Pixy Sleep mode

Pixy Software
#1

Hi,

I am using Pixy with a wireless sensor node(with Atmega1281 as micro-controller). I was wondering if there is a mechanism to put the Pixy into sleep mode using SPi interface to save the power consumption on the wireless sensor node. I want this functionality in order to prevent the pixy from contuining to draw power from the node even when the node doesn’t need the location data from Pixy.

Thanks!

Hi Priyanka,
There is no sleep mode, but I’ll add this as a feature request.

Hi,

Thanks for your prompt reply! It would be great if you add this feature as it is very much useful for wireless sensor node based applications.

I was wondering if there is a way to start and stop collecting data(tracking the object) from a Pixy to the micro-controller it is connected to, which might also solve my problem to a great extent.

Thanks in advance!

-Regards

Hello Priyanka,
I’m passing along!

Priyanka! You can cut power to pixy with a relay or a transistor when you dont need it running, I do it in my setup.

I would recommend using a relay or PNP transistor to cut + or VCC. Cutting - works too but not as well because interface pins (like i2c pins) still source some current!
