    Hello All,
    Going through this now..... using Teensy 3.2 soldered on to a carrier PCB. Got here through: https://www.pjrc.com/store/ic_mkl02.html

    Thanks for the suggestions all..... will poke at them a bit. ;-)
  3. Compiler between Arduino and Visual Studio for Teensy?

    Hello All,
    Does anyone have a recommendation for an IDE/compiler that's a step-up from Arduino, but not necessarily as complex as Visual Studio?
    Thank You,
    -John

    Thumbs up! Fellow EE here too..... Fortran and punch card era. I've seen a few posts by folks just getting started that sort of lead me to the instrumentation issues.

    In any event, glad...

    LIDARLite library and i2c_t3

    Hello All,
    I've had a bit of trouble switching addresses on the Garmin LIDARLite. It's reading distances marvelously, but to use two on a single I2C bus, thus far making i2c_t3's wire calls has...

    Sorry Pete, it's just part of a much larger program not really meant to post as 'compiler ready'. The defines for UNIT_ID_HIGH, etc, are indeed insluded in a .h file, I just kept a commented out...

    Completed (?) source for moving LidarLite to new I2C address

    Hello again All,
    More on switching Garmin LIDAR Lite I2C address... needed if you want to share two on a single I2C bus.

    I'm going to work on the assumption that the "High:48 Low:128" bytes...

    I posted a thread this a.m. with a teensy bit of error checking which I'm trying to make a bit more elegant. Some I2C functions return an 'ack', and I'm mentally wrestling with how deep to go...

    LIDAR Lite address move

    Good Morning All!

    I'm getting two LIDAR's (Garmin Lidar Lite V3 (not HP)) together running from one Teensy 3.2. Had this working once a year back, but am having an issue getting back to where it...

    Elbarfo, the noise you may be just seeing could be artifacts of where your scope ground is referenced, how good the common mode rejection of the probe is, and that sort of 'instrumentation' issue. ...

    If the I2C running freely when the motor is running, but 'isolated', it's an indication of the "power supply topology / bypass caps" issue. If you put a resistive load, or an opto-coupler on the...

    Can't quite make out the horizontal us/div scale, but that's OK. The 1000 uF cap is way out at the end of the power distribution chain. I'd put it closer to the Garmin, right near the slip rings. ...

    "I2C dies" jumps out at me..... do waveforms go to heck? Perhaps you're running the I2C too fast for the pullups you have? With my particular prototype, I got as high as I2C_RATE_1000, which I...
  16. Hello Elbarfo, Is it just the PWM output...

    Hello Elbarfo,

    Is it just the PWM output alone, or the PWM output when the motor is connected? I saw a post where the 680 uF cap on the LIDAR was omitted or wired poorly and caused I2C issues. ...

    Duh! Slapping myself upside the head. You're right. wire.h is included in LIDARLite_v3HP.cpp
    I'm wondering how to get LIDARLite_v3HP.cpp to recompile with i2c_t3.h included? I'm not finding...

    It can't be long now....... ;-) But perhaps what I'm doing wrong is more fundamental. Should I be able to include i2c_t3.h instead of wire.h and compile? I went back to basics, blink.ino,...

    One Drive bug fixed?

    First post here.....

    A feature in 1.4.3 that might be nice is to possibly allow it to install with the nightly arduino releases. Or not. ;-)
