interrupt on digital pin 0,1 and 13

    Hi! I'm working on a project in which I have to use 10 led buttons and a Teensy 3.2 I have to recognize when 5 of them (and only that five) are pressed. The right configuration opens an electromagnet (by a relè). At the same time I have to send a message trough Ethernet when the configuration is...

    Change sample rate for Audio Adaptor Board for Teensy 3.0 & 3.1 FFT

    I think you inverted the name of the file. I changed the files but the results is the semo, 43Hz of bin width How did you test the software? I use the fft example with a mic and produce a 430Hz freq, that results in the 11th bin...

    Hi, I used the dacVolumeRamp(). The click problem seem to be resolved, and the noise at low level is reduced (but not resolved). I will try to change my woofer!

    Thanks for the hint, but it doesn't work. There is no significative change. I will try to modify again some parameters.

    I modified the AudioMemoryUsageMax() with no results. I still have these problems.. After all the other tests (even some example), i have that click when i clap in the mic and a scratch to volume variation. Suggestions?

    Repetitive click

    In these days I tried more my software. I excluded three sinusoids, using only the 8 HZ sine, and I excluded the relative mixer gains. In these way i can perceive a scratching noise, as before not related to the volume of the audio input but lower than before. I notice that this noise is...

    Hi! I have a little problem with my software. I use Teensy 3.1 and audio board, acquiring the audio signal from a condenser Mic and a. From the main out of this one I go in the Line input of the audio board, trough a jack, connecting the 3 wires ( + - and GND). I compute an FFT and i sum the...

    Change sample rate for Audio Adaptor Board for Teensy 3.0 & 3.1 FFT

    here it's my mistake! This is very helpful and interesting, I will use someone of this methods it to improve my software. But now, for my project the fundamental is not so important i need some armonics and I think that FFT is still the best solution. I don't need a fast computation, probably...

    Change sample rate for Audio Adaptor Board for Teensy 3.0 & 3.1 FFT

    ok, but my real problem is to obtain a better resolution on the low frequency. In this case 21Hz of bin width is too big In the range from 200 and 500 Hz some tone differs from the others of 13Hz and I cannot directly recognize it, cause it falls in more then one bin. Surely I can check for...

    Change sample rate for Audio Adaptor Board for Teensy 3.0 & 3.1 FFT

    Ok.. I've tried in the afternoon, and nothing change. I've modified the AUDIO_SAMPLE_RATE variable and the CPU SPEED without results. I could try to decimate the audio sample after the sampling. I know that it a waste of computing but I can't see another solution.. I will try to modify the...

    Change sample rate for Audio Adaptor Board for Teensy 3.0 & 3.1 FFT

    Hi, I'm working on the Audio Adaptor Board for Teensy 3.1 using the FFT example of the Audio Library, to perform a frequency analysis of an handmade Kantele . I'm trying to detect every single tone of this instrument, trought an 1024 FFT in the range of 40/4000 Hz. The example works great but my...

    Teensy3.0/3.1 Audio Library Perform FFT on analoginput pin without Audio Shield

    hello, I'm also working on the same solution discussed by kian79 on a Teensy 3.1, and I tried to set a different size of FFT in the adafruit sketch. Strangely if I set the FFT_SIZE on 512, I cannot read the serial. If I set it on 1024, the sketch works even if not as fluid as the original, but...

I connected a capsule electret microphone (one pin on MIC and...
