Dear Sir
We do the ‘group pulse experiment ', we add 5kHz, 1000V interfere on the power SYS5V(12V to 5V), with the resistance TP screen, then TP can not
work at this point.
the touch screen, did not receive any interruption, we wonder what is the problem of the Touchscreen Controller in CPU ?
BTW,this time the other part of the system is normal(work well), that is, the touch screen is not workable.
And if at the beginning,we do not install touch screen under the same group pulse experiment, then touch screen, is not workable,either.
Any body have same or similar experiment on this case?
Please help us to find the cause and solution?
