I'm unable to pass calibration procedure (D4D_CalibrateTouchScreen()). My touch screen controller is cr touch (d4dtch_cr_touch.c version, date Nov-24-2011). When I touch yellow cross, I get {25, 25} {124, 250} {225, 450} coordinates on the screen (that seems fine), but the code never passes


if ((X[0] > X[1]) && (X[1] > X[2]) && (Y[0] > Y[1]) && (Y[1] > Y[2])) // line 775 in d4d_low.c, version, date Feb-23-2011


How should I configure D4D or cr touch to pass the calibration procedure?
