Thanks for yiur answers guys
I will try with Xinput, i had see it but not try it yet.
In the wait of your answer i cheat the sofware thanks to calculation.
As left hand + right hand = brake
I get a value of brake send to the y axis and keep the difference between left hand and right han values on x axis.
That solved my 1st problème
For the second on problem if we are capable to have mouse in our phone thanks to arduino why can't we replace signals from touchscreen ?
I am newbie but my think was if we can get the adress of the touch screen if we send value on these adress it should be understand by the phone and the game like if it was the touch screen working
Could you tell me why i am wrong please?
