Data shift issue

Pixy Hardware
#1

Hello,

We have some issues for Pixy CMUcam5 as the attachment:

  1. The block will shift for a short time(about 30 seconds)
  2. The integral data become a combine in different block

We use I2C interface and get data in the frequency of 40 Hz currently, according to frequency, we have already tried some different setting from 2 Hz to 40 Hz, but get the same phenomenon.
Is this a normal situation?

Hello,
I’m not sure what you mean by “shifting”, but note that Pixy will return 0’s when there is no data available. For example, if Pixy has detected only 1 object, you will read the first object block and then the rest of the data will be 0s because there is no more data available. You will continue to read zeros until the next frame is processed AND it has detected at least 1 object. Note, a frame is processed every 20ms.

Hope this helps!
