PixyMon works fine but when I use UNO to work, the getBlocks returns 0. Even the hello_world.ino cannot detect anything too. I use the SPI as interface. Can anyone give me some advice please. Thanks.
Hello Simple Pig,
Make sure you are using “Arduino ICSP SPI” instead of “SPI” for the interface. This can be configured in PixyMon:

This page describes how to hook up to an Arduino through the ICSP port:

Let me know what you find.
