    getting compile error on code that was previously good before 1.52 code excerpt is small code to show error - ATOD i normally do is as shown except often inside a function that is called by an interval timer - the fix...

    found in my archives two documents - the previously mentioned IMXRT1060CEC.PDF and also IMXRT1060IEC.pdf basically identical at a glance. also sometime recently i described TLC hibernate current as 11-14 ua but that...

    just remade the msmnts - they are good. if you look in IMXRT1060CEC.PDF which is the technical datasheet 111 pages 1.9 megabyte on page 26 table 13 they list some of the idle mode currents and if you assume that on...

    please look three posts up for all of those currents. if you can stand a cold start every time, see the link two posts up. i have used the cold start method w rtc on T4 and average "sleep" current is 220 ua. if you...

    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...

    the fixes for T36 to do ADC setup also worked for T4. almost work for TLC. in the code below the disableDMA call was my feeble attemp at a fix - did not work. code below is an excerpt from larger code that does fft...

    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...

    the code below is a small excerpt from a program that compiled fine under 1.48 but not under 1.52 i am hoping i am doing something wrong and that it is not a problem with backward compat because there is a lot of...

    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...

    just installed td 1.52 over 1.48. had to delete the "utilities" folder in snooze lib when compiler said cannot use src and utility folder both - utility folder was i guess a leftover from 1.48 which did not get removed...

    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...
