6.3.7 Touchscreen Device Drivers

+ +

+ NuttX supports a two-part touchscreen driver architecture. +

+
    +
  1. + An "upper half", generic driver that provides the common touchscreen interface to application level code, and +
    2. +
  2. + A "lower half", platform-specific driver that implements the low-level touchscreen controls to implement the touchscreen functionality. +
    3. +
