Problem is ghost touch on my touch panel but when I connect the negative probe of the 12VDC power supply to the GND there is no ghost touch. I mean will be any problem if I keep the negative prob on GND ?What is the problem?
How is power connected to your board?
If that's the power supply for the board, the negative terminal must be connected to the board.Problem is ghost touch on my touch panel but when I connect the negative probe of the 12VDC power supply to the GND there is no ghost touch. I mean will be any problem if I keep the negative prob on GND ?
Of course I connect both positive and negative probes of power supply to the board also I connected the negative probe to the GND.If that's the power supply for the board, the negative terminal must be connected to the board.
Without knowing whether the power supply is isolated or how the ground on the board is connected with respect to earth ground, I can only guess at what the problem might be.
