A touch control panel design scheme was proposed based on the capacitive touch screen. The HB6096 bus was used as the data transmission interface between the touch control panel and the on-board interactive equipment， and the FPGA was used as the main control chip.The control circuit received data from the capacitive touch screen through the I²C interface， packed and transmitted the data to the interactive interface through the driver， and finally realized the cursor movement and clicked selection functions on the display screen.
