I am trying to use REDUCED_CPU_BLOCK from Duff's Snooze library and it simply does not work.

While the differences in functionality between sleep(), deepSleep(), and hibernate() are left as an...

Dear duff, thank you for your Snooze library. T4 is currently useless to me compared to T3.5/6 because of the vastly inferior 24mhz power consumption vs the T3.5/6 at 24mhz. It isn't even the same:...

Thank you for the explanation.

Do you really think that the whopping 36ma-observed to 12ma-should-be disparity can be explained by activated additional peripherals on the device?

If this...

Thanks defragster for the help. I followed your instructions and I obtained the incredibly disappointing, inexplicable 36ma at 24mhz result. I hope there is a fix for that. I made a new thread here...

Paul, I love your products and would appreciate a technical explanation of the following disappointing phenomenon.

Long story short: Despite supposing to have WAY BETTER mhz/ma power consumption...

Clearly one of the most useful and amazing things about T4.0 is that, being that it is only using 100ma running full 600mhz, I should be able to run code 100% of the time at 24mhz using just 4ma...

Problem identified.

I had the optimization set to "Fast".

I realized this, and immediately had a wishful-thought that this was somehow corrupting the low-level operations within the Zilch...

Fascinating. Thank you for sharing. I am using TD 1.4.5 and Arduino 1.8.5 to reproduce the task.create() hang with this old LC-compatible version of Zilch.

I will reproduce once more then upgrade...

Thank you. While that version DOES compile (so, we're making progress!), it unfortunately hangs on any call to task.create() on Teensy LC.

E.g., the example "Simple_Task" and "Pause_Task" do not...

Sir, thank you so much for the response.

Can you provide a link to whatever old version which did work on LC, prior to rewrite?

As long as it enabled context-switching multithreading on LC, it...

Paul, thank you for your reply, and know that I am a HUGE supporter of your products.

Please see the "zilch.h" file which states at the very top:

See as though the Teensy 3.2 has TWICE the power consumption as the M0-based Teensy LC, I REALLY would like be to able to use my Teensy LCs that I have bought.

Has anyone got been able to get any...

Hello -

I am in love with my Teensy 3.6 + TeensyThreads implementation but have good cause to use my Teensy LCs for less intensive purposes though needing true multitasking.

TeensyThreads...

Don't worry, I am implementing exactly that with a ping-pong buffer that is in multiples of 512 and indeed much larger than 512. Writes happen much longer than every second except at full speed. That...

I have done more testing/research and append the following possibly-useful information:

According to Page 36 of the above-referenced PDF, at "8.1.1 Entering and exit conditions for each low power...

(Skip intro to next paragraph if you want) I am a veteran Windows programmer who is just getting into microcontroller programming. As my first post here, I want to congratulate Paul S. on your...
