After hours of fighting with Arduino Joystick, I'm install on my arduino a software called MMjoy2. It is simple to install and not too difficult to confugure. MMjoy2 gives You a lot of possibilities of calibrations. Off course it works perfect with Condro2
On YouTube You will find helpfull videos.
Remember that ports in MMjoy2 and on Arduino will have other names. For example A3 on Pro Micro is F4 in MMjoy2. I find a helpfull scheme on YT video.
