Hi, I use TSC2046 to control the touch screen.There is a problem. If I measure the AD value of X axis . I think that the AD value of the horizontal direction is linear variation,and the vertical is almost no change. But the fact is that the value of vertical changes a lot. I see the waves of X+,X-,Y+,Y- through the oscilloscope. I found the Y+and Y- waves is not horizontal,but oblique. Maybe this effected the AD value. I dont konwn why it is oblique. I send the command 0xD0，0X90 to measure the AD value. first ,help me to confirm the schemtic,tell me if it have problems. second , help me to analyse why the wave is oblique.thank you!
