I am wondering how the Pixy SPI is implemented to determine what is the minimum frequency I need to get the bytes from it in order to read all the frames and objects?
Hello Alex,
I’m not sure I understand your question. Pixy acts as an SPI slave, so it doesn’t supply the clock (the master does). The minimum frequency to read the data depends on how many objects Pixy has detected.
But in general, each detected block is about 10 bytes of data, or about 100 bits. If Pixy detected 1 object, it would return 1 block every 20 ms. So the minimum frequency would be around 5KHz or kbits.
Hope this helps!
