Capacitive touch padTwo GPIO pins functioning as Touch Sense Input (TSI) signals, are connected to capacitive electrodesconfigured as a touch pad as shown in Figure 7.Figure 7. Touch pad connection4.5. I2C Accelerometer SensorMMA8451Q is a small, low-power, 3-axis, linear accelerometer. The device features a selectable I2C orpoint-to-point SPI serial interface with 8-bit accelerometer and 14-bit magnetometer ADC resolutionalong with smart-embedded functions. It is interfaced through an I2C bus and two GPIO signals asshown in Figure 8 and Table 5 below.By default, the I2C address is 0x1D.
