The code: | /* Post events | * BTN_TOUCH has to be first as mousedev relies on it when doing | * absolute -> relative conversion | */ | if (hw.z > 30) input_report_key(dev, BTN_TOUCH, 1); | if (hw.z < 25) input_report_key(dev, BTN_TOUCH, 0); Nothing happens if z is lets say 27. How do I do fine tunning with evdev? This looks like nothing has any influence on 30 & 25. My minimum pressure seems to be around 500 and I didn't get it past 700. I get nothing if I touch lightly the touchscreen so I thing having nothing is allready sane. >Dmitry Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
