    ADC problem TD 1.52 with TLC is resolved kind of, KurtE - i took your advice and tried to fix AnalogBufferDMA.cpp, commented out line 163 which is in a TLC only if. just for completeness tested back again to T36 and T4...

    thanks for all of the feedback KurtE and Silverlock. looked at github - none of the files have changed for 2 months but i do not know how that might relate to the freeze date for 1.52. not sure what "raise an issue...

    Silverlock, that did it - i had looked thru the documentation and lib files but overlooked that - amateur programmer who does not know CPP - only C - so i think whenever i see -> or : or :: my brain goes into a very...

    Is that to say that hib only wakes with a reset and not any timers? I can measure the hib current. Good luck w home automation.

    here is more data for T4 sleep all done w 5.0 volts, TD 1.52, ARD 1.8.5, WIN7pro64, TEENSY 4.0, currents are during snooze, currents seem independent of clock speed ---rtc--deepsleep= 9.8 ma---sleep=19.6 ma...

    thank you defragster - used sleep and found the real problem was mine. Both (sytem idle) sleep and deepsleep work just fine with just +5 and ground. I get the dumb*** of the day award - the usb to bench supply...

    Frank B - I am chomping at the bit to play with Duff's snooze lib included in 1.52 for Teensy 4. Do you think that the serial monitor is so broken that someone with only medium Teensy experience (2.5 year) and medium...

    XFer has a oood point - there is a lot to like with TeensyLC. I like the really low hibernate current - 11-12 ua compared to T35 at 53ua and T36 60 ua. Also, I have found that TeensyLC can get quite a bit done for $12...
