-+// To customize for a new touchscreen, there are various macros that

-+// will get real time ts data scrolling up your serial terminal
-+// screen that will help you empirically determine good values for these.
-+//
-+
-+//
-+// These are used as trigger levels to know when we have pen up/down
-+//
-+// The rules:
-+// 1. TS_HEAVY_INV_PRESSURE < TS_LIGHT_INV_PRESSURE because these
-+// are Inverse pressure.
-+// 2. Any touch lighter than TS_LIGHT_INV_PRESSURE is a pen up.
-+// 3. Any touch heavier than TS_HEAVY_INV_PRESSURE is a pen down.
-+//
-+#define TS_HEAVY_INV_PRESSURE 0xFE0 //C00
-+#define TS_LIGHT_INV_PRESSURE 0xFFF //e00
-+
-+//
-+// If the x, y, or inverse pressure changes more than these values
-+// between two succeeding points, the point is not reported.
-+//
-+#define TS_MAX_VALID_XY_CHANGE 0x300
-+#define TS_MAX_VALID_PRESSURE_CHANGE 0x100
-+
-+//
-+// This is the minimum Z1 Value that is valid.
