I have set up a 5.7 inch display but the touch screen is very slow to respond. Is there somewhere in the registry where I can scan faster or select scan and sensitivity settings.
There are mainly three parameters that influence response time of the touch panel. But please note that faster response time in most cases reduce touch accurateness.
TouchSamples: Number of samples taken to detect one point. Default value is 7. Lower value will speed up measurement.
SamplePeriodLowHns: SamplePeriod in hundrend nano seconds (Hns). Default sample rate is 200000 (20ms).
SamplePeriodHighHns: SamplePeriod in hundrend nano seconds (Hns). Default sample rate is 100000 (10ms).
You can switch between high and low sample period by calling TouchPanelSetMode function.
