@sirius

Please tell me how to fix pmw3901 initialization failure problem

You claimed that the problem was solved in your other post on the same topic
So is it solved or not?

Initialization of the optical flow sensor (pmw3901) failed

After connecting pmw3901 to Arduino Uno, running the bitcraze_pmw3901 flow example code will output as a "Initialization of the flow sensor failed" What's the solution to the problem? Connection sensor arduino mosi -> pin11 sck -> pin13 miso -> pin12 cs -> pin10
