Hi,

This work was done on Crazyflie 1 and so the code is pretty old and will not work on Crazyflie 2.0, you will have to port the driver to Crazyflie 2.0.

The easiest way to add code to the Crazyflie 2.0 is to add it in the new deck api framework: https://wiki.bitcraze.io/doc:crazyflie: ... mware:deck

Thank you very much, I will try this method.
By the way Im not sure about the variable GPIO to connect sensor
+5 -> pin 20
GND -> pin 19
AN -> pin 14
It correct ? because I see the GPIO parameter in crazyflie2.0 firmware source code have only gpio_0 to gpio_15 how did I know which parameter I can use to connect sensor with crazyflie ?

Crazyflie is a 3V board, you should only connect 3-3.3V electronic to it.

You can find the pinout of the expansion port there: https://wiki.bitcraze.io/projects:crazy ... ort_pinout

you will have to connect 3V, GND, and one analog input. The deck API contains the analogRead function to read the value of analog inputs.
