18.1 Schematic
Please pull up resistor from touch panel I2C to TP power supply VCC_TP to avoid
increasing extra power consumption by power electric leakage from I2C bus to TP screen.
Fig 18-1
Pay attention to the withstand voltage of Charge Pump capacitor of TP IC, and the
capacitor should be placed close to IC pins, as shown in Fig 18-2.
