Title: NHD-7.0-800480EF-ATXL#-CTP Sensitivity in a high EMI environment
Post by: cborlase on February 16, 2016, 04:45:19 PM
We just received 5 of these displays, and are testing with our device with respect to EMI sensitivity.  When our device is pulsed with 2kV spikes on the input power, the touch panel coughs up spurious touches.

Hoping there's register settings that can help increase the controllers input filtering without reducing sensitivity.

We've been looking at ID_G_THPEAK and ID_G_THCAL, although the registers have no real description on behavior.

If you have any suggestions for where to adjust, I'm all ears.
