    Understood, and I can see how it would be tough to debug without context. It's good to know they do work. I have removed the code for cli & sei from my project, but the above was basically the meat of it. to get...

    well, I have some VL53L1X Lidar rangefinders that all have the same I2C address. =) also the Teensy I2C library has been a bit problematic so far, but I haven't spent much time on it trying to work around the...

    Also anyone have any experience with the Teensy and the Adafruit TCA9548A 1-to-8 I2C Multiplexer Breakout? they don't seem to be compatible at all, but it works fine with Arduino.

    Interrupts: near as I can tell this doesn't work, actually hangs the T3.6 when I call cli(); "The simplest and most common approach is to simply disable the global interrupt setting with cli() and reenable with with...

    the Basic Master example compiles fine, even when I change the port: Wire2.begin(I2C_MASTER, 0x00, I2C_PINS_3_4, I2C_PULLUP_EXT, 400000); must be something to do with the VL53L1X library, I guess, that causing...

    trying to use the updated i2c_t3 library instead of Arduino wire.h, so far not much luck: Arduino: 1.8.9 (Linux), TD: 1.46, Board: "Teensy 3.6, Serial, 180 MHz, Faster, US English" ...

    ok, I found what works is a slight variation of that: pinmode(shutDownPinRC, INPUT); the PIN_D7, etc., syntax errors out during compilation. I'm using tduino 1.46 and arduino 1.89, targeting T3.6. ...

    for a sec I thot I'd found my answer.... https://www.pjrc.com/teensy/td_digital.html but this errors out and won't compile. Doesn't like this at all: PIN_A5, etc. I can use outputs just like an Arduino, no...

    Q: this ain't workin: #define shutDownPinRC 33 // for RC switch this always returns zero: digitalRead(shutDownPinRC); I can measure the pin voltage with a DMM, I can see it go high (3.3 V) or low (0 V).

    I've had generally good luck, but a couple libs here and there won't compile, like Pixy2 (pixy is ok), or PFC8574T I2C LCD interface. Qs: 1. for INT, do I need to do this? seems to be working, but not needed for...

    howdy all! I'm new to the Teensy, but I've used a few flavors of Arduino for about 3.5 years now. I've noticed there are some differences. =) what would be really helpful (and I haven't found yet) is a web...
