The circuit of co nt roller for capacit ive touch panel is proposed. The circuit is composed o f 8751 single chip micro computer sy stem and co rresponding touch sensing circuit . The st ructure of capacit ive to uch panel is brief ly int roduced. T he hardw ar e circuit and funct ions o f the cont roller are also illust rated. T he principle and metho d for determining the coo rdinates of touched po sit io n are also g iv en. Using this cont ro ller, the informatio n about the posit ion and to uch pressur e can be obtained. T he info rmat ion is t ransmit ted to computer by serial or par al lel port . Based o n this information, userps applicat ion program can be designed. T he cont ro ller circuit and co rresponding co nt ro l sof tw are have been all r ealized.
