This driver has a number of optional settings which can be specified in gfxconf.h: #define GMOUSE_STMPE610_READ_PRESSURE GFXON Returns pressure values when the touch is down. On tested boards this ranges from 90 to 150. 255 is touch off. #define GMOUSE_STMPE610_SELF_CALIBRATE GFXON Scale the touch readings to avoid calibration. This is not as accurate as real calibration. #define GMOUSE_STMPE610_TEST_MODE GFXON Return raw readings for diagnostic use with the "touch_raw_readings" tool.
