Power consumption on Pytrack with SiPy

[Emmanuel Goudot]

I have now tested on Pytrack.
After sending "$PMTK161,028\r\n" to L76, it seems that I2C scan loose 16 ID (remains [8, 30]).
Is it normal behaviour ?

Then after asking for deep_sleep (py.setup_sleep(SLEEP_TIME) and py.go_to_sleep()), is L76 still powered (so it really stay in standby) ?

Third question: are electric schematics of pytrack avail to understand a bit more what is happening ?
And is SW of PIC16LF1459 also avail ?
Thanks, Emmanuel.

Hello, have a look at this post (tested power in deep sleep)

Is there an update on this topic? I was hoping to use the interrupts in a project next week.

@bucknall Can you give any updates on the availability of the interrupts?

[bucknall]

@joeri The library for the Deep Sleep Shield 'wake from interrupt' is available now. Daniel is working to implementing it in the Pytrack and Pysense and will be coming shortly.

Thanks,

Alex

@bucknall @daniel any update on this? When will be able to wake on interrupt with the Pysense, at least for external pins (EXT_IO4/5)?

Thanks!

Also eagerly (and a bit angry) waiting for this on pytrack but not to wake from deepsleep but just to have the interrupt routed to the esp32 as is shown on the pinout here:

This feature is advertised on the pinout but seems not available right now...

@bucknall @daniel I'm having quite some power consumption issues with a prototype due to the accelerometer interrupt not being available. Now I need to regularly wake the board on a timer to check for movement which is not efficient.
Is there any update on a timeline for this feature to be released?

@bucknall @daniel Can we get an update on progress here? I'm waiting on interrupt operation from the accelerometer as per the information I was sold the PySense board on!!

At least release the various schematics and information we would need to do this ourselves?

PyCom is quickly becoming great promises instead of great products. A lot of the reasons to pick your products over others are the fringe features you don't actually have but suggest you do.

Very poor and I'm sure I'm not the only one currently delaying projects and effectively loosing money after backing you as a supplier.

@bucknall @daniel my prototype is begging for sleep. any progress on accelerometer interrupt?

cross-referencing for relevant update (yay!)

@asaph I've tried it out and it works fantastically 🎉 Thanks @Daniel!
