    Pure Data to Teensy C++ Code

    I'm wondering if anyone on the forum has experience converting Pure Data code to C++. I'm not a Pure Data user, but have been using MaxMSP, which was also created by Miller Puckette, and is quite similar to pd, though now far more extensive (MaxMSP and its company Cycling 74, which some years...

    Learning the Peripheral Register Programming Model of the Teensy 4.1

    You move fast, Steve_AU! Pleased to hear that you will be checking out the evaluation board. I look forward to hearing more about your experience with the setup, and hope you find it helpful. I agree that these devices in the current 600MHz+ range are quite impressive. Like you, I have a very...

    Learning the Peripheral Register Programming Model of the Teensy 4.1

    If you're working with the IMXRT1062 at this level, you might want to consider purchasing an NXP development kit and setting up the MCUXpresso environment for checking it out. It's not a Teensy with Teensyduino of course. But it's a powerful way to become familiar with the chip and its features...

    Enabling/Disabling USB Audio at runtime

    You can simply disconnect or reconnect the patch cords to the USB output object, as is done in the following code fragments for an I2S input object: // I2S Signal In AudioInputI2S audioLineIn; . . . // setEnabled // // Enable/disable module's LR input signals // void...

    W25Q256 breakout for Teensy 4.1

    Yes, that all makes sense, and is basically what I imagined. One final follow up, though. Can you describe the conditions in which you were able to test SerialFlash with some of the large non-VSOP package devices? If one needs to build a PCB to host the large NOR devices, I'm open to that...

    W25Q256 breakout for Teensy 4.1

    Thanks for the response. I was aware that SerialFlash only works with NOR, but I seemed to recall (perhaps incorrectly) that there had been some discussion about extending support to NAND. However, what I'm most interested in is having access to a larger flash device (512Mb or 1Gb) for playback...

    W25Q256 breakout for Teensy 4.1

    It's been some time since this discussion was active, but in the intervening time, I wonder if anyone has made any progress toward audio support via SerialFlash (or some equivalent) using larger Flash NAND chips. I have a Teensy 4.1 with a 256Mb Winbond W25N02KVZEIR QSPI Flash chip. It can be...

    Teensy 4.1 Proto System USB Host Problems

    When, per your suggestion, I measured again with the Teensy removed from the board, no power, all other ins/outs disconnected, I got these results: Teensy Alone Out of circuit ------------------------------ D- <> Gnd 2.19 M Ohms D+ <> Gnd 2.17 M Ohms Board Without Teensy...

    Teensy 4.1 Proto System USB Host Problems

    It seems that the readings on the Teensy, when removed from the baseboard, are OK, as indicated in my last post; but I will check again to be sure. I haven't yet checked the baseboard connections with Teensy removed, but I will let you know what I find.

    Teensy 4.1 Proto System USB Host Problems

    All the pins of the USBHost header on the T4.1 appear well-soldered, top and bottom, as to all the pins on the USBHost connector on the board. As for the T4.1 pins to Gnd resistance, I measure: Out of circuit -------------- D+ <> Gnd 1.4 M Ohms D- <> Gnd 1.4 M Ohms In Circuit ---------- D+...

    Teensy 3.2 Problem with Powered USB Hub

    I have a mystery regarding which I hope some other Teensy users may be able to supply some clues or insights. I have the following devices: iMac Computer 4 Teensy 3.2 modules, which I will refer to as TeensyA, TeensyB, TeensyC, and TeensyD, all programmed with the blink example app. Anker...
