Too bad i didn't stumble on this thread while trying to have my Teensy LC's comparator work. I eventually found the SIM_SCGC4 bit to set to bring CMP to life, but it did take a couple of hours of...

Hi,
I think I ran into a similar issue with IntervalTimer on Teensy LC and to some extent 3.2 too.

The setup is very basic : a led on pin0 and ground, another led on pin1 and ground, and some...

I wrote a quick account of some tests I ran yesterday about how...

I did read about the ADC clock, and indeed planned on using those ADC_ADAC* speeds.

If I understand Freescale's recommandation properly, the idea is to bring the MCU to a "complete" stop while the...

Hi,

I'm trying to get the most of a teensy LC ADC, and reading the datasheet :

31.6.2.3 Noise-induced errors : Operate the MCU in Wait or Normal Stop mode [...] immediately after initiating...

I recently measured 4.1uA in LLS, 3.6uA in VLLS3 and 3.1uA in VLLS1 -- out of three NiMH batteries.
What I do not know though is : are VLLSx a really better choice, given that in these modes almost...

Problem fixed!
Thanks a lot for your help.

Hi,

Thanks for the quick replies.

I just grabbed a fresh snapshot of Snooze from github, so it's 5.5.1.
I crafted a small test to show the case :
Given a TeensyLC, "24MHz optimized", powered...

Hello everyone,

I've been using Teensy LC + Snooze + VSSL1 for some time to implement a battery powered sensor that reports measures through an RF12.
The circuit reads a sensor, spits a packet...
