Can be gotten using VPADRead(), length seems to control the max amount of "datasets" to keep. A single dataset containing raw controller data is 0xAC bytes.

Offset	Length	Description
2	2	Buttons, ABXY, Left, Right, Up, Down in that order (bits)
3	1	Buttons, ZL, ZR, L, R, +, -, Power/Home, Sync in that order (bits)
12	8	Left Joystick, vectors for X and Y
20	8	Right Joystick, vectors for X and Y
Touchscreen Input
82	2	Touchscreen X
84	2	Touchscreen Y
86	2	Flag for if touchscreen is currently being touched (1 = Yes, 0 = No)
88	2	Coordinate validation (0 = All Valid, 1 = Invalid X, 2 = Invalid Y, 3 = Both Invalid)
90	2	Modified Touchscreen X?
92	2	Modified Touchscreen Y?
94	2	Modified Flag for if touchscreen is currently being touched (1 = Yes, 0 = No)?
96	2	Modified Coordinate validation (0 = All Valid, 1 = Invalid X, 2 = Invalid Y, 3 = Both Invalid)?
98	2	Modified Touchscreen X?
100	2	Modified Touchscreen Y?
102	2	Modified Flag for if touchscreen is currently being touched (1 = Yes, 0 = No)?
104	2	Modified Coordinate validation (0 = All Valid, 1 = Invalid X, 2 = Invalid Y, 3 = Both Invalid)?
Other Data
160	1	Something related to volume slider
