    Hallo, I'm using Teensy4.0 and ublox NEO-6M i tried using TinyGPS Library (simple_test.ino) Example and changed the Serial to UART Serial exactly Serial4(pins 16 und 17) but i got this message i made sure that I checked my wiring but there...

    Perhaps this is a better approach to use a USB stich on the Teensy 4.1 USB host.... are there any example programs for testing. I looked a bit arround but not find a lot of info. I like to log on the USB stick as example temperature and pressure...

    Currently due to the severe lack of advanced PCB design, we're going to use existing x64 boards (i.e. old laptops) for a testbed for a while. We will continue with this project but currently we need resources that we just cannot acquire at this...

    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...

    Impressive work! Some questions and ideas come to my mind: Why use WS2811 LEDs? Do you really need all the colors? If not, there should be LED options which are more energy efficient, i.e. give you more brightness drawing less current. WS2811...

    Thanks Tom, These LEDs have a single replacement capability, which in our line of work is priceless. The APA102s take too much skill for the average Joe to replace/solder. Over the years a lot of designs have been tried and they all have their...

    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.

    Was the MKL chip purchased brand new? Not taken from a different board?
  • B
    Can you measure the VDD_SOC_IN voltage? If the last stage of the power up sequence is working, it should be 1.15V or 1.25V. Maybe also check the voltages on VDD_HIGH_CAP, NVCC_PLL, and VDD_SNVS_CAP. If the board truly has completed all stages...
  • B
    Another thing to check, probably a long-shot, is whether you have anything driving the IMXRT1062 pins before it starts the power up sequence. Perhaps other devices that power up separately?
  • B
    Does this mean the 1062 wasn't fuse configured and updated? Would the 15 Sec Restore complete this? @bhaskar was this tried?

    Hi Paul, Many thanks for the reply. We fixed the issue by simple resoldering the MKL and W25 chips. Apart from that the oscillator connection was wrong. Now we can flash codes without any issue, and IO ports seem working fine. We will do more...

    Hi everyone, Thanks for the valuable insights. The issue was perhaps improper soldering as I do not have much experience. I removed and resoldered both the MKL and W25Q64 chips, and it now works as expected! The main mistake in the design was...

    You could use a capacitor to drive the solenoid. Charge the solenoid through a resistor (gives just enough current to hold solenoid in place). Then when you fire the drum stick the initial drive current comes from the capacitor, followed by a...

    WMXZ replied to the thread U4 power IC.
    The schematic is consistent with the pictures of U4 showing 6-pin. I guess the first question is where and when did you buy Teensy4.1 and maybe you can post a picture?

    @mjs513 @KurtE have you tried hooking up two displays to one FlexIO port on different CS pins? I would be VERY interested to see how that works and what performance can be achieved.
