Diablo PS4 Controller

Hi,

Ive been scratching my head for the last 5 hours trying to get the axisLeftRight to do anything with my PS4 controller using the diabloJoystick.py file

I have changed the axis reference to 3 as recommended in another post, but that dent do anything/ If I swap the axisUpDown from 1 to 3 and visa versa I still don't get any leftRight but I get UpDown on the right joystick by pushing left or right.... im quite baffled

this is what I have

also, can you remind me how to post code to the forum?

```

DIABLO.Init()
if not DIABLO.foundChip:
    boards = Diablo.ScanForDiablo()
    if len(boards) == 0:
        print 'No Diablo found, check you are attached :)'
    else:
        print 'No Diablo at address %02X, but we did find boards:' % (DIABLO.i2cAddress)
        for board in boards:
