    I am currently working on a project where I have two encoders connected to my Teensy 4.1. As of right now I am only focusing on one but if I am not mistaken using this library to sample the pin of the second shouldn't be an issue as there are...

    Look into IntervalTimer. You can have more than one and can get very good resolution.

    sRGB565 replied to the thread Game Console with iMXRT1062.
    This is a really good idea. I had originally thought of making a test batch of boards but discarded it due to a lack of necessity prior. The bus interconnects are all point to point in a kind of star topology. These aren't the main source of...

    You asked for it! I've attached a zip file with the tracklogger6 sketch. This a few revisions back and uses the Sparkfun UBlox GNSS library. I started programming embedded systems about 50 years ago and have avoided using dynamic variables...

    3 bytes times 1280 times 720 is 2.64 MB so two of those buffers fit easily in 32MB single SDRAM/VRAM as on the DevBoard design. That leaves 26.7 MB free from the 32MB - enough room for larger display or 10 more such buffers? Noted on other...

    Just use default i2c driver with the BME28, i.e., Wire, instead of the i2c_t3 library. Use the Example 1 directly. Cant help more since you didn't post your sketch. /* Get basic environmental readings from the BME280 By: Nathan Seidle...

    The problem is that another library in the project uses i2c_t3.h, and using the sensor library (which uses wire.h) creates the conflicts that I pasted in the first post

    Sparkfun ship the ZED-F9P with the ANN-MB-00 GNSS multiband antenna but u-blox also sell the ANN-MB1-00 antenna with extra coverage of the L5 band (but no L2) for same price. According to Google Gemini (I hear you groaning :cool: ) the MB1...

    I don't recall any corrosion problems with SD cards in oceanographic loggers in about 100 logger years of deployment over 50 or more loggers. We did take precautions: 1. The loggers are in watertight cases (Well DOH! they're deployed 10 to...

    @Remi_Music Thank you for your response, but I am not looking into building a Midi controller I want to play the audio from the Teensy and manipulate it. I have source code for this on the STM32F746, and I know it has been done on an STM32F103...

    That sonnds like what i need, Like i said in my post, when i unplug the teensy, from the computer, the solenoid shuts off and restarts , i am not a code creator, any guidance on how to do this would be helpful. thank you so much.

    That posted sketch is BLANK? With Serial4.begin( ??? ) at the right baud rate then pins 16 and 17 are correct if Rx on one goes to Tx and also Tx goes to Rx. GND must also be connected, and the device must be getting enough POWER to run. Are...

    defragster replied to the thread watchdog Timer for teensy 4.1.
    Interesting how this happens? Is the NoteOff missed or somehow lost? Or is there something latching the pin ON when it was commanded to drop to OFF? Watchdog is critical when the sketch can HANG somehow. Not sure there is a hang of any sort...

    jmarsh replied to the thread Joystick mode problems Teensy 4.0.
    That pinMode call is for pin 0 (one of the button pins), not analog pin 0 (which is pin 14). Teensyduino 1.59 will automatically disable the pin keeper anyway for analog reads.

    Hardware-wise, using the MKL02 chip from PJRC means you're good to go. Software-wise, most libraries are MIT license which is meant to allow usage in commercial proprietary products. But a few are GPL, like Entropy, so check the license on all...
  • BriComp
    Of course. This line in setup pinMode(0, INPUT_PULLUP); causes that. INPUT_PULLUP tells the Teensy to initialise itself with a pull up to 3V. Hence if no connection you get 1023/1024. That is configuring the input as a digital input. For an...

    How exactly do you connect your potentiometer? It should have three pins: the one in the middle has to be connected to the analog input pin of the teensy. The other potentiometer pins: one to ground, the other to 3V.
