A little off-topic, When testing the PS Vita 1000 Joystick at the first place I checked that wiring was correct but when going forward on my incoming built I noticed something "weird" about the joystick I received.
X and Y "potentiometer" are off-center, far far off (following value (X) come from ADC reading, not GPIO driver) :
min : 0x02C0 : 704
center: 0x077C : 1916
max: 0x09A2 : 2466
Sadly, there is no way to "correct" the problem via the GPIO driver itself, 'input_set_abs_params' function 'flat' argument (the last one) act only as a center dead zone.
Hipcat, did you encounter this problem in one of your build?
