Version available in CVS (s3c6410_touch.cpp). * Measurement duration optimized to reduce risk of "hitting" up event. Delay before measurement will only be influenced by paramters AdcReadHoldoffHns and PenDownHoldoffHns. ADC delay will only be applied once. * Bugfix in PenDownHoldOffHns calculation (src clock is 12MHz not 3.68MHz) * Sample frequency increased to 3MHz * Verify if touch is pressed again after measurement. * Enable Up-Event detection during measurement by default (was implemented but still disabled) |
