Documentation says the Pixy can process 50 frames per second. So, it would make since that you wouldn’t want to get-blocks more than once per 20ms but I think that should be added to the documentation because it makes a big difference if someone misses that and tries to sample more often. In practice, I have found that 21ms works a little better.
Hello Ted,
Thank you for the suggestion! What kind of interface are you using (spi, UART, i2c?) Also, in your findings how is 21ms better?

I am using the SPI cable with an Arduino. I get about 99% of the time blocks returned with 20ms but 100% with 21%. For my application (obstacle detection for a robot) 100% is worth the 1ms so my bot doesn’t change modes.
