Hello everybody! How to find out the firmware version of the optical flow. And how to flash the flow deck?

Hi skinnykaen!

There is no firmware for the optical flow deck, we control the PMW3901 module by writing a bunch of registers, as you can see in the driver code: https://github.com/bitcraze/crazyflie-f ... /pmw3901.c, we do not, however, have the ability to provide any descriptions of these registers.

Hope you manage to find what you are looking for!

Thank you jonasdn! You answered my question.

Great jonasdn! Also need it.
