    Zapta,

    I did just finish a T4 translation of the ADC library. It's not polished, but it works. I put up a thread about it, I hope you can find it useful

    T4 ADC Library V0

    There is more work to be done, but it seems to be functional, so I figured I would release what I have so far.

    These files are a transcription of Pedvide's ADC library to the T4. My goal was to...

    Yes, sorry reading too quick.
    I believe my concern still stands however. As far as I understand the ADC, the continuous conversion setting of the ADC will raise the ISR on every conversion...

    You can use the analog read function. I have not tried to see how fast they are yet, It might be able to handle 10K samples without any problem. That isn't too high for a teensy. Actually reading...

    Last time I downloaded teensyduino the ADC library had not been ported to the T4

    Faster Data Logging over USB

    I have been fumbling around with using Pevide's ADC library over USB for a while now and I thought I would share my efforts. Attached are files that allow for fast data-logging over USB, I call it...

    If you stick to one ADC then absolutely it will be limited across all pins. You can lower the resolution to get more samples per second I think the continuous read sample that comes with teensyduino...

    cfmakeraw did not fix the issue so I ordered a new 3.6 and a 3.2 to test out. Failed on both the new ones.

    I switched from my laptop to an older win7 desktop that I built a few years ago. I am...

    Jacob.Schultz,

    I have a quick question for you, when you try my code, does your data make sense? I haven't gotten back to my c++ code yet, but I reinstalled arduino and teensyduino to make sure I...

    I've played with this a little more, still can't pin down my problem. My latest attempt was using Serial.write as opposed to Serial.println and using C++ to capture the data instead of python or...

    Well, I've played a bit more with my code. Python was definitely part of the problem. I switched to the linux shell command: cat /dev/ttyACM0 > logFile.txt

    Yeah, definitely need to try the new circular buffer code, and maybe rewrite my logging in C++. I made sure my ADC priority was set to 30 as Jacob.Schultz said, but I'm still stuck at 295K Rx for...

    Thanks for the replies. I did forget to state that I did indeed up the ringbuffer size, it was sitting at a ridiculous 32768, so I dropped it back down to 128 (need to remember what I changed when...

    Fast Data Logging over USB

    I've recently started playing with the Teensy 3.6 and Arduino IDE configured as a 'USB Serial' device at 180MHz, optimized 'Faster'. I am trying to put together a Time of Flight acoustic measuring...
