You are right, the pressure values were being inverted on my hx4700. Pressing hard generates somewhat lower Rt values than pressing lightly. Since typical hx4700 Rt values are close to (pressure_max/2) anyway, the inverted and non-inverted values were not very different. For example: Rt ts->pressure_max-Rt 599 425 562 462 588 436 570 454 So by all means submit your ads7846.c patch; it will not break hx4700. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
